Summary: I've listened to the super expensive speakers that didn't sound this good. Previously, we had a small paradigm which, granted, had big sound for a small speaker. What's great about this one is the bass for its size, mid and even high frequency response qualities. As the others mention, it's good size, though not the biggest one out there. It just sounds that good. It's also very accurate.
Summary: I have an entertainment cabinet under my TV that has a space that is exactly 18 inches wide. I needed a center speaker that would fit in here, and I found it surprisingly difficult to find one. Most are much wider than this. This speaker fit PERFECTLY at exactly 18 inches wide. It is a very attractive speaker, and the sound is excellent.
Summary: i've paired this speaker with Sony's SS-B1000 Bookshelf Speakers. Those are priced so well, that i was initially bummed to find i was going to need to pay over $100 for a decent center channel speaker. however, this speaker is such an improvement over the Sony Home Theater in a box speakers from which i was upgrading, it was well worth it.
Summary: The Polk Audio TSi CS10 is wonderful value for your money. Sound is fantastic, fit and finish is phenomenal. You do need to read the spec sheet, because this center channel is quite large. Pretty tall and deep.
Pros: Excellent sound quality, even better price
Cons: It is quite large. Be sure to read the spec sheet on dimensions.
Summary: Have been looking for a Center Speaker to fit my enclosure (19'"wide x 8" high.. I have very high end Klispch speakers but the Center is way to big for my new TV stand Center Enclosure after buying a 82" Mitsu HDTV .. I bought a smaller Klispch Center speaker but the sound is not up to the rest of my premier system (Yamaha "Aventage" model 2010, et al) Found this Polk product which just fits my enclosure.. So I read the reviews and as I have very high end stuff...
