How to use Acousta-Stuff polyfill material. Please help. (1 Viewer)

[Jeffrey_S]

I'm putting my Tempest sub together today and I was wondering if I need to glue this polyfill material to the cabinet walls or can I just let it lay freely in the sub? The sub is down firing and has a built in plate amp.

Thanks for the help!

It's really a choice, between just lining the walls or fluffing it up and filling up the volume evenly.

For my car subs, I fluffled it and sorta packed it in. I think the object of the polyfill is to slow the air movement inside the box and not just sound dampen the walls.

Adire's program adjusts a % of polyfill, so I'm beginning to think that you're supposed to fluff stuff it.

Chris,

Thanks for the input. I just stuffed it without spray adhesive. I couldn't wait any longer to get this baby makin sound. It's been breaking in for about 3 hours now. It sounds better with each passing hour. I'll start a new thread with pics and my impressions tomorrow after an evening of playing music and some of my reference DVD's.

It's supposed to be fluffed. Fill at a rate of 0.5-1.5 lbs/cu ft.
