I am considering placing my subwoofer at the bottom of an L-shaped rack of equipment. The Bello AT-484 to be exact. There will be a 19x14" glass shelf over it, 3 more directly over that shelf and a fairly thin L-shaped rack support on either side. To me it does not seem like any of this is big enough to interfere with the sub sound. But what do I know ? I read subs are fussy about position. Anyone tried this or have any comments ?
