I had four QS8s. They were 12 feet away for sides and rears. They are puny. I traded all four of them in for two QS10s for sides. I dont even miss the rears. They are soooo much better. I was missing so much. My Onk found them at 40 Hz (like my M5s and 160) and that's where I've kept them. I'd really like to trade them in for QS14s though. M3s are also a good choice but if you choose to mount them close to a wall, you may need to plug their sphincters. On wall would be a good choice also.

Yeah, I love the M5s. I love them so much that they'll have big brother M100s to look out for them in about two weeks time. smile
