1lb per cube; its enough. its only a 1.3 cube box. so 1 bag is perfect after displacements. :)

polyfil works wonders, not only it makes your box "bigger" but you get a warmer sound using. Thermodynamics ftw.

i'll tell you one thing birch is nice! i will never use mdf again, i saved soo much headaches by throwing down the extra cash for it.

What does polyfil have to do with thermodynamics

The polyfil turns the enclosure from "Adiabatic" to "Isothermal". Adiabatic means there is no heat transfer. Isothermal process happens when the polyfil is added.

When air passes through the fibers, they wiggle, and generate heat and makes the air less dense from warming up. Sound passes easier through a denser medium, the speaker interacts with the enclosure and and acts as if the enclosure was bigger.

It can make the speaker think the box is bigger as much as 40% in size.

Your box becomes more efficient now for daily use :)

so where you read that at? lol

would it be wise to use in a ported box.

*** sounds, by DevilDriver(i know he knows his audio :))

it can be used in ported enclosure, but i think there are too many variables to play the guessing game on tuning...if that makes sense

As you can see from 2nd clip my box is not completely sealed :( I just discovered

I clamped at 715 watts...i wish my dmm had a peak hold but it didnt so i took a video then reviewed the clip on the computer in slow motion lol

This is not my normal listening level at all, I just did it that loud for the hell of it. my normal level is 300 watts give or take
