Polk's ultra-compact Blackstone TL1 proves that you don't need a big speaker to enjoy big sound. Thanks to Polk's decades of speaker-building expertise, along with some pretty advanced driver technology, you'll experience effortlessly clear sound. And if you own a flat-panel TV, the TL1's high-gloss finish will complement it perfectly.

Advanced technology produces astonishingly realistic sound
The "TL" refers to Polk's "Time Lens" technology, which aligns the drivers in such a way that all the sounds reach your ears at the same time. This improves the speaker's imaging and soundstaging, so that you'll start to forget you're watching a movie and really feel like you're part of it. An "acoustic lens" in the speaker grille disperses sound waves in a way that makes your movie and music soundtracks sound larger and more open.

The "aperiodic-tuned rear port" controls air flow in and out of the enclosure, much like a breathable membrane. It gives the TL1 the acoustic benefits of both a sealed and a ported enclosure, including better bass extension and a pleasing mid-bass boost. It also means you can place this speaker in the open or against a wall, and still get great sound.

Easy speaker placement
The TL1 has a keyhole slot in the back for easy mounting to your wall straight from the box. You can also use the threaded insert to attach it to an optional speaker bracket or stand. Create your own home theater system using a combination of black TL1s in the front of your room and white TL1 surrounds in the back. Or add a pair in either color to the TL1600 system to get even more engaging, seven-channel surround sound.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

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 TL 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.

1/2" Silk Dome Tweeter: The Polk Audio Black Stone TL1 utilizes a 1/2" silk-polymer dome tweeter for crisp, clear imaging, and smooth response that's never tiring.

2-1/2" Long-Throw Woofer: The Polk Audio Black Stone TL1 employs a 2-1/2" composite long-throw cone woofer 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.

Frequency Response: The overall frequency response is 120Hz to 22kHz and the -3dB frequency response is 135Hz to 20kHz.

Additional Speakers: The TL1 satellite speaker will require a powered subwoofer (107PSW111, sold separately) for full-range sound. You can also add addition TL1 series speakers for 2.1, 3.1, 5.1, 6.1 and 7.1 channel home theater configurations.

Enclosure Design

Enclosure Type: The Polk Audio Black Stone TL1 features a non-resonant composite enclosure with time-aligned geometry and an aperiodic-tuned rear port.

Curved Enclosure Design: The Polk Audio Black Stone TL1 satellite speaker employs 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.

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.

Aperiodic-Tuned Rear Port: An aperiodic-tuned rear port enables better blending with a subwoofer. This design combines the bass extension of an acoustic suspension enclosure with the mid-bass boost of a ported enclosure by controlling airflow through the port for better extension without distortion.

High-Gloss Finish: The Polk Audio TL1 satellite speaker features a durable, deep automotive-strength high-gloss finish that matches today's most stylish flat-panel TVs. The TL1 is available in a high-gloss black or white finish.

Connections

5-Way Binding Posts: The Polk Audio Black Stone TL1 is 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 TL1 features three integrated rubber feet so you can sit the speaker on a stand or shelf securely.

Wall Mountable: The TL1 satellite speaker feature a single keyhole slot 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 loudspeaker for mounting the speaker to the wall using an optional articulating bracket (sold separately).

Nice clean sound, I purchased 4 for a small personal training studio, provides nice clean sound with plenty of volume to crank it up during hard sessions.

Pros: Price, mounting

Cons: N/A

Great Speaker

Written By vegasrebel, Las Vegas, NV on Monday, March 16, 2015

Crutchfield Customer Review (What's this?)

Great sounding, small, easily mountable speaker for ceiling mounted surround sound. I didn't not want to have to patch and repair the gang box hole that was prewired by the builder. Every one was located next to a stud for all 6 speakers, so I utilized pin point gang box mounts with this speaker. Looks great and was very easy to install.

Pros: Small, great sound. Went with white to blend into the ceiling. Lightweight, easy to mount.

