Welcome, and that was not too long of a post. No post police here.

I have M80s in a closed HT that's 14 x 16, and I enjoy them. You could probably make do with smaller speakers in that size room, esp with a good sub, but I'll defer to others since I don't have any firsthand experience with bookshelves and smaller towers.

Actually, scratch that - I did hear that the M3 ($330) recently beat the Bowers & Wilkins 805 ($2500) in a head-to-head blinded comparison test ....
