Our take on the Infinity Primus P363

No matter where your movie and music interests take you, Infinity's Primus P363 makes an enjoyable traveling companion. The sound is detailed yet balanced, with dialogue presence that breathes life into every movie night, whether you're watching a gritty indie thriller or a lush period romance. Plus, the deep, clear bass adds a nice kick to your action flicks. And it also reproduces your music with robust, enveloping sound, no matter what you listen to or how loud you play it. It's all thanks the combination of Metal Matrix Diaphragm® driver technology and low-resonance enclosures that have made the Primus Series a longtime hit with audiophiles.

Rich sound from an affordable tower speaker

High quality drivers for top quality performance

The Primus P363 features Infinity's exclusive Metal Matrix Diaphragm ("MMD" for short) driver technology in the 3/4" tweeter, 4" midrange, and the dual 6-1/2" woofers. These MMD drivers consist of a stiff aluminum core, anodized on both sides for increased strength and rigidity. The result is extremely fast, extremely accurate response, giving you distinctly cleaner, more realistic sound, even at higher volume levels.

Build a complete Primus® system

The Infinity Primus P363 will fill just about any room with dramatic and well-defined sound. Use a pair to create a high-quality stereo system, or add it to Infinity's P163 bookshelf speaker speaker and PC351 center channel speaker to create a stunning Primus home theater system. And don't forget to add the perfectly matched PS38 powered subwoofer to get deep, accurate bass in the mix.

Thad from cleveland, OH on 2/11/2016

Crutchfield Customer Review (What's this?)

Bang for the buck it's there, arrived on time and was packaged like a tank.

Pros: These speakers are run by a Integra receiver with 95 watts, crank it up and they perform just fine. For the money go for it.

Cons: None

Great price...Average speaker

Rronzn from S.W. Florida on 2/8/2016

Crutchfield Customer Review (What's this?)

They arrived on time & in good condition. They work well but must have a sub for good bass response. Overall I'm satisfied & as a prior Infinity user will continue to purchase their products.

Pros: Good overall speaker, attractive appearance though the silver feet need to go (they did), solid cabinet with no noticeable vibrations even when placed next to a powerful subwoofer. As part of a 9.2 system they perform as expected, not quite as well as the Polk monitors they replaced but we'll enough that the Polk have been removed to another system in the home.

Cons: Those ugly feet!! No biamp option.

Fine sound, fine design

Alan P from Crestwood, KY on 1/19/2016

Crutchfield Customer Review (What's this?)

The Infinity P363 pair I purchased replaced a pair of my old favorite Cerwin Vegas. While they don't match the deep bass range of those 12" Vegas, they do an admirable job deep in the sound--especially in light of my changing taste in music and audio--and the very clear mid- and high-ranges make them a great fit for what I'm after nowadays. Set them in front of you with a powered subwoofer, and you're good. I can't wait to hear them in the new home theatre area I'm currently installing.

Pros: Design Crisp sound in mid- and high range Price point

Cons: Negligible, especially given price...if you want face-peeling, room-shaking bass-range, get something else.

Infinity Primus P363 Speakers

Michael from Texas on 1/10/2016

Crutchfield Customer Review (What's this?)

The speakers were well packaged and in GREAT condition. Because my system has 5 speakers, these two plus two Advent speakers and one small shelf speaker I had to adjust the speaker outputs on my A/V receiver to be sure everything was equal. The minute I inserted a BluRay disc into the player the room came alive with these speakers. I actually felt I was in a movie theater. I highly recommend these for the average Joe with an average system.

Pros: The quality of sound is fantastic. A great value.

Cons: None at this time.

Very impressed with these speakers, simple hook up and look very nice. Replacing a 16 year old set of Infinity's that were great in their day, but was blown away by these new ones with all the technology increases over the years. For the price point very worth it.

Pros: Nice bass, good mid and nice highs.

Cons: None

Crutchfield Customer Review (What's this?)

I liked these speakers they did as well as I expected. Solid in every way, mid range very nice. bass is solid although I would add a sub to help out. These speakers for the price is a steal. Running 5.1 All Infinity system. If you want a good solid system at a great price. Infinitys are your speaker and of course Crutchfield is where you buy them. Thank you to all the people that work for this great place, for all the help for all of theses years. MERRY CHRISTMAS.

Pros: Great sound for the price.

Cons: None

Very Nice

Upgraded my Sony ss5000 speakers. Wow! What a difference! A difference I could easily hear. As someone who has become more educated in audio as I've gone along, this was definitely an upgrade.

Pros: Sound great, full sound.


Not Bad at all!! for the price.

Speakers complete 2-year system upgrade

Albert S. from Sacramento, California on 11/23/2015

Crutchfield Customer Review (What's this?)

As of receiving my Primus P363 pair almost two weeks ago, my two-year upgrade project has come to satisfying end. I finally have the transparency and depth I've been seeking from my LPs, CDs, Hi-Rez discs and downloads! Right out of the box the difference these speakers bring is instantly heard. I hear new details in records I've listened to for decades, especially on LPs and older CDs! Jazz and classical titles particularly benefit but rock, R&B, electronic and other genres all sound great as well. I highly recommend these speakers to anyone wishing to upgrade to true hi-fidelity for relatively little money. Do not be fooled by the price. The Primus P363s are an insane value.

Pros: The 3-way Infinity speakers replace a decent 2-way model that just could not provide the clear highs and midrange I was seeking. This despite investing in power noise reducing equipment and high end speaker cables (Yes, cable quality matters as I've recently learned). Coupled with a good subwoofer, the Infinitys provide all the depth my small (20'x20') listening room could ever need. The speakers seem to disappear, leaving only wonderful music. I can't wait until these babies are broken in!

Cons: None, except I'm now spending way too much time listening to my music collection. Everything sounds so fresh again that 'listening fatigue' just does not happen anymore.

Crutchfield Customer Review (What's this?)

I installed these speakers in my Shop, which is 1000 square feet and with 11' ceilings. In using a powered sub-woofer, these speakers provide a great sound experience and I am delighted. Crutchfield provided excellent pricing as well.

Pros: Great mid-range and high notes and adequate bass.

Cons: None so far.

The Modern Age of Sound

Infinity primus 363 speaker from Washington on 9/28/2015

i purchased apair of these speakers, and within a week i knew I had to buy 2 more to complete my home-theater. they literally fill my entire room with evenly dispersed sound. no beaming or dull spots, just detailed, smooth and evenly integrated sound. my friends can't believe the price of these speakers. i don't know how infiniy -Harmon did it, but they did, and there's not better value in home audio

Pros: wide smooth dispersion, tight bass, smooth detailed mids and treble, easy to integrate into room, the speakers don't need a ton of power; perfect for home theater

Cons: really nothing, if i had to pick something i'd say no spike cones, but no big deal


LAROUX from Kansas on 8/23/2015

Crutchfield Customer Review (What's this?)

Awesome sounding speakers. Very clear and distinct. Bass tones are good but not deep. .

Pros: great sounding

Cons: Bass tones weak. will need powered subwoofer.

Awesome speakers

Tom S from Georgia on 8/19/2015

Crutchfield Customer Review (What's this?)

