Our take on the Polk Audio Blackstone™ TL350

High-performance sound from compact, elegant speakers

Build the home theater system you always wanted without sacrificing valuable living space. Polk's Blackstone TL350 system delivers lifelike performance from handsome, compact speakers. The TL350 contains four perfectly matched Blackstone TL3 satellite speakers and a Blackstone TL3 center channel speaker. Built using the same tweeter design found in their flagship full-sized loudspeakers and packed with exclusive state-of-the-art technologies, the TL350 speakers overcome some of the usual limitations of compact speakers. You'll hear the kind of accuracy and detail you expect from much larger speakers, including a wide soundstage and realistic detail.


Crisp, dynamic sound thanks to high-tech drivers

grille off

A big part of the TL350's incredible sound is the 3/4" Ring Radiator tweeter in each of the five speakers. Found in Polk's flagship speakers, these sophisticated tweeters reproduce transparent, natural highs. The 3-1/4" aerated polypropylene woofers are lightweight, but also stiff and strong, allowing the cones to move more freely in the baffle. It means you can play your movies and music loud without hearing any distortion. Polk's Extended Linear Motion voice coils help make the cones' movement even more efficient to further cut down on distortion and extend the speakers' dynamic range. This increased efficiency is the key to the TL350's big sound.

Immersive home theater performance

The "TL" refers to Polk's "Time Lens" technology, which aligns the drivers in such a way that high- and low-frequency sounds all reach your ears at the same time. This improves the speakers' imaging and soundstaging, so that you'll feel less like you're watching a movie and more like you're part of it. An "acoustic lens" in the speaker grilles disperses sound waves in a way that makes your music and movie soundtracks sound larger and more open. The TL350 also features Polk's acclaimed PowerPort® technology to help reinforce bass output. Plus, its sturdy cabinets are reinforced with steel plates to help fight resonances that can muddy the sound.

Easy placement and optional system customization

The TL350 speakers have combination keyhole slots and threaded inserts in the back for easy mounting on your wall. Complete this system by adding the Polk powered subwoofer of your choice to get deep, room-shaking bass. You can even upgrade to a seven-channel home theater when you add an extra pair of satellite speakers to the mix.

sound really good in music and move, but a real good subwoofer is a must.I hooked them to 308 Bower & Wilking subwoofer and a THX Onkyo receiver model TX-NR 117. They sound awesome.

Great speakers without a subwoofer.

Polk audio Blacstone TL350. from Miami, FL on 9/23/2016

Crutchfield Customer Review (What's this?)

sound really good in music and move, but a real good subwoofer is a must.I hooked them to 308 Bower & Wilking subwoofer and a THX Onkyo receiver model TX-NR 117. They sound awesome.

Pros: These system Kicked out my quintet v Klipsch system which sounded muddy in music.

Cons: Too expensive (considering the subwoofer is not included in the package & they have been designed to work with a subwoofer.)

Great sound for such a compact size

Josh from Severna Park, MD on 1/18/2016

Crutchfield Customer Review (What's this?)

Compact size mounted on the ceiling keeps them out of the way and above the kids reach. Awesome sound paired with 8" Polk compact sub.

Pros: Size, sound, cosmetic appearance

Cons: You will need a sub woofer but you should have one anyway even with larger speakers.

PeteKaz from Georgia on 12/27/2015

Crutchfield Customer Review (What's this?)

Good speaker for small and medium size rooms. This will we good for 95% of the people who purchase them. Need a sub with these but I am sure everyone would know that. Clear sounding.

Pros: Clear crisp sound

Cons: Lacking on the low end

good things in small package

JMG from Florida on 12/7/2015

Crutchfield Customer Review (What's this?)

Only had these about a week. I like their crisp clean sound (without any tinniness). Might give it 5 stars after more time with these, but for now I'm just not sure yet. Paired with the Pro 440wi sub - a great match.

Pros: clean sound, small footprint

Cons: a challenge to mount on speaker stands - hard to mount with its solid rear rubber pad, but only a single point on front.

I love these speakers

mj from Suffolk, VA on 5/20/2015

Tim H. from Cleveland, OH on 1/18/2015

Crutchfield Customer Review (What's this?)

I have to say that I am Amazed at how Crystal clear, loud and the depth of the sound these lil guys produce. I have them paired with a PSW-125 12" powered sub and a Pioneer VSX-522 in a 12'x14' room...Rattles the windows and Rocks the house!

