MaX Posted April 21, 2008 Report Posted April 21, 2008 they use the cotton or polyfill in the sealed boxes cuz it makes the sub think that its in a bigger box, giving somewhat of an increase in the output(spl) Quote <div align='center'>03 RAV4 18" DC Level 4 XL Knukonceptz 1/0 gauge AudioQue 2200D 6.25 cubic foot box tuned to 32 hz DB Linc 200 Amp H/O ALT 1/0 BIG III</div>

sully Posted April 21, 2008 Report Posted April 21, 2008 I used to loosely pack it. Not too dense or it defeats the purpose. Can't even remember the last sealed box I built, almost everything I build is ported or bandpass... If built properly I don't see the need for any.