I bought these speakers for my home theater system. They arrived in perfect condition. Great job with packaging to protect them during shipment. These are by far the best sound for the price. Nice, crisp highs and resounding lows. I could not be happier! I highly recommend them.

Pros: Great value for the money.

Cons: None

Wonderful speaker!

AndyW from wadena mn on 8/16/2015

Crutchfield Customer Review (What's this?)

Wow! What great speakers for the price. The value is great for the combination of drivers you receive. Its hard to justify spending twice as much to get quality dual 6-1/2" woofers, 4" mid, and 3/4" tweet. Nice tower height puts tweet and mid at ear level when sitting, which is awesome in my 7.2 surround. Love how these speakers bring out the guitar picking when watching rock concerts on dvd

Pros: -Good bass -awesome mids -spectacular highs. -port hidden behind grille so my children cannot stuff toys in these ones

Cons: - spend less time outside because im listening to these speakers

Great sounding speakers




RENO58 from Florida on 7/20/2015

Crutchfield Customer Review (What's this?)

I was skeptical about buying the Infinitie P363s at first. It seem to be too good of a deal, But... when I got the same recommendation from two different advisers, I ordered a pair for the front speakers of my Infinity home theater surround system. WOW! I'm very happy with my purchase. I expected to pay a lot more for a quality set of floor standing speakers. Thanks to my product advisor, for the great advice.

Pros: Super highs, and mid-ranges, Great sound separation. Bass is ok, on it's own, But when you add in a sub-woofer, you have a complete package. They handle the power very well. Crisp and clean sound, and no distortion. I'm running a Yamaha rx=v677., 90 watts per, .5 channel w/ sub.

Cons: Only con is the bass is sub-standard on it's own, but you can easily overcome that with a quality sub-woofer. i have some advice for the people having problems with the terminals, If you run the recommended 16 gauge or heaver speaker wire, you will not have a problem and improve your sound quality.

woof from Florida on 7/15/2015

the black and red plugs/caps in the end of the terminals come out,, they ARE banana plug accepting , all you need is a small pocket knife or jewelers screw driver and pry them out !



First speaker purchase

Jacob from Crystal Lake, IL on 7/14/2015

Crutchfield Customer Review (What's this?)

I bought a pair of these speakers along with a PC351 center. The speakers themselves are as noted and perform quite well in my current setup. Given I dont have a sub yet they are able to output a decent amount of bass by themselves...however once I get a standalone sub it will be much better. My only complaint on them is the speaker terminals being capped, but its not a dealbreaker.

Pros: Price Great sound Surprised at the amount of bass it was able to give

Cons: Speaker wire terminals are capped and don't accept banana plugs

Always Wanted Infinity Speakers

Fox from Wisconsin on 6/24/2015

Crutchfield Customer Review (What's this?)

They're wonderful speakers. Not only in functionality, both in audio -AND- physical occupancy landscape and architecture, but visually beautiful and impacting as well. Almost to the degree of being called artistic.

Pros: Everything you could want and ask for in a speaker of this price range and quality.

Cons: Nothing of any significance.

Must have

Eddie k from New Hampshire on 4/28/2015

Crutchfield Customer Review (What's this?)

Let me start by saying that I love speakers and have quite the collection. I have PSB, Polk, DCM, and Cerwin Vega vs 150's to name a few. I must say that when I first heard these infinity speakers I thought something was missing. They seemed quieter than the others. I switched back and forth and found that it was actually noise, possible distortion, that I was missing. These are extremely accurate and clean sounding and have earned their position as my favorite sounding speakers. I do have them connected to a decent amp and have an infinity sub connected and couldn't be more satisfied. I use them for both tv and music on a daily basis without fatigue. I do read reviews of people complaining that they're made in China. My 2k dollar PSB'S are also made in China. I'm not happy about that, but unfortunately most speakers are made there now. They do, however, outperform my USA made DCM'S and Cerwins as well as my China made PSB'S and Polks. If you want a nice looking, clean sounding speaker, look no further!

Pros: Pinpoint accurate sound

Cons: None

Excellent, Well-Balanced Speakers

Brandon S from Illinois on 4/12/2015

Crutchfield Customer Review (What's this?)

I'm a professional musician and I love these speakers for their accuracy and detail across all frequencies. Coupled with my stereo Onkyo receiver, they remind me of studio monitors I've listened to in high end recording studios. The bass will be a bit unstructured for a task like professional mixing, but that's a drawback of all ported cabinets and not something I expect from this type of speaker anyway. That said, the bass is still very accurate. Bottom line is that they sound great! Clear highs, tight mids, and plenty of good bass. I certainly don't feel the need for a subwoofer in my 30' by 30' space.

Pros: Great sound. Great price. Look great with the grill off.

Cons: The cabinet wood and the feet could look a bit better, but it's certainly not a deal breaker.

Quite like them

Matt from the Washington, DC Area on 4/6/2015

Quite happy with my Infinity Set.



Excellent Neutrality

Carl from California on 3/22/2015

Crutchfield Customer Review (What's this?)

Nicely balanced, accurate speakers. They integrate particularly well with a subwoofer set to take over at 80hz and below. Terrific value.

Pros: Neutrality, balance, bass response, clarity

Cons: Plastic feet

Beautiful sound

Johnny K from Hilo, HI on 2/15/2015

Crutchfield Customer Review (What's this?)

The sound from these speakers is outstanding! Highs and mids are very clear and there is a sufficient amount of bass. Very satisfied!

Pros: Very clear, natural sound.

Cons: None.

Big Bang for the buck!

Adam from Oakley CA on 2/2/2015

Crutchfield Customer Review (What's this?)

Overall a great product for the money.

Pros: Deliveres clean sound. Even at very high levels. I listen to 80's Hair band music as well as modern rock. They can really put it out. Seens to be a good match for my Denon Avrx3000. Note: I use them my rear speakers.

Cons: They lack bass. Must use separate powered Sub-woofer. Velodyne sub sounds nice when paired up with all my towers.

Infinity Primus P363

Clarence C. from Louisiana on 2/1/2015

Crutchfield Customer Review (What's this?)

Excellent product especially at the asking price-nothing close under $1000

Pros: Very good low and excellent high frequencies, well constructed, wife pleasing. very low distortion.

Cons: Requires time to set up properly for best imaging, slight recessed midrange only noticeable on female vocals. Bass is very good, may want to add sub if you need more bass.

Have only been using one of these speaker for about 2 weeks. I am really enjoying the sound even though it is in comp. with a 35 year old one. I plan on getting it's mate the end of the month. Made my little UPS driver say ugh when he picked it up.



Big Boom

Dan from West Virginia on 1/5/2015

Crutchfield Customer Review (What's this?)

I got theses speakers solely by telling the salesman what I wanted in sound, performance, etc. He didn't even take a second and put these on my list. I am old school when it comes to audio equipment, and still not very good at the tech parts. When these came I sort of laughed. He said they would rock, and do it loud, and when I saw the size of the speakers I was scared. Well to make it short and sweet, they rock, and rock loud with nice quality sound. I am not disappointed at all. I wish I had a nice bank roll I would put them all over the house. And a little hint if your not familiar, I noticed after using and breaking in they got a lot better. You do have to adjust them to your liking, but what speakers do you not?

