Just going off my Tempest and DVC designs-- it looks like you may want to try a sealed cab with a qtc of 0.707. I've put my Tempest in three sealed boxes and a ported box but nothing sounds as good as the sealed 0.707qtc design. I listen to ALOT of music compared to HT. I've always been much more into stereo. I agree that the ported boxes sound great for HT and really dig deep but I always go back to sealed everytime. I can't explain why and don't know the technical jargon behind it, but "it just sounds better." IMO