Cons: None

My Second Pair

Written By Sally, Oklahoma on Sunday, March 15, 2015

Crutchfield Customer Review (What's this?)

Just ordered two more of these speakers today. They may be small but they have big sound. I like the fact they don't take up too much space. Only gave this speaker four starts because I'm having trouble attaching them to my speaker stands. Having to go to the hardware store to get some different hardware but once I do that they will do the job. Also, the tech I talked to today was very helpful and knowledgeable.

Pros: Price and size

Cons: Difficulty connecting to my speaker stands.

Perfect!

Written By Cindy, Florida on Sunday, March 08, 2015

Crutchfield Customer Review (What's this?)

Just what I was looking for to replace and old set of large speakers. The sound quality is VERY good and the size is perfect. I keep asking myself WHY I waited so long to replace the old ones. I didn't give them 5 stars as I am just not that knowledgable about speakers.

Pros: Small size, white color, great sound and reasonable price.

Cons: None

Fits the bill

Written By RudyKazootie, Maryland on Tuesday, December 16, 2014

Crutchfield Customer Review (What's this?)

I was looking for rear speakers for my home theatre setup and these speakers filled the bill. Coupled with the Crutchfield recommended Sanus Systems HTB7 speaker stands, these speakers fit the bill. Didn't give them five stars because I don't rate anything that high.

Pros: Sound, appearance, size

Cons: None to speak of

Sweet sound

Written By SSound, Illinois on Wednesday, September 03, 2014

Crutchfield Customer Review (What's this?)

Great sound. Nice to have two satellite speaker mounting options. One warning though. I took off a star because the recessed mounting screws on the satellite speaker. IF you use DEFTECH PROMOUNT 80 speaker mounts, you are going to have to widen the hole that leads to the screw mount because of the way the promounts work. You will also have to add (lock) washers when using the promounts since the screw holes are recessed into the back of the satellite. I bought two to add to the Polk Audio Blackstone TL1600 to make it 7.1

Pros: Great sound

Cons: Be careful depending on your mounting method / hardware.

Good bookshelf speakers

Written By SteveD, Elkhart, IN on Tuesday, September 02, 2014

Crutchfield Customer Review (What's this?)

I have been very happy with these as the left and right front channels of a 5.1 surround system. The fit nicely in our built in shelving and are attractive. Their sound is clear with good dynamic range. I recommend them.

Pros: Good clarity Small size Attractive

Cons: Cannot find any yet

Excellent Speaker - Small Package

Written By DavidS, Tryon, NC on Wednesday, August 27, 2014

Crutchfield Customer Review (What's this?)

I was looking for a small speaker to sit on our mantle and replace our front speakers on our surround system. These work perfectly and sound much more crisp than our in-wall speakers.

Pros: Very small with clean crisp sound.

Cons: Really none.

AMAZED!

Written By JPGTI337, DALLAS,TEXAS on Thursday, August 14, 2014

Crutchfield Customer Review (What's this?)

I was so amazed with these speakers! I ordered one pair to replace the old blown Philips surround sound speakers I had. WOW! The clarity and volume these little guy produce for the price is unbelievable. Now I will have to buy another pair to replace the other two old speakers as these over power the old ones lol.

Pros: Clarity and Quality for price!

Cons: None that I can see at this point, have owned only for 6weeks.

Fantastic Speakers!

Written By Fran, Toms River, NJ on Sunday, July 27, 2014

Crutchfield Customer Review (What's this?)

I purchased 2 of these speakers after receiving advice from Crutchfield rep (Dylan)....he was absolutely right, I an older stereo system that had HUGE speakers which finally broke. These bookshelf speakers are the best sounding and perfect fit for my stereo system. I would absolutely trust a Crutchfield Rep to recommend another system or unit to me in the future. The sound, quality everything made this purchase worth the price! I so recommend anyone thinking about purchasing these speakers to do so or if my recommendation isn't enough, speak with one of the Crutchfield people -they know their stuff.

Pros: Excellent sound quality, can be placed anywhere and are small enough that they won't be noticed.