Pros: Size, clarity and ear piercing highs!

Cons: Definitely need a powered sub!

Very Pleased

Matt from Washington on 12/27/2014

Crutchfield Customer Review (What's this?)

Very pleased with overall size and performance of these speakers. Paired them with a Polk DSW Pro 550Wi and they fill the room nicely. Was worried that due to their size, I would lose a lot of the midrange but so far I haven't noticed that being an issue.

Pros: Smaller size speakers, less obtrusive in the room.

Cons: Drivers are on the smaller side, but that's to be expected with compact/satellite speakers.

RAK from St. Louis MO on 6/20/2014

Crutchfield Customer Review (What's this?)

Bought the Polk Audio TL350's when my Bose Lifestyle system started giving me trouble. Been a Bose man for years. Hooked these up to the Denon I also purchased at Crutchfield and they blew my old Bose system away. Also included a DSW pro 440 subwoofer with them for my 5.1 setup. Easy setup great sound. They are perfect for my small livingroom 12x17 . Clean realistic high end low full Bass sound not boomy but you can feel it in your gut. So far I have used them mostly for music but they sound great with my Bluray movies also Highly recommended for serious music lovers.

Pros: Crutchfield was great. Easy hookup.

Cons: None yet

Crutchfield Customer Review (What's this?)

Pared these with a Onkyo 727 and a Polk audio dsw 400wi sub. I have calibrated the setup twice and have been very pleased with the overall sound. As of yet haven't played a bd movie but movies played from the cable have been awesome. I'm not a sound expert but these put out a great surround sound in my home.

Pros: good overall range.

Cons: none so far


Rey from North Charleston, SC on 2/5/2014

Paired these bad boys with a Polk Audio PSW505 sub and am powering them with an NAD T757 AVR. Best sounding system I have owned! These speakers are very dynamic for their size. Movies take on a whole new dimension. Music seems to just fill the room. The speakers themselves seem to disappear. I have been going back through my blu-rays and even DVD's and watching them again. Each one offers something new, sound wise. Everything you feed these things turns into audio gold. The sound is very three-dimensional and life-like. I was debating between these and the Definitive Technology Pro Cinema 800's. I asked Chuck about the two and he said "To me, the Polk speakers have a slightly more dynamic sound, especially with music, but that's just me". That was all I needed. I love Crutchfield and this is one of the reasons why. Their customer-friendly staff is second to none. Thanks Chuck. Thanks Bill (for hiring Chuck).

Pros: Very dynamic. Almost invisible. 3D sound field.

Cons: I bought them in white, except the center channel. It's not available in white. Would have preferred white.

Amazing Sound!

R from Glendora, CA on 12/26/2013

Crutchfield Customer Review (What's this?)

Not a whole lot to say. These speakers sound great! We purchased to use in a small home theater for watching movies and listening to music. Sound is crystal clear for both applications. The one thing I'd like to see is for the supplied mounting brackets to allow tilting the speakers down a bit.

Pros: Crystal clear sound Nice looking

Cons: Supplied mounting brackets do not allow tilting of the speakers up and down. Side to side alignment adjustment is provided.

Great speakers

timmy2high from Des Moines, WA on 3/9/2013

Crutchfield Customer Review (What's this?)

These aren't the cheapest set of surround speakers out there, but they sound great. I had to replace my old RT800i/CS400i/RT35 'vintage' Polk speakers (due to downsizing considerations only), and dare I say these sound even better. Obviously, a subwoofer is a must have when using satellite sized speakers, went with the DSW440 since I have a small condo and was trying to keep the overall size of the sub as small as possible. Extremely pleased with the setup and the sound. Build quality superb. You get what you pay for!

Pros: Great balanced sound for a small speaker package. Quality construction.

Cons: None - if these fit your budget.


Steve from Mandan, ND on 3/8/2013

Crutchfield Customer Review (What's this?)

I orderd these with two extra speakers and hooked up to an Anthem MRX 500 audio video receiver they are outstanding. Very crisp I also ordered the Polk PSW 660 subwoofer. This is an awesome setup!

Pros: small, compact, heavy, crisp and very cool looking

Cons: my calibration mic thinks these are big speakers, so i did set the cross over at 120 mhz. Not really the speakers' fault.

Great sound

LG from Ann Arbor, MI on 2/28/2013

Crutchfield Customer Review (What's this?)