Pros: Nice sound, crisp, amazing base for how tiny. I haven't tried to push them to their limits, but you won't need to if your pushing them with the right stuff. I've had a neighbor 125 yards away come over and tell me he could hear it over his football game:)

Cons: Not really a con, wish the covers were easier to keep clean, their dust magnets. But no biggie.

Great Tower Speakers

Columbus John from Columbus, OH on 12/30/2014

Crutchfield Customer Review (What's this?)

I had missed the great audio days of the 70's. Recently I purchased a Yamaha RX-V477. I wanted to get speakers that would compliment that unit. The Infinity Primus P363 tower speakers, P153 bookshelf speakers, PC251 center speaker, and PS38 woofer are great. My music sounds great. Watched a movie with the family and felt like I was in the theater. Great speakers.

Pros: Sound reproduction is very good. Enclosures allow the sound to be natural.

Very accurate speakers that can be played at life size volume. They are especially good for classical music and jazz. Really sparkling highs. Base is accurate and resonate, but not out of balance.

Pros: See above


Excellent speaker

RWhite from Williamsburg, VA on 12/1/2014

Crutchfield Customer Review (What's this?)

These speakers (along with the same series center and subwoofer) were purchased to replace some Onkyo Home-theatre-in-a-box units. The Onkyo receiver was toasted by lightning and replaced by a new Marantz SR-7009 "Atmos" system. It became apparent that the new receiver "needed" new speakers. These were purchased at the recommendation of the Crutchfield advisor. The price was awesome, and we had some Infinity speakers years ago that we liked. Great sound, shipped fast (overnight and free to Virginia), and minimal setup.

Pros: Great sound, quality build, fast setup.

Cons: Be aware of the size -- not small or lightweight. My wife thinks the silver feet are tacky, but Infinity provides some black, unobtrusive feet as options.


Kerry C from Lafayette, IN on 11/23/2014

Crutchfield Customer Review (What's this?)

They work.

Pros: Look awesome.

Cons: When you screw down the wire post caps they cut the wire off. I guess I don't know what I am doing but we managed by just wrapping a loop around the post and screwing them down that way.

Still going strong

Michael G from Colorado on 11/8/2014

Have these with the matched center Chanel in a small living room. they have been heavily used over the past three years and still sound great. For the price they are well worth it. They sound fantastic even when up very loud. my room is almost square and far from ideal for sound so I have noticed the sound is even better/fuller from my 2nd story hallway. I don't believe these sound as full as the klipsh set up my dad has however he paid twice as much. I am very happy with these for the price. I'm building a theater room in my basement and can't wait to see what they sound like down there.

Pros: Price, volume, all around use

Cons: Not very pretty I don't like the silver bottoms. You need a sub to really get nice depth

Infinity Speakers, sounds good.

Mrog from Seattle, WA on 7/7/2014

Crutchfield Customer Review (What's this?)

Primus P363 . They sound clean and crisp, lacking on the bass, but I am running with a subwoofer so it makes up for it. Maybe a little on the higher end of the audio spectrum, could sound a little less highs.

Pros: Good looking, sound crisp.

Cons: lacks bass.

Great Sound

Kevin G from NYC on 7/6/2014

Crutchfield Customer Review (What's this?)

I bought a pair of these to replace my 30 year old floor speakers which are primarily used for music but I run my TV through the receiver too. My old ones seemed to have lost their bass so when I hooked up the Infinitys I paid special attention to the bass. The overall sound quality was a radical improvement from my old speakers but I wanted to experience what a subwoofer could add to mix. I hooked up a powered subwoofer and the bass did indeed sound nice. Now I wasn' t looking to turn my living room into a disco so I kept the subwoofer set fairly low. I didn't like the booming floor-vibrating thump-thump that could be produced. Bottom line, I found that the bass level that sounded really good to me was coming from the Infinitys, not the subwoofer. I guess I didn't let them break in fully before I ordered the subwoofer. Net outcome: Subwoofer returned and speakers sound great. Just give them a chance to break in.

Pros: Great sound (bass included), great price.

Cons: Not a problem in my case, but make sure you have room for them - they're fairly large.

Great sounding speakers

Matt from Slatington on 6/9/2014

Crutchfield Customer Review (What's this?)

These speakers have very good high's, mid's and low's to them and that depends on how you set your system up or what your system can do. You do need a sub to help bring the deep lows out. The woofers on here are not designed to work like a 12 or 15" woofer, yes they have good bass but a sub will help even more. I would recommend these to anyone and love the way they sound.

Pros: Good speaker at a good price

Cons: None

Beautiful in every way

Colin F from Edison, NJ on 5/11/2014

Crutchfield Customer Review (What's this?)

I have these speakers hooked up to a 120V Harman Kardon amp, and they get LOUD. They sound awesome at all volumes though, and put out a surprising amount of bass. I ended up buying a powered subwoofer to go with this system but in all honesty it barely needs it, just adds a little punchiness on bass hits. Clarity is great, I listen to a lot of electronic music I think they really reproduce well. Also they are some of the prettiest speakers I've seen. No regrets with my purchase!



Great Sound

Mark B from Elizabethtown, KY on 5/10/2014

Crutchfield Customer Review (What's this?)

When I bought these speakers, I was looking for a change to my system. They look good, they sound good, and match up well with my living room which is a decent size. For the money I paid, they are way more than worth it. These speakers are worth twice as much as they are listed for.

Pros: The High's and Midrange are really good, and I can hear things in movies, or watching sporting events that I never heard before.

Cons: I do not have any cons, but they are larger speakers, so you will need the room.


J. from Chicago on 4/21/2014

Crutchfield Customer Review (What's this?)

There is not a single speaker on the market that will deliver what you will get with the Infinity Primus P363 speaker. Especially for the price. I'm an audio person to begin with. My previous speakers were Infinity RS-b's that my dad purchased for me when I was in junior high school. Those speakers were just retired 2 1/2 years ago....after 30 years of fantastic service! I listen to almost every genre of music and my old Infinities flat out kicked butt! In fact....I am hanging on to them and might have them rebuilt. Infinity is a fantastic product. The Primus-P363 speakers are absolutely the best bang for your buck on the market! I've listened to hundreds of speakers.....none of which could ever rival my RS-b's.....well that is until I hooked these bad boys up! Trust me....unless you're one of those idiots who loves nothing but thumping bass......which it seems applies to most people....these babies provide plenty of depth! Listen...they flat out thump! But more importantly....along with their fantastic bass output....they provide the complete, total full range of your mid's and high ends perfectly! You get the full spectrum with these suckers. If you have a huge living space....and you want home theater, well might want to add some accessory speaker systems. But there are many things to consider before purchasing your speakers and the size of the space they will be used in is one of them (along with other components). Buy now!

Pros: Bass range has plenty of depth especially when placed close to wall or corner, great mid-range production and a quality tweeter make this speaker the best of it's kind for the price. $1000+ dollars of high quality speaker sound for a bargain price! Sound is most important...and they sound as good as they look.

