I need some suggestions for a surround sound system with wireless rear speakers. There is not enough attic to get up into to be able to pull speaker wire. I was looking into the SONY HT-SS370 system. I would rather have an active subwoofer or get a system that didn't come with a subwoofer so I could get my own. I am not looking for a top of the line system. Just something that sounds good & has HDMI hook-ups. I would appreciate any suggestions. Thanks!
