Maybe you should go back to the dealer and have a look and listen to the B&W SCM-1's, which are basically a wall mountable N805 and for that matter could go on a shelf. I believe once mounted they are only 7 inches or so deep..you also might want to check the B&W site for exact specs. As far as your power concerns go what were you going to use... separates, reciever etc. As I had mentioned in my earlier thread to you I had just heard the N802's at a dealer...who had just finished a demo for someone else using a reciever "Rotel 1065" to power them.. the reciever played them louder than I would ever want and is rated I believe at 100 "but clean" wpc. I'm sure others here on Audiogon will sound in soon and give you more useful and technical ideas... I only know what my ears heard, trust yours!