Cons: Absolutely none!

Just got the speakers a week ago so they're not even done getting broken in and they already sound amazing. Very crisp with mid and high tones, bass is not strong by any means so make sure to have a sub.

Pros: Awesome mid and high range.

Cons: Bad bass levels

Awesome speakers. I was thinkin to buy this ones like for 65 days. They are not really cheap but they worth the money. Sound is beautiful and clear. I can listen my salsa better now. I use to have a bose system. Bose system is crap compared to this speaker. More quality sound. Now i notice some instrument that with my bose system i could not notice.

Pros: Sound is clear and pure.

Cons: The only con. Is that i can complaint about this speakers.

RonM from Oakton, VA on 1/26/2014

Crutchfield Customer Review (What's this?)

Very happy to have these speakers at a great sale price. I was looking to replace my very old speakers and wanted something that sounded good mostly for music in a medium size 12 x 20 room, with good range but not over powering on the base. Although I haven't had them long and am still checking them out, they seem to be exactly what I was looking for. Need to spend a lot more money to get only a little better sound quality

Pros: Good range, clear mid tones and highs, and ample base.

Jim from Oklahoma on 1/23/2014

Crutchfield Customer Review (What's this?)

This isn't the first time I have had Infinity speakers. I had them way back when Circuit City was selling them, about 10-12 years ago, back then they were the SS and CS series. I had the CS3007's, they were pretty awesome. I then switched to Boston Acoustics for several years and just recently wore the BA975 (powered towers) out, both of the powered subs went out. My wife decided she didn't want another powered sub sitting around the house and it was going to take me forever to save for the Paradigm Studio 20's I wanted. I was looking on and came across the Infinity's. I remembered how good they were back in the day. I also noticed that they were on sale and since they were floor standing speakers, maybe I wouldn't miss not having a powered sub. When they arrived I, I hooked them up right away. They sounded really good on just about anything I played on them. They do take sometime to "warm up" though. But when they do they are great speakers. I do miss the powered sub, but for most people the bass will probably be adequate. However, the bass is better on movies versus music, don't really know why. My wife said after 30 years of rock concerts and loud stereos I am lucky to be able to hear them at all. I am currently saving up for the 3 way Infinity center, am currently using my Boston VR920. Anyway, they are as good as I remember and I am really enjoying them, the wife and kids love them, so we are good!!!

Pros: Great sounding speakers and nice looking.

Cons: None that I am aware of.

Outstanding and just what I was looking for!!

Infinity Primus 363 speakers: I've had them installed for 2 weeks. As many have said, there is a definite break-in period. The speakers are exactly what I was wishing for. The sound is big, crisp and pure. What I got: My sound is now pretty incredible. I'm now experiencing sound that I've always wished for but didn't think I could afford. I especially wanted the mid-range and it's doing its job very well. The 363's are bringing out mid-range and highs like they were supposed to be heard when recorded. I'm listening to all my music on my Stereo setting and my movies on the Dolby D. I'm experiencing a new world of movies and music. Like other reviewers, I'm playing music I've played for years just to experience the sounds I've not heard or are now enhanced by my 363's. I have found it's important to play with the equalizer on my iPod once I had my speakers calibrated. I am absolutely sure that anyone giving a bad review on these speakers has to have had other issues going on like bad speaker calibration or equipment issues. I am beyond satisfied with my Primus Infinity 363,s and I'm finding I'm hanging out in front of them every chance I get. The speakers are stylish and fit in very well with my living room/décor. They actually polish off my decor. My listening taste spans numerous genres. I'm in music heaven as well as movie heaven. Thanks: I'm not much of a review writer but felt compelled to write this one. The reviews I read prior to my purchase (greatly) helped me chose

Pros: Crutchfield: User friendly website. I ordered these speakers Sunday afternoon and they were sitting in my living room Wednesday afternoon. Crutchfield exceeded my expectations. I'm a first time customer. Incredible sound. Stylish.

Cons: None

Mind Blowing!

Jay from Massachusetts on 1/16/2014

I just received these speakers in today and after getting setup and getting my first listen, I must say I was absolutely blown away at the music detail. From crystal clear highs, to nice tight bass they are truly the best speakers I've ever owned (and I've owned a lot) The 4" midranges on these are truly amazing. They really bring out the vocals in the music. I had high expectations when I ordered these and I certainly got it, and then some!! I've always been a big fan of Infinty and they certainly are going to keep me as a customer. I've never been disappointed.

Pros: Clear highs Smooth midrange Tight, accurate bass Overall great value

Cons: Call me biased but I can't think of any

Very pleased

MasonN from St. Louis, MO on 1/14/2014

Crutchfield Customer Review (What's this?)

I have a pair of these towers hooked to a 5 channel Denon receiver and could not be happier with the sound. They are replacing two home made cabinet loaded with a pair 6x9 infinity car speakers, and the difference is astounding. A majority of the sound difference I'm sure can be attributed to my lack of craftsmanship in on the home made enclosure, but that just reinstates my belief that the people at infinity really know what they are doing. The tweeters are very bright and natural sounding, and the woofers are able to create adequate enough bass as stand alone. I do plan on adding a powered sub, as well as fill the remaining 3 channels on the Denon with infinity components, but I am overall very happy with the way these towers sound.

Pros: The tweeters are immaculate, the mids are great, and the bass sounds very good. The whole range of the audio spectrum can be represented with these towers. They look great, and the fit and finish seems as though it SHOULD last a while.

Cons: The lower end of the sound spectrum is slightly lacking, but that can be expected from a cabinet that relies a pair of mid sized drivers. The size of these towers should be taken into consideration upon purchase because they are rather large.

These speakers are fantastic! I own the Primus p150 & the Primus p162 bookshelf speakers. They are good but can't hold a candle to the p363's. I power the p363's with a NAD 315BEE and the sound is rich and full. The bass is so good I don't even have my Polk subwoofer hooked up anymore. All in all a great value.

Pros: Big sound for the money

Cons: none

RonO from Bayonne,NJ on 5/25/2013

Crutchfield Customer Review (What's this?)

I would love to give 5 stars but, I really was wanting just a little more bass. It has a perfect mid range and high frequency ranges. The bass is simulated in a way but not to be too hard on the eardrums. Of course they are not loud speakers like in the past but they bring a nice balance to movies.

Pros: Thin design, great sound, blends the frequency ranges nicely


Good things come in small bundles

Emmanuel from Lubbock, TX on 4/16/2013

Crutchfield Customer Review (What's this?)

