View Full Version : how much polyfil is enough?

I want to use polyfil in a 1.6 cubic foot box after sub displacement to make the sub act as if it was in a 2 cubic foot box. What are the guidelines behind polyfil usage? Is what I want to do even possible?

Not gonna happen. it might cover for .1 to .2 cubic feet max but not .4. Your going to need a lot more and you'll be introducing a lot of heat if you over stuff it.
