Thanks Apachef1, my friend have this speakers and a Audio Research VT100 and a MF kw750, and also serious problems in the bass response of the speakers in his room. For that we wanted to try to biamp (VT100 in highs and kw750 in bass) and apply some digital parametric equalization only to the bass using a digital filter. I'm sure that this amping setup will outperform the VT100 alone as he have now (little booming also).
Instead of the answer of Wilson, do you try to biamp?
