Thanks for the kudos on my set-up. Yes, I was very concerned about concealing the speakers because of performance factors. One good thing is that in every area where the speakers are located, it is open-air to the back, so there is roughly 3ft of clearance from the back of the M60's to the wall. I did some "testing" with doors open and doors closed. I could not detect a significant decline in audio inteligibility.
My next task is getitng my QS8's wall mounted. I feel that my front stage is perfect, but my surround placement doesn't utilize the QS8's abilities to bring out the depth of a HT experience.
I have to agree with all the comments about showing off the speakers. I would rather have them in the open than concealed but what I want and what is reality are 2 different things. Cool thing is that my wife is down for another subwoofer...
Thanks all for the comments,
Steve
