Actually, I lift my sub about 2", thinking somehow that doing so will help the sound. One one hand, his is probably irrational: the sub fired out, not down; on the other, it seems reasonable, since it has been placed inside an schrank, where the vibrations already give the doors a good, occasional rattling. So far I like the sound. I haven't done an A-B comparison: most times the volume is cranked low enough to be scarcely discernible. But, I am not you, so who knows? Why not give it a shot?
