Subwoofer Equalization?

I have a STF-3 subwoofer and am very happy with it. It has a nice home in the corner of my room and there is really no other place to put it. When I tested the acoustics there is 6db peak around 60 Hz and 6db dip around 40 Hz. I was wondering if you could run the sub out from my receiver into an equalizer of some kind and then run the out from the equalizer into the STF-3 to level off the curve. I imagine I could fix things by moving the subwoofer but that really isn't a practical option in my room. Any ideas?

Behringer makes a parametric eq that will do the job fairly cheaply.

Keep in mind you can't EQ out the dip with EQ gain at that frequency; you'll just waste power. You can cut the peak and overall level to match the dip though (crank the gain higher on the sub itself to get the overall level higher).

See my post http://hsuresearch.com/forum/showthread.php?t=1008

I also had both humps and holes. Tried raising the hole with EQ and got terrible transient response. Then raised the sub's gain to flatten the hole and knocked the humps down.
