I wonder if Clayton has thought about a bookshelf version of these that might go with an open baffle sub? I thought I had the ok for M3s, but the wife recently axed the idea. M5s might work size wise (about 6 inches too tall), and I don't think they would work well on an entertainment unit that sits about 16 inches high. Any thoughts about this? or does the tendency for a entertainment unit to be close to a back wall make the whole idea a non-starter?
