Obtaining a good punch!!

Dude, he's got a nice energy system. Don't become the guy that has one answer for every question (get an eD A2-300).

I would guess that you need to experiment with placement and calibration. If you want more punch from your sub, why not up the crossover point a bit? That'll give more of the load to your sub. Maybe try an 80hz crossover point? Not much difference, I know.

Try corner placement, changing the volume, running calibration again, changing the phase. That sub has a 21hz extension.
