Question about polyfill?

[fishmunger 10+ year member]

polyfill is the same stuff as pillow filling they sell at craft stores right? Also, I have built 2 0.4 ft^3 boxes and would like to get them up to 0.6 ft^3 each. Roughly how much polyfill should i add, and does it matter where in the box it is, like just laying on the bottom? thanks

1. Yes, it's the stuff you stuff pillows with, available at Wally Worlds or craft stores.

2. The rule of thumb is around a pound per square foot...

3. No, it doesn't matter how it's put in the box, unless it's blocking the pole vent or something.

1 pound is probably a lot though huh? like i cant compact it or it wont work right?

You can get big 20 oz bags at Walmart for around $2 in their crafts department.

I don't know if cramming it in a box helps. I put about 10oz per sub in my last enclosure. You'll get deeper bass, but it's not as loud in some cases.

It's not recommended for ported or bandpass boxes.

Hope that helps. Can't go wrong trying a $2-$4 upgrade. If it doesn't work, make a pillow.
