Need advice on new speaker setup...

[etecnifibre]

I already have a Pioneer Elite receiver, VSX-23TXH, have some Paradigm ADP190s on the way for the rear. In the front, I want to go with a Monitor CC190 or 290, and some AMS LCR for the L/R, in wall. My question is, is it best for the bass drivers to be the same between center and your L/R speakers? Or will it matter that much? The AMS LCRs will be great because of my space requirements (in wall mounting dimensions).<p>
Also, about a sub, how much difference am I gonna see between something like the PDR-10 and an Ultracube?

Thanks for any input.

Did I post this in the wrong section or something?

It is best to match any sound-producing components between L-C-R. Rears are less important. Once sound becomes non-directions (80Hz), the need drops off.
