I've been reading around and the advice for stuffing tends to be 1lb per cu/ft of air. My question relates to making the box appear larger when it's outside the manufacturers specifications.
Subwoofer: Audison APS8 D4
Recommended box: 0.3cu/ft (8.5l)
Recommended Qtc: 0.86
My box is 8.75l, a little larger than the maximum recommended size according to the manual. I read that if I stuff the box, it will make it appear larger and thus lower Qtc, which might help with transients and flatten the response curve. With stuffing, I could make the box appear 30% larger, but the Qtc will still remain around 0.8. This seems desirable, yes?
What problems might I have if I make the subwoofer box appear larger than recommended?
