I can't imagine that working. Probably the best bass improvement (assuming you have a sub) is from this procedure: put the sub in your listening position, play LF calibration tones (available on many receivers, and various calibration CDs), crawl around the room with a $35 Radio Shack sound meter. When you find the highest bass response on the meter, put the sub in that position.

It's not fancy but it will usually give a major improvement, assuming you haven't already done it, have a sub, and your room layout allows the reposition.
