Product Details

Polk Audio CS20 TSi Series Cherry High Performance Center Channel Speaker, Model CS20CH

Let CS20 be the anchor to your multi-channel home theater system and is the perfect match for larger TSi Series speakers. CS20 allows a seamless transition between the fronts of your home theater system, providing a rock solid center image and crystal clear dialog. CS20 too big to put over your TV? No problem, just flip it over and put it underneath- its angled top will point the sound right at you.


  • Quality built cabinets
    Speaking of the cabinet (no, not the Presidential Cabinet), it's extensively braced from MDF with ¾" thick baffles. Cheaper speakers will use other material such as particle board which is flimsy, robbing you of good sound. With pewter accents, a piano black top plate and removable black grille, TSi speakers look awesome and take up less than one square foot. All models are available in a choice of black or cherry wood grain, so don't be ashamed to show off your stereo equipment.
  • Small size, big sound
    The OWM Series are designed to be used with TSi Series for rear surround speakers in your 5.1 or 7.1 system. They feature Capacitive Coupling Technology (CCT) which creates a gentle impedance dip within the range where conventional sealed-box loudspeakers are subject to severely reduced bass output. The result- you get 3dB more bass output over a fairly broad range. It's as if the loudspeaker's enclosure grew by 30 to 50% in volume.
  • Innovative speaker technology
    Like all Polk speakers, TSi is put through Klippel Optimization and Dynamic Balancing. So what does this mean? It means your speakers will sound awesome no matter what volume. Some speaker brands sound horrible at higher volumes. Not Polk. We make sure your speakers sound great, no matter what volume you play them at.
  • High efficiency design
    Compatible with practically all electronics, these are speakers that produce sound that's open, spacious and clear, even when driven by modestly-powered amplifiers and receivers. No matter if you just bought a new digital surround receiver, or are hooking up your new TSi Series speakers to vintage electronics, they will still sound great.
  • Narrow baffle geometry
    Bringing the best of both worlds- narrow baffle geometry is a design that creates a sleek looking speaker with slick sound. First the high quality cabinet is slender (less than one square foot) and tucks away easily in your room. The smaller-diameter speaker components are lighter in mass, translating to clearer sound.
  • Multiple small-diameter driver configuration
    In combination with narrow baffle geometry- this configuration provides a slender cabinet that sounds awesome. Why use smaller drivers instead of one huge woofer? Many reasons, first smaller drivers are capable of better detail than their larger counter parts. They also project sound over a wider area, so every seat in the house gets great sound. Second, we can minimize the width of the cabinet making it sleeker, giving you more room for a larger screen.
  • Silk dome tweeter and polycarbonate drivers
    The nuts and bolts behind TSi's clear and crisp sound quality. Forget speakers with harsh horns or hard metal dome tweeters- they'll grab your attention at first but after prolonged listening, your ears will get tired. TSi's soft silk dome tweeters and polycarbonate drivers sound smooth and natural. Your ears will relax and thank you.
  • High Quality Connectors and Internal Components
    We give you five way binding posts on all models. Other speakers make you settle for spring clips which can break. Tower models feature dual sets of terminals, giving you the option to bi-amp or bi-wire the speaker- a design only found on much more expensive speakers. Internal components include Mylar bypass capacitors- providing sparkling highs. At Polk, we don't cut corners; we use high quality components for the best sounding speakers.
  • Rich, smooth bass
    All TSi models feature Critically Tuned Flared Ports. Flared Ports minimize port noise ("chuffing") and ensure good low frequency extension with low distortion. With Flared Ports, TSi speakers reveal realistic, natural, full-bodied sound with rich bass.
  • Stabilizer feet keep your speakers from dancing
    Floorstanding TSi Tower Speaker models feature bold, fat stabilizer feet. These stylish feet ensure stability on carpet or hard floors so that all of the speaker's energy goes into making sound instead of rocking the speaker. Stabilizer feet help the TSi Series Floorstanding Tower Speakers deliver more precise bass response
