I know I know, it is not the best of subs out there but now the worst either. I have a subsonic 6 that seems to bottom out easily. I had the driver out about a couple of years ago. Anyway, when I was in there, I noticed stuffing around the lower part of the sub. It is dual ported around the top part of the sub.... Also, here are some specifications. Naturally, I have it calibrated to the rest of my system. Is there anything I can do to help it out?