Cons: None

A remarkable small speaker

Written By Smerdyakov, Virginia Beach on Friday, May 16, 2014

Crutchfield Customer Review (What's this?)

My experience with audio products goes back to the early '60s, when speakers were judged by size and weight - the bigger and heavier, the better. Time and technology have rendered that method of assessing performance irrelevant, as is demonstrated by this small speaker. When one takes one out of its box, one's feeling is that fine performance from such a small unit will be impossible, but that is wrong - it worms very well. I had been trying to improve the performance of the side surround channel in my system, and had tried several different speakers that I had on hand, without getting the effect that I wanted. I decided to try the TL1s, since they had received good reviews, and were modestly priced. I am very glad that I did, since I achieved exactly what I had not been able to do previously: the high frequency response and presence of my side channels has been considerably improved.

Pros: Excellent presence and frequency high frequency reproduction

Cons: Best used with a subwoofer

Polk Audio BlackstoneT TL1

Written By jlaw, Adrian, MI on Tuesday, June 25, 2013

Crutchfield Customer Review (What's this?)

Great value. I'm using these as surround speakers; however when they arrived I auditioned them as main speakers (with Dyna Audio Sub). Fantastic sound right out of the box. They opened up even more after a couple days of break in. the sound stage is open and wide, liquid midrange and non-fatiguing trebble. Clear open sound. Unfortunately, there is ZERO useful bass. Even though there was a sub, there was a noticeable gap in the midbass. I didn't play around with the low pass x-over on the sub; that probably would have helped. Forget about using these alone though. They remind me of NHT Super Zero's from the 90's...only better!

Pros: Excellent sound quality, Fantastic value, attractive

Cons: No bass

Exactly what I needed

Written By Douglas, Yorba Linda, CA on Saturday, April 13, 2013

Crutchfield Customer Review (What's this?)

I already had a 5.1 Polk Blackstone 1600 speaker setup but wanted to add two more speakers for "height" in my 7.1 configuration. I could not find these speakers at any local store and one place wanted $20 more each than Crutchfield. The speakers are great, I already knew that. The ease of ordering from Crutchfield was amazing. They arrived exactly when promised, well protected in their original boxes and placed into a larger box with plenty of packing peanuts to prevent any shipping damage. I'm sold on Crutchfield.

Pros: Small speaker / BIG sound. Great product. Have not been disappointed

Amazed

Written By SteveM, Atlanta, GA on Monday, October 22, 2012

Crutchfield Customer Review (What's this?)

I'm amazed at how much rich sound comes out of these little speakers. It's like i've been missing out on everything I was listening to prior to this purchase. i'm on a budget, but was in serious need of a new system for my small house in the city. I paired these up with an Onkyo TX-8255 receiver, and a Polk PSW-108 powered sub. I've barely watched television since the purchase. If you're on a budget, or don't have a ton of space but want great quality sound, these would be a smart purchase.

Pros: quality, size, appearance

Cons: No low frequency (but these are bookshelf speakers).

TL1

Written By Smooth, Seattle WA on Saturday, October 13, 2012

Crutchfield Customer Review (What's this?)

Used as surround speakers on a 5.1 system @ 100w/ch crossed over at 120hz. These TL1s are smooth on the highs. When I read reviews I look for someone to mention whether a speaker is harsh on the highs or not and these are very comfortable on the ears. For what it's worth, i think these are better voice matched to my monitor 70s than were the monitor 30s they replaced. I'm extremely pleased with these as surrounds- 5 stars for the class they're in. Beautiful white finish and are clean looking on a white wall. Bottom line: they sound great for being 2.5" drivers.

Pros: Size, fit and finish, sound quality, mounting options, made by PolkAudio!

Cons: For my preference you would definitely need to match this with a subwoofer.

Bought these when i ordered my TV for two reasons 1. Ive been looking for new

bought together with my TV i save $$. Wow these things are really crisp, great
sound at all volumes. Not much mid bass but its cool because im using them as
surround speakers. Highly recommended o_O
