Our take on the Polk Audio TSx250C

by Dave Bar
Polk Audio

Your home theater's most important speaker

The center channel speaker is the workhorse in a home theater system. It has to reproduce clear dialogue and special effects that keep your eyes and ears glued to the movie action. A high-quality center speaker is a great investment for any surround sound setup. Try to choose one that's as closely matched as possible to your front right and left speakers, so that as sound moves across the front stage, it stays seamlessly realistic.

Dynamic center-channel sound

From the softest whisper to the loudest explosion, Polk Audio's TSx250C center channel speaker gives you the detail and clarity you need for lifelike home theater realism. This center channel speaker's two 6-1/2" Dynamic Balance® woofers and 1" silk/polymer dome tweeter deliver powerful sound that puts you right in the middle of the on-screen action. 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.

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 TSx250C 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 TSx250C center-channel loudspeaker features two 6.5" 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 TSx250C center-channel loudspeaker has an overall frequency response of 48Hz-25kHz, while the -3dB frequency response is 58-24kHz.

Enclosure Design

Curved MDF Cabinet: The TSx250C 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 TSx250C center-channel loudspeaker is available in either a black or cherry finish.

Flared Port: The TSx Series center-channel speaker features a critically-tuned, front-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 TSx250C 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 TSx250C 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 TSx250C 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.

Front and Center!

Written By TerryS, Portland, OR on Sunday, March 23, 2014
Crutchfield Customer Review (What's this?)
I was initially impressed with the size of this speaker which assured me it could easily handle anything thrown at it at any volume level--and it has, with aplomb! It is flanked by two equally sizeable 550t's that are bi-amped to improve high-frequency performance. As mentioned in my 550t and 220b reviews, I have a 5.0 system wired with Monster Cable XP sans a naughty subwoofer (which I may sneak in later:-) All speakers are set to "large" to maximize bass impact and general all-around "you are there" theatre realism--and it works! This speaker easily creates smooth vocals and upfront effects that seamlessly compliment the 550t's. The bass of ALL 5 speakers at once is bone-crushing--just like a real theatre; of course, I keep the volume at a comfortable level most of the time. The Tsx line requires minimal power to achieve all this--I keep the dial at -7db so my fillings don't pop out, ha! Now, if they only made a Tsx subwoofer (hint-hint).
Looks comfortable coddled between the 550t towers. Delivers whatever effects are thrown at it. Looks great.
I had to elevate my flat-panel a few inches to clear the top of the speaker for viewing, but I need to get a new shelf system anyway, and what better excuse!

Simply Amazing!

Written By Mark, Aurora, IL on Friday, June 07, 2013
Crutchfield Customer Review (What's this?)
For the last six years, I have had a theater in a box. Now, it wasn't just any theater in a box, it was a Yamaha. It had an actual receiver and actual speakers. Sure, it wasn't the best setup, but it was leaps and bounds above the more sexy home theater in a box setups that were a DVD/Blu-Ray player that hooked up to 5 horrible speakers and a sub.

Recently, I have decided to upgrade my system and I decided to start with the center channel. All I can say is WOW! This speaker blew my mind. I thought my system sounded pretty good before! This speaker brought my system to life.

I recently found out that I had my subwoofer set way to high. I believe I did that in order to compensate for the fact that my other speakers lacked presence. I turned the sub down and, although my system was more balanced, I felt as though my system lacked life. Then I added this speaker... This speaker gives new life to my system and has taken my system to a new level.

The only negative is that it now shows me how bad my other speakers are!
Great Sound! Looks Great!
I knew all of these going into it, but... Size (it's huge!) Price (but, I'd say it's worth it)

3 answers
  • Yes [ WILLIAM   Feb 02, 2014 ]
  • I don't know as I paired it with some Polk TSX550T floor standing speakers. My advice would be to try and match the wattage if possible. [ Thomas   Feb 02, 2014 ]
  • I do not know, I don't have the Rt4 bookshelf. I have the TSx550T towers and it matches nicely [ John   Feb 01, 2014 ]
