Some of you may remember that Gex sent me his HWK8 shell a few months back.  I have it set up right now with 2 8" generic woofers and 1 4"x12" round port on top and two 3"x1.5" ports on the bottom.  Drivers are mounted mag to mag in the center chamber and wired push pull.  Without proper porting the two chambers are very similarly tuned because of thier similar size, i plan on expeerimenting with some stuffing in the low chamber to get deeper extension.  The woofers that are in there are weak in the lows tho, and i need some suggestions from y'all for good 8" 'subwoofer' candidates.  Preferably high power drivers as this box is solid, and i wanna pound the crap out of it.  Anyone have suggestions?

the apexJR 8" is very reputable.  www.apexjr.com
