I was just wondering can any sub use a sealed or ported or does it have to have certian parameters in order to decide the box. I was reading on a website and it said subs with a QTS of .2 to .4 is good to used ported if so how come boston acoustics 8.5lf only has specs for a sealed box.

'Cause Boston recommends sealed enclosures for their subs. I owned a 12.5LF and hated it. Terribly inefficient and didn't do anything particularly well (apart from blowing up on several occasions).
