Our take on the Polk Audio TSx150C

Bring your movie soundtracks and TV shows to life

Crystal-clear dialogue. Subtle soundtrack details. Lifelike special effects that match the on-screen action. That's what you can expect with Polk Audio's TSx150C. This center channel speaker's two 5-1/4" Dynamic Balance® woofers and 1" silk/polymer dome tweeter deliver full, punchy sound for a thrilling home theater experience. And its reversible, angled-top design means you can invert the speaker for placement on a low shelf, directing the sound toward your ears for better performance. 

Designed and built for exceptional performance

Polk carefully builds their TSx-series speakers using advanced manufacturing techniques and high-quality materials — they put a lot into them so you get a lot out of them. Each one boasts Polk's exclusive Dynamic Balance® drivers — a bi-laminate design of fiber-infused polymers sandwiched together to form a strong yet highly efficient lightweight cone for natural, low-distortion sound. Polk puts these advanced drivers through extensive testing to find and eliminate resonance points, ensuring that everything you listen to sounds clean and accurate.

Polk also paid special attention to the TSx crossovers, using a high-performance design with premium parts like Mylar bypass capacitors to deliver smooth and extended high-frequency details. Even the cabinets themselves are built to sound better, using non-resonant MDF (Medium Density Fiberboard) construction to help reduce audible coloration.

Has a nice sound but not on a par with high end speakers. But for the price it is outstanding.

Driver Technology

TSx Series Loudspeaker: Introducing the TSx Series of loudspeakers from Polk; stylish and quality-built for high performance. The high efficiency TSx Series loudspeaker features a unique curved enclosure wrapped in a wood-grain vinyl. The loudspeaker employs Dynamic Balance tuned drivers and tweeters for realistic mid-range, deep, well-blended bass, and incredible detail - for a classic Polk sound that is naturally open, spacious, and clear.

High Efficiency Design: The TSx Series center-channel loudspeaker can be driven by practically any electronics, even the most modestly-powered amplifier or receiver. Whether you're connecting them to the newest digital receiver, or to your vintage amp, the TSx Series loudspeaker can produce sound that's spacious and clear, enveloping and realistic.

Dynamic Balance Drivers: The TSx Series loudspeaker uses Polk's Dynamic Balance Driver Technology for great sound. Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion. Using just the right materials enables Polk to tune out performance-robbing resonances before they occur.

Klipple Optimized Motor: Klipple Optimized Motor employs a laser and sophisticated software for large scale analysis of the TSx Series loudspeaker's drivers in motion. Using this state-of-the-art laser and software process, Polk engineers were able to optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

Silk/Polymer Dome Tweeter: The TSx150C center-channel loudspeaker features a 1.0" silk/polymer Dynamic Balance dome tweeter with a powerful neodymium magnet structure that delivers clear and detailed highs for realistic reproduction of vocals and instruments, without fatigue.

Bi-Laminate Composite Woofers: The TSx150C center-channel loudspeaker features two 5.25" bi-laminate composite Dynamic Balance drivers which are light and stiff with exceptional damping. These Dynamic Balance bi-laminate composite cone woofers use butyl rubber surrounds, polyamide voice coils, massive motor structures, and high-temperature aramid fiber spiders to create a driver of exceptionally high efficiency, clear bass, better linearity, lower distortion, and greater durability.

High Performance Crossover: The loudspeaker employs a high performance crossover system for optimum blending and time alignment of the overall speaker. Mylar bypass capacitors are used to reveal extended high frequency details.

TSx-Series Timbre-Matched: All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.

Frequency Response: The TSx150C center-channel loudspeaker has an overall frequency response of 53Hz-25kHz, while the -3dB frequency response is 63-24kHz.

Enclosure Design

Curved MDF Cabinet: The TSx150C center-channel loudspeaker utilizes a unique curved cabinet design which creates a stronger, more rigid and acoustically inert enclosure. The elegantly curved side panels, which create non-parallel surfaces, reduce unwanted internal standing waves for less audible coloration. Non-resonant all-MDF construction, with a 5/8"thick baffle, ensures cleaner, clearer, more lifelike sound quality.

Note: The TSx150C center-channel loudspeaker is available in either a black or cherry finish.

Flared Port: The TSx Series center-channel speaker features a critically-tuned, rear-firing flared port. The flared port improves air flow and minimizes port noise ("chuffing"), while ensuring good low frequency extension with low distortion. This flared port design lets the TSx speaker reveal realistic, natural, full-bodied sound with rich bass.

Anti-Diffraction Grille: The computer modeled anti-diffraction grille minimizes grille interference, so it doesn't get in the way of your sound. This black cloth grille is detachable.