Easy to set up and great crisp and clear sound.

Pros: Look is shinny black, sound quality for TV and movies is great, easy to put on stand or wall

Cons: Thinner would be nice

Great Looking & Sounding Speakers

Jim from Wallkill, NY on 2/28/2013

Crutchfield Customer Review (What's this?)

These are fantastic "decor friendly" speakers. Spectacular sound on a 5.1 channel home theater system in a great looking package that blends in with any room decor. Have the front speakers sitting on each side of a 55" plasma on a credenza with the center channel speaker on a shelf under the TV. Rear speakers on wall mounts at the rear of the room (14' X 20'). Great crisp theater quality sound for that size room - great match with the PSW-111 that was part of a special deal at the time. Speakers are sonically well balanced and with the receiver set up properly the front and rear channel speakers work beautifully together. Also sound reasonably well with music due to the fact that the PSW-111 doesn't overpower the smaller speakers. All in all a beautiful package. Not the cheapest 5 pack around, but in my opinion worth the price.

Pros: Great sound, great looking

Cons: Wish the 5 pack had been available in white

O.K. at best

cmg1121 from Oxford, CT on 2/22/2013

Crutchfield Customer Review (What's this?)

They sound O.K. Replaced my 2005 surround sattelite speakers Polk RM series which I liked. They had lived their life! Don't really recall what I paid at the time but this price doesn't ring a bell. The center channel on the tl350 is very small forcing me to put it on the wall under the t.v. Not what I wanted to do. The sound O.K. I have some tweeking to do. I haven't calibrated the Onkyo receiver that I purchased from Crutchfield yet. The only thing that makes it almost worth the price is that it came with the sub woffer, that I don't need. But I took it. I have two PSW10 from 2005 and they work great still so leaving them. Maybee sell the PSW111 on line cheap! Three stars for price vs. quality. Not worth the price. Sorry other reviewers. I got a set of Polk satellite speakers from 2006 for my master bed room and they are just as good as the tl350. Not overly impressed.

Pros: Nice black color, matches tv and everything else but cable box!

Cons: price vs. quality not worth more the price even with subwoffer.

Excellent product/ Outstanding Service

Mike from ALexandria, MN on 1/22/2013

Crutchfield Customer Review (What's this?)

I love these speakers, they put to shame my old speakers. And the free Sub is great. I couldn't be happier with my purchase. Crutchfield really knows how to stand out as a #1 online retailer.

Pros: Shipping and delivery times are 2nd to NONE!

Cons: none

Great Small Home Theater Speakers

BrianP from Kentucky on 1/11/2013

Crutchfield Customer Review (What's this?)

I used this speaker set to replace an all-in-one Samsung system. I partnered these with the upgrade Polk sub 660 and a new Pioneer SC-61 (purchased seperately). After two weeks with these speakers and other components, I am extremely pleased. The Polk TL350's provide great dynamic range in a small man-cave, 15X15. I would recommend these to anyone who is starting out, especially with the Polk sub upgrades.

Pros: Easy setup. I already had stands for the front and rear speakers. You can use bare wire or banana plugs.

Cons: None at this time.

Awesome little speakers

Lovin it from Rock Hill, SC on 12/28/2012

Crutchfield Customer Review (What's this?)

I got these speakers to replace some Bose 5 speakers that I got from a friend a few years ago. These speakers blow the Bose speakers away. Couldn't be happier. Price comparison with the Bose speakers was close but the audio quality is far superior.

Pros: Size, styling, sound

Cons: Mounts difficult to find

Excellent sound and clarity

JasonB from San Diego, CA on 11/23/2012

Crutchfield Customer Review (What's this?)

Sound is amazing from these speakers. I tried two other home theater systems before this one, and there is no comparison. Paired with Denon 1613 receiver and Klipsch SW-112 sub.



the best of its kind...

the clarity of sound from these little speakers is superb... money well spent. you won't go wrong with this one. highly recommended.




JoeCT from CT, USA on 10/24/2012

Crutchfield Customer Review (What's this?)

This product is perfect for my needs. My apartment is 1000sq ft detached from the main house (key factor here is I don't share any walls with anyone). I paired this speaker setup with a Marantz A/V receiver (model NR1603) and the Polk Audio DSW Pro440 subwoofer. Excellent product producing great sound for both music and movies.



