How much fiberfill?

Steve@3dai · 11-19-2002, 04:12 PM

Just got my MM124 today, and installed it into a Subzero .88ft3 hatch box. Right now it sounds awesome, but I was wondering if I should put some fiberfill in there? If so, how much? Thanks.

well... addin a little polyfill is gonna make hte sub think the box is bigger so you'll get like a little deeper bass response - but keep in mind that this will probably reduce your ability to drive the sub "hard" -- if you're driving it slightly beyond its means or right to its limit now, adding a pound of polyfill will decrease you're ability to do so...

half of a pound is usually "good" for a 12 inch 0.88 box.

Steve,

Agreed on the .5 /lb per cu ft theory, but at the minimum, throw a little in anyway, if for no other reason than to help nullify the 'back wave' from the woof.

Cheers,
Rooster

Ps, I know where you live, I WANT that deck in the g-ride.