This speaker is not the most towering floor speaker out there but it's certainly bigger than I thought it was going to be. But even more impressive is the sound that came out of this thing. My god!!! Forget all the technical mumbo jumbo about highs, lows, midrange, impedance , and what not. I know what I'm hearing. The price certainly had me fooled. This thing sounds like $500 apiece speakers. Some of the reviews I read b/4 buying mentioned a break in period on bass reproduction. I didn't have to wait--this speaker hit the ground running. For the record I'm pairing the speakers with Marantz PM5004 Integrated Amp. and a Rega RP3 table with Elys 2 cartridge. Yeeees, suhhh!!! its' a' good to be back in the land of vinyl again. Honestly, I can't say that either vinyl or CD sounds better than the other. All I can tell you, my friends is that vinyl sounds different from CD and if I had pick one of 'em on any day of the week I say give wax. If you are on a budget and looking for a speaker that sounds like money is no object then this is your speaker. Plus, Crutchfield will get it to your doorstep in without much hassle. Great job, fellas! If y'all excuse me I got some records to listen to.

Mark A from Normal, IL on 4/4/2013

Crutchfield Customer Review (What's this?)

These sound grrrreat for digital sources and playing dance/rock music loud but if you are hooking it up to a turntable, this is not for you. I had these discontinued Pioneer bookshelf speakers that put these floorstanders to shame hooked up to a turntable. I appreciated the sound of vinyl so much more than digital, but not with these floorstanders. Also, there was a crackling in one of the tweeters out of the box so I sent it back.. Overall, the bass is not tight enough and I always kept it as low as possible. The midrange didn't wow me. Take my advice and put the same amount of money into bookshelfs. Your paying extra for the sexiness and loudness.

Pros: looks sexy, very Loud, Great for digital sources

Cons: bad for turntable sources, bass is not tight enough, extremely heavy.

Pleasant Surprise

AlMc from Sykesville, MD on 3/24/2013

I purchased these on advice from the Crutchfield rep with whom I spoke over the phone. Now any old high fidelity enthusiast knows you can't buy speakers over the phone or Internet since you have no idea how they will sound in your home. But the Rep was very concise in describing the relative strengths and weaknesses of various speakers that I asked about. My biggest concern was the limited power that I would have - 65W per channel using a Denon RCD n7 multimedia receiver. But i also wanted a decent powered subwoofer to accompany these since the Denon had subw output. So he thought these would work for my application - a lot of vocal jazz, soft rock, blues, oldies, and even flamenco guitar and some classical. So I took the plunge and bought them based on his recommendation. I also bought the Infinity PS410 sub on his recommendation. They arrived two days later this past Monday. Boxes were not damaged, and neither were the speakers. The Denon arrived this past Friday. Hookup was simple with the monster cables I also bought. What a pleasant surprise! These speakers instantly impressed me and my family, all music lovers. Everyone is blown away how clean these sound with great definition in the midrange. Bass is very adequate for us and they haven't really been broken in. Highs are smooth and not peaky. While the subwoofer provides the floor shaking thump, the 363's hold their own very nicely. Volume is impressive given the limited power of 65W, despite the low impedance.

Pros: Great looking, slender tower, smooth sound across the entire range, Excellent definition especially with vocal reproduction. Quite efficient despite low impedance. Excellent bass unless you need to rattle the roof shingles (I don't). Great value for the price.

Cons: Can't think of any. Haven't heard any.

Surprised with bass response after break-in period

Gino R from 10457 on 3/11/2013

As the title states, i was in for a surprise of just how much bass these speakers produced AFTER its break in period. About 10 days for me or about 8-12 rather loud music time. When I first tried out these P363, I immediately noticed two things. Really nice highs & clarity but not the bass response I was looking for. I immediately began to cherish my 10inch Klipsch sub woofer even more. I was content with having the sub on at all times to compliment my new setup. No big deal to me because my vocals and mids were already a great gain for me for such inexpensive speakers. Infinity speakers nonetheless. However about a week and half later I began to notice how much more bass response I was getting from these bad boys. Having a wall behind the speakers also help. I have since shut off my sub and only have the sub on about 10-15% of the time when playing music. And trust me I lovvvve bass, I never imagined the day my sub would be dang near permanently in the off position but thanks to whatever the break-in cycle did.. It did it well. I'm really happy with these speakers. The craftsmanship and quality of the materials used in the P363 would make your head spin as to how inexpensive these speakers really are. If you just purchased these speakers and are disappointed with the initial bass response you're getting just like I was, PLEASE..Give yourself a good 10-15hours of heavy music time to break these subs in. Something truly magical happens in this break-in period.

Pros: Great sound. Real good bass only after the break in period. I'm using a Yamaha RX473 receiver to power my Primus. Great value at this price. Great craftsmanship, sleek & sharp looking unit.

Cons: Initial break in period is a must. It would deceive anyone into thinking these speaker lack bass during its initial setup. The speakers should come with some sort of advisory sticker right on em about how important it is to break these speakers in for proper bass response.


GW from Danville, IL on 3/3/2013

I bought these to replace a set of Cerwin Vega VS-150's. For those of you not familiar with the VS-150's, they are easily the best speaker Cerwin Vega ever made, but they are HUGE, and I was looking to free up a little space. Besides freeing up space, I was also hoping to get crisper highs and clearer midrange from the P363's compared to the VS-150's, but that simply wasn't the case - all I did was sacrifice ALOT of bass! Sure, the P363's have a nice punchy "mid-bass" to them, but anything too low simply overpowers them. It seems like I am constantly adjusting the bass level on the receiver with each new song that comes on! That wasn't so with the VS-150's - set the bass levels to maximum and never touch it again - nothing bothered them. I do run a powered subwoofer in my system, but it seems like there is a BIG gap in the bass range between where the sub cuts off and the P363's can comfortably take over. I will give the P363's more time to "loosen up", but I have a feeling the VS-150's will be returning to duty soon.

Pros: Slender, space saving design and attractive.

Cons: Can't handle low range bass - period.

Pros: They're great.

Cons: Really??? None.

Great Speakers for the Price

rick4946 from Dallas, Texas on 1/24/2013

These are great sounding speakers matched to a Vintage receiver. Good clean deep base with no need for a sub, 80 watts would be about the least power per channel though leaving a lot of AVR or surround sounds out of the picture.

Pros: Good clean sound with at least 80 watts per channel or more

Cons: Cheap looking black cabinet makes them look like the cheap modern day electronics

The receiver makes a huge difference!!

Tim in Illinois from Channahon, IL on 1/18/2013

Having been a drummer for more than 35 years, I can appreciate great sound, especially percussion. These speakers are excellent at reproducing music very accurately, with realistic and clean bass. If you enjoy hearing music the way it was recorded, you will love these speakers. Be warned if you plan on a sound check of these before buying; the receiver is the key. Garbage in, garbage out. Ask the store to hook up a solid 2 channel receiver to these and you will end up buying them. I almost passed them up during my sound check, as a Denon theatre receiver was hooked up to them, with no bass or treble control. Very bland until I asked for a medium range 2 channel yamaha hooked to them. Was loading them in a shopping cart after one song.

Pros: Very responsive and clean, best in price range IMO

I'm 57 years old and grew up with such speakers as JBL Century 100, AR 3a and Bose 901. I'm still a bit partial to the Bose series but I can say with no doubt that these Infinity speakers are at least as sweet sounding as the old AR 3a which I loved. You can't go wrong here.

Pros: Clean sound, tight base.....the snare drum reproduction is just incredible.

Cons: None

crownjules from Marlborough, MA on 12/17/2012

Crutchfield Customer Review (What's this?)

