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.

Exclusive Infinity Metal Matrix Diaphragm drivers
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.

Speakers complete 2-year system upgrade

Written By Albert S., Sacramento, California on Monday, November 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.

Infinity Primus P363 Speakers

Written By Steve S., Central Texas on Wednesday, November 11, 2015

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

Written By Infinity primus 363 speaker, Washington on Monday, September 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

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!

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


Written By RENO58, Florida on Monday, July 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.

First speaker purchase

Written By Jacob, Crystal Lake, IL on Tuesday, July 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

Written By Fox, Wisconsin on Wednesday, June 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

Written By Eddie k, New Hampshire on Tuesday, April 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

Written By Brandon S, Illinois on Sunday, April 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.

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

Pros: Very clear, natural sound.

Cons: None.

Big Bang for the buck!

Written By Adam, Oakley CA on Monday, February 02, 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.

Written By Clarence C., Louisiana on Sunday, February 01, 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.

Big Boom

Written By Dan, West Virginia on Monday, January 05, 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

Written By Columbus John, Columbus, OH on Tuesday, December 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.

Pros: See above

Excellent speaker

Written By RWhite, Williamsburg, VA on Monday, December 01, 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.

Still going strong

Written By Michael G, Colorado on Saturday, November 08, 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.

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

Written By Kevin G, NYC on Sunday, July 06, 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.

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

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!

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.

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!

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.

Infinity Speakers

Written By Jim, Oklahoma on Thursday, January 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.

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!

Written By Jay, Massachusetts on Thursday, January 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

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.

Crutchfield Customer Review (What's this?)

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

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

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.

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

Written By AlMc, Sykesville, MD on Sunday, March 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

Written By Gino R, 10457 on Monday, March 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.

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.

Great Speakers for the Price

Written By rick4946, Dallas, Texas on Thursday, January 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!!

Written By Tim in Illinois, Channahon, IL on Friday, January 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

I called Crutchfield several times and each advisor spoke highly of these speakers. Based on this and the reviews I purchased a set to replace my aging Bose 601 Series 2 speakers. Quality packaging from Infinity and excellent fit and finish for the money spent. They sound fantastic and highly recommend these to anyone who maybe sitting on the fence.

Pros: Performed just as the advisors stated with great bass and all around superb sound quality.

Written By crownjules, Marlborough, MA on Monday, December 17, 2012

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.
