I kind of like the power cord/cable suggestion as they may be part of the problem, as well as the room. Many constantly upgrade cables to get the mids and highs (as well as the bass) just right. Why not try this approach in particular for low end problems as well? I have not listened to an analog equalizer in a system since the mid 70's, but if they have not been greatly improved they would tend to compress the sound much more than a typical cable, IMO. My experience with them aslo was that their sound character (compression) was less noticeable on 3 and 4 way speaker systems and more so on two way systems. I don't know why this was, but it seemed to be the rule of thumb. As far as equalizers go perhaps a 30hz filter would give better results by clearing up available power reserves to handle/control what is left. Now what are some "great" cables that have "no bass"? LOL.