Let me first state, I am no where close to being an audiophile. My experience with speaker equipment is very limited. I purchased these P363s to start my first home theater system. These are connected to a Denon AVR1612 and matched with a F12 subwoofer. Using them for the last few weeks, I'm very pleased with them especially considering I got them on sale. The highs and mid sounds they produce are what I believe audiocentric people would call "crisp" or "clear" - sound is very well defined and not muddled at all. The construction is very well done and the speakers look great. The connections in the back are of great quality - they are metal, unlike the Denon which uses cheaper plastic fasteners to keep speaker wire held down. Overall, these speakers are a great buy.

Pros: Crisp, well-defined sounds in the range it covers. Constructed using quality materials. Great looking speakers.


Infinity Primus P363 Speakers

LarryC from Albuquerque, NM on 12/6/2012

Crutchfield Customer Review (What's this?)

We had a Sansui 7000 260 watt amp and 2 Sansui SP-3500 speakers, for music, movies, etc. The speakers sounded great, but we had no center channel for dialogue in movies and TV shows. Local stores often didn't have knowledgeable salespeople, and how do you rate a speaker sitting out on the floor of a huge warehouse type room with 20-foot ceilings anyway? The Infinity Primus speakers got good reviews, so we took a chance on an internet order. Crutchfield got our order here on time, with only one damaged box. (Speaker was OK.) Our intention was to keep our Sansui speakers for the rear pair, and put the Infinity speakers up front, along with their PC351 center speaker. When we hooked them all up, we were very disappointed in how the new Infinity speakers compared to our 40 year old Sansuis. I finally gave up, and moved the Sansuis to another room, to use as a separate zone, where they do just fine. Those things are brutes, with two 2-inch tweeters, 3 different midrangers, and a 14-inch woofer. If I had it to do all over again, I'd look for 2 more Sansui SP-3500's, and a good center channel. The Infinity speakers do seem to be loosening up some over time, so I gave them 3 stars, but they aren't as good as the artifacts I already had. We've since found out the SP-3500's are considered collectors items, sought after by some stereo buffs. The upper end Infinity speakers may be really good, but these didn't meet our expectations. Get what you pay for?



Good speaker for the price.

dcmorris from Lexington, SC on 11/13/2012

Crutchfield Customer Review (What's this?)

I got a pair of these to replace my 30-year-old Fried Model As, because one of them started failing. That was sad, since those speakers were excellent through all those years. They cost $500 for the pair back in 1982, and if they were still being made today, would cost twice that much, or more. The Infinity Primus has a good frequency balance and goes down quite low in the bass. The very low bass booms out a little too much for me, so I end up turning down the bass knob on my amplifier. And the bass isn't quite as tight as the Fried nor as well integrated with the other frequencies, but again, I am comparing apples to oranges. The imaging is quite good, but not as precise as the Fried. However, for the price, they are quite good. I haven't personally listened to other brands recently, so I can't compare them to Klipsch or Polk speakers, for example. The best speakers I have ever heard cost thousands, but I am quite satisfied with my Primus. If you want a less boomy bass, you could get the lower model that doesn't go down as far.

Pros: Good quality for the price. Good overall balance and imaging.

Cons: Imaging not as precise as expensive speakers, but good for the price. Low bass is a little boomy, but can be controlled by the bass button on the amp.

Nice Speakers!

Mark from Roscommon, Mich on 11/10/2012

I bought these because one of the best car sound systems I remember hearing consisited of Infinity Kappa 6 x9's. These speakers will not disapoint, all the detail in the mid's are there and I run 2 subs but don't really need them, half the time I have them turned off unless I want to feel the bass. I've owned a few brands of the narrow space saving towers and these have the best bass response. Speaker cabs are good looking but not great, you can tell Infinity put the money where it counts, in the speakers.

Pros: Good mid's lots of detail, good full sounding bass

Cons: Tweeters alittle harsh until broken in.

i bought these to replace aging Infinity SM112 speakers. i was a bit worried that the new Infinity's wouldn't "thump" as much, being that my old speakers had 10" subs incorporated in the cabinets. i am pleased to report the new P363's thump even harder. they look great with or without speaker grills. at first, the speakers sound a bit veiled from what i am used to (i prefer warm, full sound and do not typically enjoy 'bright' speakers), but i have already noticed after breaking them in they sound better and better. they are powerful too!

Crutchfield Customer Review (What's this?)

I bought these speakers for stand alone music only. As an old audiofile once told me, music comes from in front of you, not from around you. (If you have good seats) I replaced a very aging set of JPW's and from the first listen I was blown away. Highs are crisp, mids are realistic and the lows (contrary to some reviews) can vibrate the floor. They are extremely efficient. I'm running them through a tube amp I built from a kit that only produces 16 watts a channel and they produce a clean powerful sound. One came from the "scratch and dent" dept. Try as I might, I couldn't find a single issue. Cudos to Crutchfield.

Pros: Good looking, great sounding speaker. Great service all the way from the rep at Crutchfield to the condition of the speakers when they arrived.

Cons: None, unless you want to consider I should have done this long ago.

infinity primus p363 tower speaker

bluesman 12 from Hartford WI on 10/23/2012

Crutchfield Customer Review (What's this?)

The Primus p363 is quite honestly a serious performer. Given my age and & enthusiasam for music I have been through many famous brands and types of loudspeakers. I have played music live in various bands & in various venues,so I pretty much know how that sounds. With a good amp or reciever these Primus will really open up accurately &with awesome authority. Very neutral with good mid range presence making them ideal for home theater. These are NOT low end spkrs. Infinity has always built some of the finest loudspeakers in the world. Primus uses the same technology. I guess you can say I love EM!.

Pros: Highly efficient-93db. Plays louder with less power. But don't be afraid to power them up. IF you are not at all worried about going deaf, pump150 or so watts from a stable amp like 2 crown mono blocks. Nice styling. Front ported into the listening room. Mid range located at ear level a decided improvment for voicing clarity. Superb crossover network, at 24db/octave.

Cons: none so far!

Joshua J from Minneapolis, MN on 9/28/2012

Crutchfield Customer Review (What's this?)

Growing up listening to movies and music through my JBL Soundgear 3030, I have always held Harmon International products in high regard. When it came time for me to finally assemble my own home theater system, I was expecting no less from these Infinity speakers. I've created a system of 4 P363's towers, 2 P163's bookshelfs, a C351 center, and a PS312 sub, all powered by a Harmon/Kardon AVR3650. Being a bargain hunter, I waited for these to go on "sale" to obtain the best price (well this side Black Friday sales prices). I have had the speakers hooked up for about two months now, and all I can say is WOW! The sound reproduction and tonal quality is incredible. Everyone has their own opinions on what sounds good, but ultimately the quality of the sound comes down to the quality of the receiver and the quality of the speaker components. I've utilized various mediums ranging from music, movies and video games, and in each medium, even with works I know quite well, comes alive- whether connected via HDMI, fiber optic or composite. There are qualities to the sound that I did not know existed- that is how incredibly clear the sound is. I would definitely recommend these speakers to someone looking to obtain the best sound for the price, while still having a high quality product.



