I just purchased the CMT-340SE L,R,C speakers. I was wanting to know which surrounds to get. I'm using the VideoSecu http://www.videosecu.com/side-clampi...peakers-ms56b/
mounts for my 4 rear surrounds now. The only issue I might have with the 170's is they recommend 3" of space behind them for the ports. Since my speakers are wall mounted they would stick out from the wall about 13". The ceilings in my basement movie room are only 6'8" so the speakers already are at a height where you can run into them if you're not careful. The back wall ones aren't as bad but the side wall mounted ones will get you if you're not paying attention. Is the sound quality that much of a difference between the 170's and 200's when used as surrounds? I have a 12" 500w sub and I'm using a Sherwood/Newcastle R972 receiver. My room is 12Wx22Lx6'8"H and is completely walled in except for a doorway on one wall.
