I have an eye on the Berhinger SHARK processor. Small and cheap but the cut is only adjustable from 20 to 150hz, and it seems the slope is very steep and non adjustable. looks like 24db per octave or more.

any other idea

currently using the Feedback Destroyer Pro for equalization.

Sure - use an active analog filter.

Filter design with opamps is fairly simple. As far as specifics, the guys on the bass list concluded that a -12dB/octave slope would be sufficient and suggested a -3dB point perhaps 10% below F3 on my subwoofer.
