View Full Version : millionth polyfil ques.

I got a SS T-5 from pipo in the classified sec.

I'm gonna use it in a sealed box. The specs call for 20-50% semi-dense fill.

What is your interpretation of "20-50% semi-dense"?

I know the Lb to cu.ft. rule.

Thanks for your help.

The box building is in the capable hands of tacosys.

Just stuff some in until it's packed, but you can compress it into ~2-3" deep against one of the walls. That's my rule of thumb. It ends up being filled up, but loose enough to not choke the sub.

And no, 1 lb of polyfill to a 1 cubic foot box is almost always too much. If you're worried, just line the walls with 2" fiberglass. Seems to work better anyway.
