Unlike the electronics, your speakers won't go out of date, so bring out the most in your entertainment experience with Polk TSi Series. A great match to the TSi Series, the Polk Audio CS10 center channel speaker--the most important speaker in surround sound--is smaller than its sibling CS20, but still sounds just as good. And it has an angled top allowing you to invert the speaker and place it below your TV--directing sound towards the listening area. The TSi Series and the CS10 were designed to be highly efficient, so they can be driven easily by unpretentious receivers, and they're voice-matched for lifelike surround sound environments. This speaker in black measures 6-12 by 20 x 9-34 inches (HxWxD). The Polk Audio CS10 center channel speaker in black (see larger image).
