    Polyfill in ported boxes?

    Should I put polyfill in my ported box with my Kicker 15L5? I heard that its only noticable in sealed boxes and that it fools the sub into thinking there is more air inside the box or something like that. Ive just taken my box apart in 100F+ so I'm dying here any help would be appreciated.

    it doesnt fool the sub into thinking its in a bigger box, this is a myth...people think that it makes the waves travel slower...but it doesnt..what it actually does, is it helps break up standing waves for better sq, but it decreases efficiency and elimnates higher end freq response, there fore making one think that the bass is more "boomy" so it all depends on what you want whether you put it in or not...and if you do put it in a ported box, make sure you put a grill over the port so it doesnt come flying out

    Polyfill in a ported box is a waste of time. You likely won't have any audible difference at all.