Infinity Primus P363 Floor-standing speaker

SteveL from Buffalo, NY on 9/2/2012

Crutchfield Customer Review (What's this?)

The Crutchfield sales associate recommended this particular model over the Infinity speaker that I had initially selected. He thought that I would be more satisfied and not mind the additional cost of $50 per. He was right on! This speaker is phenomenal and fit my needs exactly. Superb overall sound quality with outstanding base response particularly considering that my system does not include a sub-woofer. Delivery was prompt, free and arrived in perfect condition. Many thanks to the Crutchfield team!

Crutchfield Customer Review (What's this?)

I purchased a set of these along with a set of P163's and a PC351 along with an Klipsch sub 12. The sound from these are excellent! The multiple speakers keep up with anything I put them through with the Onkyo receiver I have. And believe me, I put them through their paces! Superb quality speakers that I recommend to anyone.



Infinity Primus P363

craig from yuma az on 8/31/2012

These are very sharp looking and the sound is cyrstal clear with high clarity. They do not put out the deep bass that i hoped for, so now i plan to by the Infinity subwoofer to go with them. You get what you pay for.



Awesome towers for the price!

JakeInPortland from Beaverton, OR on 8/11/2012

I just picked these up last weekend and they sound great. Especially for the price! I noticed that Frys had them on a one day only sale for $99.99 each!!! I quickly read a handful of reviews and stormed out the door. These were purchased to replace my older Klipsch SF-1, and what an upgrade they were! AND since they were so cheap the upgrade was totally free as I was able to get $200 for my Klipsch on Craigslist. Don't hesitate on buying these if you can get them for the right price!

Pros: Crisp, clear highs. Nice full mids, and plenty of low end for my 5.0 setup.

Cons: Price is inconsistent among retailers.

Great sound

Crutchfield Customer Review (What's this?)

Great sound, i am very happy with them!

Pros: Awesome sound

Cons: Raised feet are not as stable on carpet as I would have liked, since the speakers are front heavy the tend to lean forward. I cut 1/4 inch off both of the back feet and now its perfect

Excellent speakers for the price

Jake C. from Jacksonville, AL on 7/16/2012

Crutchfield Customer Review (What's this?)

Speakers give good, crisp highs from the tweeters. Also give nice range through the mids. Bass leaves a little to be desired, but is perfectly fine when accompanied with a subwoofer. Definitely worth the money. Speakers perform well for home theater use as well as in stereo arrangement for music.

Pros: Clear from highs through mids.

Cons: Bass lacks punch.

TP from Richmond, VA on 6/25/2012

Crutchfield Customer Review (What's this?)

I don't usually write reviews, but thought this is the least I could do for these speakers. I think I did a fair amount of research online and listened to multiple sets of speakers in stores before I decided to get these P363's. Crutchfield had them at a good price per unit. These things are awesome, you never know with speakers until they are in your house set up to your receiver, but these did not dissapoint. I found that removing my sub made my system sound better after turning these speakers on. They do the job and more in place of the sub. I don't really have any sources for hd music, everything I listen to is online, and mid quality at best, so I can't attest to these and music, but I can speak to how they sound with blu-rays, and they are great. It's better then being in a theater. I was thinking of getting the polks, but the range wouldn't cover the low frequencies like these do.

Pros: sleek design, sound great, easy to hook up

Cons: none so far


SteveG from SF, California on 6/14/2012

I have owned a pair of P362s--the earlier version of the P363s--and I agree with everything said here by other reviewers. Apparently, the only differences between the P360, P361, P362, andP363 models are cosmetic. I want to emphasize that the P36x speakers have incredible imaging, producing an impressive soundstage. If you're interested, check out the Stereophile review of the P360s from 2005 (search 'Primus P360 review' and you'll find it quickly).

Pros: Imaging, articulation, well balanced

Cons: At this price, none

Solid Sound

Eddie from Atlanta, GA on 6/11/2012

Crutchfield Customer Review (What's this?)

Works great paired with the bookshelf speakers. Booming sound and deep lows. Simple cabinetry and I can see these speakers lasting a long time. Compliments my new amp nicely. You can't go wrong with Infinity. I hope to finish out with the center speaker and sub woofer.

Pros: Great sound. Simple looks.


Great Speakers

AlG from S.A., Texas on 4/9/2012

I too bought the equivalent of these back in 2005 and have been extremely pleased with them. I live on a fixed income and wanted a good sounding stereo/home theater. My son suggested these and they haven't let me down. I am still in the process off getting everything where I want it (room wise) but, I'm sure when I get it all placed where I want it I'll be quite pleased. For the money spent on these you can't go wrong.

Pros: The price and quality

Cons: None so far


Eric from Columbus, OH on 8/8/2011

These speakers are soooo nice!! i would suggest them to any one. i got these babies and i'm happy i did!! I have a friend with a $8000 home theatre set up and i hate to say this, but these speakers are better. You can put together a whole set up with these for around $1000 and blow away your friends. YOU CANT GO WRONG WITH THESE!! BUY THEM NOW!!



Pleased with performance

Tim from Philadelphia, PA on 7/30/2011

After some serious research, I purchased the equivalent of this speaker back in 2005. I have been quite pleased with these towers! I use these in conjunction with center channel speaker, a 12" sub, and two surrounds (all Infinity Primus) all tied together with an Onkyo TX-SR805 receiver. The home theater aural experience has left me literally tingling with pleasure! When I rock some Pantera or kick back with some Chopin, I use only the towers and the sub. Brilliant performance on all fronts! The clarity and bass response is nothing short of of top quality, even during the max volume test! If you're looking for some towers of power but don't want to break the bank doing so, these speakers are the answer! I've had them for 6 years and cannot justify replacing them! Thanks to Crutchfield for superb customer service and speedy delivery as always!



Pay No attention to price!!!

brel1600 from Tucson, Arizona on 7/28/2011

Crutchfield Customer Review (What's this?)

Outstanding speaker. Harman gives a lot of product for a very cheap price with these speakers. I've used other Infinity products in the past, (I have the Entra One as my PC speakers now) and they seem to be a bit brighter than these 363. Maybe a new crossover network?? Not sure but the 363 seem very detailed but not bright. One of my hobbies is audio, car and home. In short, I've been listening for a long while and these speakers are very, VERY nice. From HT to serious two channel listening. Imaging is GREAT and sound stage matches that!! You won't be sorry.



Tough To Beat By Most Measures

Rick P. from Central Illinos on 7/21/2011

Crutchfield Customer Review (What's this?)

I don't consider myself a "snooty" audiophile, but do appreciate good sounding music. I've listened to and owned a number of comparable towers from competing manufacturers, Klipsch, Polk, Yamaha etc. In my opinion, the Infinity P363's offer the best moderately priced value IF sound quality (no screaming or other in your face speaker behavior) and overall balance is important to you. The soundstaging, mid range detail and instrumental focus is outstanding. These seemed kind of harsh out of the box. Not to worry though, they really start "blooming" after about 50 hours. Go for it. You'll get great sound without breaking the bank. BTW, always deal with Crutchfield for "top shelf" service!

