Hi everyone. I bought a Harman Kardan AVR-525 a couple weeks ago. And yesterday after months of research I found the right speakers for my front stage. Energy Conniosuer c-5's for the front and the C-C1 For the center. Picked them because they sounded fantastic in a great demo room. And they are very effient. 94 db and 90db. Anyways I have a few options on what way to go for surrounds. First is 2 sets of C-S3 bipolar/dipolar switchable. Or 1 set of those on the side walls and some C-3 bookshelves in the rear channels. Or I could probably use the C-3's at all channels but I do like some ambient sound in the rear. Any help here would be great. Also between an Energy's 150 watt 10" sub and SVS's new box sub with the 325 watt bash amp. Would I be alot better of going with the SVS? Do you guys think it'll blend nicely with my speakers? Thanks alot if I get any replies.
