Hi there,

I've been researching forums recently to try and build out a home theatre system. I've decided I would like to go with the following:

Front: RTI A3
Center: CSI A6
Rear: RTI A1

The room is a fairly closed off 14'x14' so I wasn't sure if I should just run 4 A1's or not and by the looks of some posts I've read, I would be better off getting the A3's for the front. The next step is a receiver and I'm having trouble understanding what I need to power these. I was looking at the Denon AVR-S720W as it will give me the opportunity to upgrade to 7.1 later if I want. Is this receiver something that will give me the correct power to drive the speakers (and a subwoofer when I decide on that)? If so, would anyone recommend the receiver? If not, any recommendations on what I should be looking at?

Any help or comments on the matter would be greatly appreciated.

Thanks in advance,
Q
