Help on finding an in wall center speaker


I'm putting together a theater and am using paradigms all the way around. I'm confused on what to use for an in wall center speaker. Paradigm does not have an in wall center speaker. B&W does. Any recommendations or thoughts? Thanks again in advance for your help.

B&W sells a ton of their in-wall speakers: I've heard them and they sound good to me. You might also check out Polk'n new amplified in-walls as well as RBH's line (pricier but also much more dynamic w/higher power handling ability).
Thanks for the input Bojack. I'll check into the Polk and RBH. It's a large room and so the power handling is important.
Is it a bad thing to use the same speakers for Front/center/rear? I bought 5 of the B&W cwm650 in-walls. Should I have bought their center?