Infinity Primus P363

David A. from Central Illinois on 5/31/2011

Crutchfield Customer Review (What's this?)

WOW !!!! What an AWESOME set of speakers at a GREAT price. I recently purchased a set of Bose 301 speakers to attach to my vintage Pioneer stereo from the mid 70's. What a HUGE disappointment. I contacted my Crutchfield rep and asked for the best pair of speakers at about the same price. The pair of Bose were $328 and the Infinity Primus P363 were on sale at $398 a pair. The Bose were flat and had NO depth or crispness in bass. The Infinity speakers have great full range clarity and depth and you can FEEL the music!!! I HIGHLY recommend these speakers, the GREAT Crutchfield service and expertise is a GREAT Bonus. I have also purchased and LED LCD TV, Surround Sound and Blu-Ray player from Crutchfield. Thanks Crutchfield David A.

Driver Technology

Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Cascade series, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers conduct sound faster than paper, polypropylene, and Kevlar, pushing unwanted resonances beyond the operating range of the transducer. M.M.D. drivers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels.

Woofers: The dual 6-1/2" M.M.D. cone woofers offer extremely accurate midrange response for cleaner, more realistic sound. For a smoother response and improved durability, the woofers use rubber surrounds.

Midrange: The speaker has a 4" midrange driver mounted above the tweeter. Like the woofers, the midrange uses a rubber surround.

Tweeter: The speaker has a 3/4" M.M.D. dome tweeter that offers superior stiffness and damping compared to traditional metal domes.

Waveguide: The P363's tweeter utilizes an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

Crossovers: The speaker features a 3-way crossover system with crossover frequencies at 350Hz and 3300Hz. The crossover has a 24dB/octave slope.

Matching System: The P363 is voice-matched to all the speakers in the Primus line, so a complete matching system can be built.


5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Mounting Options

Outboard/Inboard Feet: The speaker comes assembled with attractive silver outboard feet. If desired, you can replace them with the supplied, less visible, black inboard feet. The feet can be changed with the use of a handheld Phillips-head screwdriver. The overall width is approximately 15/16" less, and the overall height is approximately 1/4" less when the black, inboard feet are used, compared to the outboard feet.

I've had sub woofers by Infinity & we're it not for the lightning strike my home took it would likely still work & sound great. Chose these speakers due to reputation & a diminished opinion of Polk Audio. [ Ronald  Jan 26, 2016 ]
Good name brand, Good reviews. Good price. I have a small room and these would be a great fit. [ T  Jan 21, 2016 ]

9 questions already asked

Don't know about the comparison but the quality of dialogue and conversations is great. [ SUZETTE G  Jan 03, 2016 ]
The infinity P363 has very good clarity. I would rate these as very good. I can not compare them to the speakers you own as I have never heard them in a live setting. Just take into consideration the room and acoustics of the room as that will change the sound dramatically, so the same speaker that sounds great in someone elses house may not sound as good in yours. [ matthew  Jan 03, 2016 ]
Will match a very clean mid-high blend..Just adjust P363 down a bit and ENJOY,, [ Wayne  Jan 03, 2016 ]
I Use them all the time with my tv and the sound crystal clear. I WOULD highly recommend them . [ douglas  Jan 02, 2016 ]
Your dialogue comes mostly from your center channel speaker your music and other sounds come from your front speakers but they may improve your sound although they are very good speakers [ Brian  Jan 02, 2016 ]
I am not 100% sure, about 95% sure though. They are not bi-ampable. [ JAMES K  Dec 21, 2015 ]
Made in China [ JESS  Aug 19, 2015 ]
Made in China. [ LINDA  Aug 19, 2015 ]
All Infinity Primus speakers are made in China. Don't let that stop you from buying them. The p363 sounds great for little money. [ RAYMOND  Aug 19, 2015 ]
You guessed it: China! :). But, I have to say it seems well made and it sounds good. Hope this helps. [ James  Aug 19, 2015 ]
Made in China. It is interesting that Crutchfield couldn't answer the question. I am very pleased with these cabinets. I have them in a large room (~16'x24') and they definitely do better when the volume is raised a little. To be clear, not loud-it just seems when dialed way down they are a tiny bit muddy. However, now that we have kids I rarely get time to just sit and listen to music (as an activity, not music playing in the background) as I did when younger. I would definitely buy these again. HTH.

You will need to connect you iphone to an amplifier to boost the power [ LUIS E  Aug 19, 2015 ]
You will need to connect your iPhone to an amplifier to boost the power required to run the speakers, which are GREAT by the way! [ DALE T  Feb 23, 2015 ]
No, this is only a speaker. You would need to get two speakers and an amplifier (preferably one with AirPlay so you don't have to use a cord from the phone to the amp) at the very least. There are better options if you only need to play music in one room. A quick call to one of the advisors at Crutchfield will be your best way to go. [ DAVID  Feb 23, 2015 ]
These speakers have no range I am using them for stands for my Klipsch book shelve speakers not worth buying [ BRIAN  Feb 23, 2015 ]
You will need an amp to control it and also need to buy wires. [ ANDRES  Feb 23, 2015 ]
Yes [ LUIS E  Aug 19, 2015 ]
The feet on the bottom are removable, so I would imagine they could be placed on the side instead of the bottom. Or just leave them off altogether. [ DAVID  Dec 26, 2014 ]
You can remove the feet from them, so I don't see any reason why you couldn't. [ STEPHEN B  Dec 26, 2014 ]
You probably could but if there in the air you will loose bass from them [ JEREMY S  Dec 26, 2014 ]
I don't have mine on there sides but I do believe you could do it. They are great sounding speakers. [ GREG  Dec 26, 2014 ]
Though I occasionally measure speakers for magazines, I do not know the Def Tech line. Their reputation is good. I can tell you absolutely that the Inf P362 predecessor to this model (no changes I can see) measures and sounds very good, smooth, properly balanced, accurate, with wide and consistent dispersion. It has won many blind preference comparisons and has been part of a famous and excellent speaker sound research project. (I have and have had no connection to Infinity whatsoever.) [ David  May 24, 2014 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Krissy  Apr 28, 2014 ]  Staff

Cloth [ LUIS E  Aug 19, 2015 ]
Hopefully you have the answer by I somehow missed this email. The grill is made of cloth. I bought these in July just last year....and believe it or not, just hooked them up for the 1st time yesterday. They've been in storage up until that time.....I really like Infinity. I think they build great speakers. These 363's are replacing an old pair of RS b's which I still have...... My RS b's lasted me well over 25+ years.....and I am planning on having those old Infinities re-built. I haven't even begun to Q my new 363's....I usually like to tinker around a bit and give them plenty of time to settle in before Q'ing/dialing them in....but I can already tell that these are going to be fantastic speakers. I don't understand some of the negative comments about these speakers provide plenty of it. Not to be judging others....but seriously.....I don't think those people fully understand what a full range of quality sound is supposed to sound like. These speakers flat out thump! In time they'll provide very great mid's and high's to complement the deep bass output. Hope this helped in some way. [ JOHN K  Apr 19, 2014 ]
