* Polk Audio CS1 with BOSE supporting cast ...
I was using a Bose double cube for my center channel. It was weak, and insufficient. I decided to go with the PA CS1, wow what a difference. Great sound at a lower volume. Vocals are clear and defined. I tested the unit listening to that "movie previews guy" voice. EXACTLY like it is in the theater. AMAZING. Even regular TV voices/narration sound waaay better, (I watch alot of NGEO, TruTV, Discovery etc.) programs that have lots of narration.
One note, it's big. But if your TV is 50in or larger, it looks decent. I think if it was with a smaller TV 42 in or smaller it would look overwhelming. If you have a large rear projection TV >60in, like I do, it looks great sitting on top of it, like a "beefed" up version of your TV. I like this look personally. Maybe it's a guy thing. I wouldn't get this if you don't like big speakers, and want to be discrete about it. But I'm personally convinced you will NOT get the same sound out of a BOSE center channel than you would with this. BOSE double cubes are great for surround, but that center channel was weak.

* Actual Dimensions - Pretty Big ...
Unfortunately, Amazon doesn't understand that "17 pounds" isn't enough for the Dimensions field. Here are the actual dimensions.
18"w x 7"h x 9-5/8"d
To give you a sense of scale, that is about 1 inch wider than most home stereo components (like your amp, receiver, or DVD player), so it'll stack, but there will be a little overhang. Just think of it as love handles for your center channel.
The price and sound quality more than make up for the largish size, as long as you've got the room. Be warned, this beast isn't wall mountable.

* a bit larger than expeected, but very good overall ...
make sure you check out the dimensions before you order, to know if it fits on your area. i have sitting on my tv stand and it hangs over the edge a little bit in front of the TV. other than that, it produces very good quality sound.

* Worth every dollar ...
I purchaced this speaker along with four Polk Monitor 30 satalites, a Pioneer VSX-1017TXV-K receiver, and a Velodyne VX-10 sub about two months ago. I did tons of research and read hundreds of reviews for about a month before I pulled the trigger. The center channel sound is a perfect match (to no surprise) with the other Polk Monitor speakers. The sound is warm and crisp, but not too bright. Voices sound natural and well defined. When watching a movie, it really feels like i'm in a theater. My budget was 900 dollars and I can't believe what I was able to get. Through my research, I don't think you can do much(if any) better for 900 dollars.