Impressive Home Theater Sound

Teng from Saipan, MP on 9/18/2012

Crutchfield Customer Review (What's this?)

We know we can't hear big sound out of small speakers, but the Polk's tag line "Big Speaker Sound Without The Big Speaker" really caught my husband's attention. And the TL350 did not fail to impress us because the sound quality is really amazing. But to unleash the beast, you need to have a good receiver. It matches well with DSW Pro 440 subwoofer. Thanks to Crutchfield for fast shipping.



Polk TL350 are awesome

CPK from San Jose, CA on 3/11/2012

Crutchfield Customer Review (What's this?)

I am amazed by the clarity of the speakers. My room is 12 by 18 ft and both the music and movies sound excellent. I am discovering notes in the music that I never knew they existed. The speakers are small and blend in well with the aesthetics of the room (I have black color speakers). Make sure you get a good receiver to complement these speakers. Net Net - excellent buy. My setup is 5.1 all TL350 and Polk sub-woofer. I paid $750 (center + 4 speakers) and got the woofer free as part of the deal from crutchfield. Now we enjoy movies at home with Blu Ray and show-off to our friends :) Neighbors are cool too.... thought I share as reviews from other folks have helped me as well - keep sharing and

Pros: Excellent sound, blends in well with the room - I have the rears mounted on the ceiling

Cons: It may be costly - but my experience is that it is worth every penny. I have had them for little over a month.

Amazing small speakers... lives up to reviews!

UFgolfer from North Palm Beach, FL on 2/11/2012

Crutchfield Customer Review (What's this?)

I've had the TL350 for almost three months now, and for an apartment system, these speakers are amazing! I matched the TL3 speakers with a DSW Pro 550wi sub-woofer and Pioneer VSX-1121 receiver and they have proven to be good purchases as well. Not being an audiophile, I was very anxious about buying a home theater system without hearing them first, but to my relief and pleasure, they have lived up to the reviews by others on this site and other websites. I highly recommend for someone looking to use these in a small setting.

Pros: Great looks, excellent clear sound, fits nicely in my living room.

EJR from Friendsville, MD on 1/23/2012

Very happy with the sound and looks of the Polk TL350. Would recommend for crisp sound, quality built, and system price. Matched with the Polk DSW550 subwoofer and a Yamaha RXA2000 Home Theater Receiver and am very pleased.

Pros: Great sound and quality for the price.

Cons: None

Nice sound

Ted from Tampa bay, FL on 1/19/2012

Crutchfield Customer Review (What's this?)

Center speaker fit prefect under the 61" plasma which is not wall mounted. Sound is clear with movie and sound on the Denon1912 and the Polk 550wi. Very pleased. Was cooncerned the local big box stores only had the intro models, but I think it is because this would eat into their higher profit speaker deals. Dunno. But I do know I am happy

Pros: Small size with clear sound. Very happy with movies

Cons: Cherry might have been nice as another option

Crisp and clean!

Spanky from N.Y. on 12/13/2011

An upgrade from my Bose Acousticmass 10. Much crisper sound. Great highs, lows and mid range. I got a free sub. I upgraded to the DSW440. Great match! Highly recommended! Great clear center channel that stands out.

Pros: Clean, crisp sound.

Cons: N/a

Amazing Sound quality

ArianM from Baltimore, MD on 11/24/2011

Crutchfield Customer Review (What's this?)

Just bought this product from Crutchfield about a week now, was looking at these way before they were released. When Crutchfield had a promotion to get a free sub I decided that I'm going to buy it. Anyway these speakers are just awesome, the sound quality is crazy good, you hear suff that you never knew exsited in music. movies, and even video games. The tweeters are not to harsh but reveal so much detail in what ever you listen to. I also bought a Pioneer VSX921-K reciever to go with these speakers and it just blew me away. Very excellent product from Polk audio no regrets and will recommend this product to anyone who wants an excellent sound system.

Pros: Excellent product, detailed sound especially because of the ring radiator tweeters, nicely built enclosures, and just totally awesome.


Polk Audio TL350 5-Speaker Set

Volkster23 from Upstate NY on 9/11/2011

Crutchfield Customer Review (What's this?)