Gold-Plated 5-Way Binding Posts: The TSx150C center-channel loudspeaker features gold-plated 5-way binding posts for excellent signal transfer. The 5-way binding posts will accept bare wire (up to 10AWG), pin-connectors, spade-connectors, and banana plugs (single or dual). The speaker terminals are color coded for easy identification between positive (red) and negative (black).

Mounting Options

Center Placement: The Polk TSx150C should be centered above or below your flat-panel television. Not magnetically shielded for use with older CRT televisions.

Reversible Design: If the speaker must be positioned below ear level, you can turn the cabinet upside down, allowing the drivers to fire upward.

Rubber Feet: The center-channel speaker comes with self-adhesive rubber feet so it will sit safely and securely on your speaker stand or shelf. The rubber feet add approximately 0.625" to the height of the speaker.

Wall Mounting: The TSx150C center speaker does not feature any type of wall-mount bracket or hardware. The optional PinPoint center-channel bracket (121AM15B, sold separately) can be used to wall mount the speaker.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I pick this item for the price. Plus I like the sound reproduction that Polk has. [ Julio  May 24, 2017 ]

Bought to match new Polk front mains [ STEPHEN  May 08, 2017 ]
It matches my TSx 330 front speakers. [ Samuel  May 06, 2017 ]
Brand reputation, sale price [ David  May 04, 2017 ]
Have pair of TSx330T speakers. Wanted timbre match for center channel, which my current center channel does not have. Price at Crutchfield was best anywhere, which became my incentive for buying now. Have always had great service from Crutchfield, dating back to the 70's. [ Mark  May 03, 2017 ]
Positive ratings. Markdown. Within my budget. [ Manjunath  May 01, 2017 ]
Reasonably priced center channel that will go well with the Polk Audio TSx bookshelf speakers. [ Cameron  Apr 27, 2017 ]
Polk name, price point, and positive reviews [ Alan  Jan 06, 2017 ]
Polk offers excellent audio products (they maintain a very good reputation) at very reasonable prices. This particular center speaker seems to have great reviews and will be a great upgrade to my existing center speaker and to match the Polk towers that I recently purchased (which sound incredible by the way). And this one has a discounted price as a scratch and dent! [ Andres  Dec 22, 2016 ]
I purchased this item to take advantage of the closeout price, and for the ability to flip the unit to angle up from shelf below my TV, and naturally for the Polk reputation of quality. [ Duncan  Oct 09, 2016 ]

Ordered one of these last week for my sun room t.v. set up. Enjoyed it so much ordered this one for the 75" T.V. and surround sound for the living room. Great quality sound, very crisp and level. The problem with surround sound with poor quality center speaker is volume control. This speaker handles the issue better than anything I have tried. [ Morris  Jun 18, 2016 ]
Excellent Reviews. [ Norall  Jun 07, 2016 ]

The sound is amazing! I simply gave the tech guy (Ziggy) My system I have, and he took it from there! The service Crutchfield provides is next to none! It's obvious that crutchfield hand picked the incredible tech team to help with set up, and any question's that need to be answered. Each time I have called for tech help I was given professional courtesy. Outstanding job crutchfield team!! Thank you for all your great help. Ziggy's Bio: [ jackie sue  Mar 22, 2016 ]
looks good; sounds great! [ TIM  Feb 15, 2016 ]
First time purchasing pieces to my HT system and this center speaker stood out. After a month of use, I can say I made a solid choice. I absolutely love this center piece [ Reza  Jan 26, 2016 ]

2 questions already asked

75w RMS should be quite sufficient to drive this speaker. [ CECIL W  Mar 29, 2015 ]
this should be adequate. I have a Yamaha receiver 7.2 with 75W and it drives this speaker well. I love the speaker sound. Good choice! [ Selwyn  Mar 27, 2015 ]
Hi Robert. There are no mounting brackets and it has pretty good weight. Also it has a decent amount of depth, so it'd stick out quite far from the wall. I'd imagine not. But I don't doubt your ingenuity. [ JOSHUA  Jul 01, 2014 ]
you need a shelf [ MARTIN  Jun 25, 2014 ]
There are no mounting holes or brackets on the speaker itself and it doesn't come with any mounting hardware. If you want to mount it to the wall you will have to find a special shelf or bracket to do so. Just keep in mind the depth and weight of the speaker. Hope this helps! [ JOSHUA A  Jun 24, 2014 ]
This is not mountable. However, you could put L-brackets on the wall and set this on the brackets. It is a great sounding center speaker and worth the purchase! [ LEHAN S  Jun 23, 2014 ]
I don't know because we never intended to wall mount . Tech reps at Cruchfield should know or will find out. [ WILLIAM  Jun 22, 2014 ]
