stupid question, does it matter what i use to raise the sub, and does distance from the floor make a difference? since i moved i have 2 amplifier stands (commonly known as end tables) not in use, that are 14" high, one of which has a solid 2" wood top, the other has a center cutout which i removed the metal bottom for additional cooling, as the amplifier was wide enough to sit over the center cutout. the sub is not wide enough and would actually sit down in the center cutout on the metal almost 2 inches down. all of which sounds like a bad idea. the solid wood top end table is 2 inches thick, 21 x 21 x 14, heavy and sturdy as hell, so not really worried about vibrations. as the stand is larger than the footprint of the sub, how far back should the front of the sub sit from the edge of the table, flush, a few inches or does it make a difference?
