I beg to differ. Bandpass boxes boom a lot, but the sound quality is lost because of the amplification of the tuned frequencies. Sealed box have a higher sound quality but don't rattle your teeth as much. Hopefully he will seal it. Free air subs are the worst setup IMO.

I like the idea and I really want to see this. He might be limited to smaller 8" or less subs and will need to use grills. Unless he wants someone to accidentally kick the subs in.
