i have modeled every speaker in my database and found that implementing a high pass filter before the amp (at 40, 60, 80 and 100hz.) causes a huge 6db hump at the crossover point.


Huh? When I went through the process of eq'ing my sub, I plotted my sub alone, my mains alone, and the sub + mains, from 20 Hz to 98 Hz (Autosound 2000 test CD) through the 60 Hz crossover point. I never saw a 6 dB rise. In fact, most crossovers I'm familiar with, set the high pass filter for the mains at -3 dB and the low pass filter for the sub at - 3dB at the crossover freq so that you get *flat* freq response through the crossover point...
