Hi guys,
Thanks for all the input. I looked through all the options I could find and was very pleased to see there were more viable choices than I thought there might be. Each of them seemed to be either very pricey or more compromised than I had hoped, so I sat back down with the thinking cap.
The thing I forgot to mention in my original post is that I live in Bermuda and, given the threat of hurricanes (much more of a threat than a reality, but they do come through once every decade or so), our houses are built of cement block rather than 2x4's and hardboard. That opens the possibility of setting some speakers that are up to 8" deep into the wall. So, I called Jim Salk and asked him if building some custom "Song" series speakers was viable for the application, and fortunately he said yes. Placed the order last week and can't wait!!!
Thanks again for the pointers though - they all really helped me make a decision that I feel very comfortable with.
Cheers
Will