Well I held out as long as possible to switch to Satellite speakers. I was so worried about giving up that deep roomy sound from full sized speakers. I had Paradigm 9se MKII fronts that I have had for 20 years which were amazing. Anyway, after a week with the new Polk's hooked up to my Denon AVR1912 along with my orginal Paradigm PS1000 10" sub, I am blown away! I do recommend that a sub is a must for the perfect "full" sound. I currently have the crossover frequency set at 100 htz which seems to be the sweet spot. I've listened to several Blu-ray movies including Transformers and several types of music including Metal and Pop (lots of digital sounds) at high volume levels. I can't believe these little speakers can produce such good sound especially at higher volume levels. I opted for the TL350's over the 250's because I was afraid of giving up too much quality sound. Not sure how the 250's would have sounded but you WON'T be disappointed with the 350's. The sound will only get better as they break in. One more note, I called Crutchfield and Polk Audio with questions prior to the purchase and both have top-of-the-line customer service. I hope this helps those holding out like I was.....Place your order for them at Crutchfied now!



Polk TL 350

Jamkel4 from Pensacola FL on 9/1/2011

Crutchfield Customer Review (What's this?)

The TL 350 sounds great. I spent a significant amount of time researching home theatre sound systems. I'm very glad that I purchased the TL 350 instead of a competing Bose system displayed at the local big box electronics store. It's hard to purchase speakers that you've never heard but you won't be disapointed by the Polk TL 350 system. No local electronic stores sold the TL 350 so I was forced to make a buying decision based on both amature and professional reviews. This system delivers Crystal clear sound from the speakers at high volumes. Music sounds just as good as a Blue Ray movie. The relatively small and attractively styled speakers blend in well with the television and living room. The music fills my entire 2300 square foot house. I chose the Polk DSW 550 WI sub and it makes for a superb home theatre system. I hope you choose the Polk TL 350 and enjoy them as much as I have.



Mind-Blowing AMAZING Clarity

dhp from North Attleboro, MA on 8/23/2011

Crutchfield Customer Review (What's this?)

Let me be the one of the initial proud rater of these mind blowing speakers. I was researching since last few months on what speaker set to buy under 1k budget. I read good review about Tl250, but almost no reviews for TL350. Though I read about it using nice driver and ring radiator tweeter.Couldnt resist deal from Crutchfield and bought it. I set TL350 set with Denon AVR-2112 and Polk DSW-pro550 wireless SW connected via 16-g speaker wire. I listened wireless AirPlay i-tunes from my laptop, and I heard things i never before ! AMAZING superb clarity of sound with very detailed, balanced and warm blend of sound ! Low and at very high volume, above quality remained as it is no change in clarity, detailed balancing, warm blend. Listened to rock, hiphop, classical, jazz, instrumental and still same result. Listened on Pandora / CD/ USB and all diffrent sources, still amazing same result ! Next turn was for movies, saw Avatar, Troy, Lionking, Transformer and WOW i felt myself in the movie, room was filled by rich, crisp, clear sound. very clear dialogues , all midrange clarity along with very crisp clear high range sound, and room shacking low range ! Speakers are heavy 3.75 lb and very solid built, it needs heavy duty good quality mounts or stand. Crutch-filed service is awesome , I got the delivery in 2 days ! Happy speaker hunting and listening.

Note: The Black Stone TL350 has an overall system frequency response of 115 to 28,000 Hz and will require a powered subwoofer (107PSW111, sold separately) for full-range sound. You can also add addition TL3 series speakers for 6.1 and 7.1 channel home theater configurations.

Driver Technology

Dynamic Balance Driver Technology: Polk Audio's patented Dynamic Balance process allows Polk to design their drivers specifically for flatter frequency response, revealing the sharpest details and a more lifelike transparency, with absolutely no strain even at high volume. It's a bold, rich, warm, and lifelike sound.

Time Lens Technology: The sophisticated laser alignment of the "acoustic center" of the Blackstone TL3 tweeters with their accompanying drivers results in far superior imaging. The acoustic centers of the tweeter and mid-range woofer are aligned, creating a crisp accurate soundstage. The acoustic centers of the tweeter and mid-bass driver are located in the same plane for superior imaging, while the acoustic lens incorporated in the grille smoothes the tweeter's frequency response.

3/4" Ring Radiator Tweeter: The Polk Audio Black Stone TL3 series speakers feature a 3/4" ring radiator tweeter that is normally found only on high-end loudspeakers. The 3/4" ring radiator tweeter offers incredible accuracy and detail, so you music sound likes the artist intended.

