Surround speaker selection help

[benw46]

I have a large room and a currently 3.1 system. Power is a Sunfire Cinema Grand Signature (400 wpc x 5). Current speakers are Martin Logan Prodigy mains, Martin Logan Stage center channel, and one Paradigm Reference 15 sub. I am looking for two surround speakers and the contenders are Martin Logan FX2 and Sunfire Cinema Ribbon CRM-2BIP. I am leaning toward the Sunfire speakers because they fit the room best physically but I can't find any place nearby to audition them. Home Theater mag just had a superb review of the FX2s but they are a much larger and windows/doors make placement a problem. Any comments or advice greatly appreciated.....

Some of the on line stores will allow returns if you don't like them.

I also agree that its really important to choose the right surround sound speaker. A right surround sound speaker can create a whole new environment all around you. Surround sound doesn't just mean five speakers and a subwoofer anymore.