3-1/4" Aerated Polypropylene Woofer: The Polk Audio Black Stone TL3 series speakers employ a 3-1/4" aerated polypropylene cone woofers with Dynamic Balance driver technology (Polk's patented transducer design process) that produces a flat frequency response, with sharp detail, transparency, and the ability to play loud without strain. The aerated  polypropylene cone is lightweight, yet stiff and strong, with longer linear excursion capabilities in a limited compact enclosure space, so it plays louder with less distortion.

Note: Each satellite speaker features one 3-1/4" woofer. The center-channel speaker features two 3-1/4" woofers.

Optimized Linear Motor Structure: Engineered for better compact speaker performance, Polk's OLM Motor Structure flattens the BL Curve, making cone movement more efficient than previously possible, reducing distortion and extending the small speaker's dynamic range right up into big speaker territory

Frequency Response: The system's overall frequency response is 90-31,000Hz, and the -3dB frequency response is 115-28,000Hz.

Enclosure Design

Enclosure Type: The Polk Audio Black Stone TL3 series speakers feature a non-resonant composite enclosure with time-aligned geometry, and PowerPort technology.

Curved Enclosure Design: The Polk Audio Black Stone TL3 speakers employ non-parallel surfaces that not only lead to a stronger, more rigid and acoustically inert enclosure, but they also result in less audible coloration from internal surface resonances.

Steel Reinforced: Extra-rigid steel plates reinforce the curved enclosures of the TL3 series speakers, resulting in acoustically inert enclosures free from internal resonances and any audible coloration, for more lifelike audio detail.

Integrated Acoustic Lens: An innovative acoustic lens incorporated into the grille produces a high frequency response so smooth that it delivers a balanced, realistic performance. An acoustic lens is molded into the back of the speaker grille and helps create imaging frequency balance previously impossible in small high-performance satellite speakers.

PowerPort: The Polk Audio Black Stone TL3 series speakers utilize Polk Audio's patented bass venting technology, for added midbass response and increased efficiency. PowerPort technology decreases port turbulence and virtually eliminates "port noise," for a massive 3dB boost in bass response.

High-Gloss Finish: The Polk Audio TL3 series speakers feature a durable, deep automotive-strength high-gloss black finish that matches today's most stylish flat-panel TVs.


5-Way Binding Posts: The Polk Audio Black Stone TL3 series speakers are equipped with one pair of 5-way binding posts to ensure a secure connection to many types of speaker cables and connectors. The binding post terminals will accept banana plugs (single or dual), pin-connectors, spade-connectors, and bare wire (18-12 AGW).

Mounting Options

Rubber Feet: The Polk Audio TL3 speakers feature integrated rubber feet so you can sit the speakers on a stand or shelf securely.

Wall Mountable: The Black Stone TL3 satellite speakers and center-channel speaker are wall mountable.

  • Satellite Speakers: The TL3 satellite speakers come with wall-mount brackets that feature keyhole slots. The included wall-mount brackets attach to the speakers' 1/2"-20 threaded inserts. The keyhole slots let you mount the speakers to a wall with a single mounting screw (not supplied). You can angle the speakers left or right by adjusting the brackets position on the back of the speakers. The 1/4"-20 threaded inserts on the back of the satellite speakers can also be used for mounting the speakers to the wall using optional articulating brackets (sold separately).
  • Center-Channel Speaker: The TL3 center-channel speaker features dual single keyhole slots on the back of the cabinet for wall-mounting the speaker without any additional wall-mount bracket (mounting screws not supplied). There is also a 1/4"-20 threaded insert on the back of the center-channel speaker for mounting the speaker to the wall using an optional articulating bracket (sold separately).

Exceptional surround sound

Written by Allen, Advisor, on 2/5/2014 6:18:00 PM

What really helps the Polk Audio TL350 surround sound system stand out is the Ring Radiator tweeter which Polk also uses on their top of the line LSI speakers. The TL350's offer outstanding mid-range detail and the highs are extremely accurate.

I was particularly impressed in the stellar voice quality and clarity that the center channel provides. For such a small speaker, sound dispersion is also impressive. This alone would be an excellent center channel choice for most surround sound systems as it has a very natural sound that would match up very well with most speaker brands.

With these speakers you will need a subwoofer, or larger main speakers to compliment and give you full tonal balance. I've been using the Polk Audio's DSW Pro 660 and while that is a powerhouse of a subwoofer, it does not overwhelm the TL350's as they keep up amazingly well.

Overall, I've been extremely happy with the setup in terms of surround sound. During music listening in 2-channel stereo I do miss the broadness and robustness of larger main speakers, however. So if you listen to a lot of music as well as watch movies, you may want to consider adding in some bigger mains to complement this system. If not concerned with that, then the Polk Audio TL350 system easily offers some of the best surround speakers for the money.

Why did you buy this?

wanted a compact solution. I have had good luck with Polk. I wanted the better connection posts. [ Clifford  Sep 05, 2016 ]
we have Polk Audio speakers in our upstairs bonus room and they sound great. The price reduction helped me to make this purchase. [ Susan  Aug 23, 2016 ]
Price and reviews [ BRIAN  Aug 08, 2016 ]
First of all Crutchfield is a good reputation website, with 60 days returning products,and secondly I red many positive customer reviews & finally the day I purchased it, The unopened & brand new TL350 Polk audio speaker system was sold out ;so that I purchased the scratch and dent for a chipper price. [ fernando  Feb 13, 2016 ]
These have been some of the best speakers I have owned. I have bought a more expensive set for another room a year prior to this set. I honestly think Polk has outdone themselves on this system. Excellent buy for the money. Make no mistake: these are heavy speakers with a very solid sound. Highly recommended. [ ALEX  Feb 02, 2016 ]
Premium sound for my smaller media room without compromises. The special offer on the subwoofer sealed the deal! [ George  Jan 27, 2016 ]
Great speakers.... [ Jeff  Dec 18, 2015 ]

3 questions already asked

Yes, you can if your receiver will support a 7.1 format. When I initially purchased the TL3 speakers, I was using two similar (Cambridge Soundworks) speakers which, eventually, were replaced by two new TL3 speakers. The speakers are matched in such a way that they work well together. [ Dr.  Dec 24, 2015 ]
Yeah you can check the system details on the website for TL350 to match. [ CORDELL  Dec 24, 2015 ]
I have the 350s as a 5.1 and totally happy driven by an onkyo nr-828 but if the receiver supports 7.1, no reason you cant add 2 more. [ NICK  Dec 24, 2015 ]
99.9% sure. When I bought my TL350 over the phone with Crutchfid, they told me it was 4 TL3 speakers with the matched center channel. Same thing, just put as a set. Adding 2 TL3s to the TL350 would make 4 matched speakers (plus center). I added a sub and everything sounded amazing. When in doubt...just call them. They will explain everything. I always call before a purchase, even if I know exactly what I want....just to make sure I did not overlook something. [ JEFF  Dec 24, 2015 ]
Yes, that's what I did. They sound great in my family room. [ Earl  Dec 24, 2015 ]
These speakers will mount directly to the wall with no additional mounts. They are small so I think any stand will work with them if you are not mounting them [ ROBERT J  Apr 01, 2015 ]
I bought sanus stands and ultimately ended up using the factory stands. They were definitely strong enough but I honestly did not like the way they looked and I ended up returning them. I have not had any issues with the factory stands. [ JOSHUA  Apr 01, 2015 ]
Any stands that you try to mount with speakers are not strong enough. I tried two different brands of stands and they both fell over. Try velcro mounting them to a wooden stand with a flat surface. It works but the look I don't like because the speakers have a small base and the speaker stands surface is large 8 x 8. Hope this helps. [ DWIGHT  Apr 01, 2015 ]
The shipping weight for the five speakers is 20.3 lbs. The center speaker weighs 4.7 lbs. Therefore, the satellite speakers weigh approximately 3.9 lbs each. [ RICHARD A  Dec 07, 2014 ]
Robert, I remember them being heavy, but they are hanging on the wall, so checking that is not an option. I did, however, find a system review online, which states that each of the satellite TL3 speakers is 3 pounds, while center speaker is 4.7 pounds. Hope this helps. By the way, they are excellent speakers for the price! Don't forget one of their subs, which are phenomenal. [ ALEX  Dec 07, 2014 ]
They come with adjustable mounts that keep them tight to the wall for a nice low profile [ ROBERT J  Dec 07, 2014 ]
I don't know the exact weight but they are definitely less than 8 pounds each. Great system! You will not be disappointed. [ BRYAN  Dec 07, 2014 ]
No worry. They're only a couple-few pounds each. [ WILLIAM R  Dec 07, 2014 ]
