Will this work as polyester fill for a sub?

Will this be ok to put inside a subwoofer? If not what is recommended that is available from home hardware or lowes?

I see no reason not to... better cellulose than fiberglass! Only issue, common to both, is placement control - a little netting or thin cloth to keep it away from the driver lest the fibers find their way into the coil gap. That's one reason folks will use entire pillows.

Have fun,
Frank

I wouldnt, polyfill or regular fiberglass will at least retain its shape, this will settle to a pile on the bottom.

can someone explain how to fill a sub with pillows? Do I remove the stuffing and put it in? How do I get it to stay in and not just move around?

There are two ways you can add fiberfill. The bunches of the stuff like you find in pillows, you simply pack in loosely. 1LB of fiberfill per cubic foot of space in the woofer is usually the rule of thumb for filling it. Or you can add it a 1/2LB at a time until you like the results you're hearing. Either way, between the "rigidity" of the fibers (for lack of a better term) and the amount you'll end up adding, it's not going to really move around or settle to the bottom. The alternative is lining the box with fiberfill batting, which is more consistent like a fabric, though it's the exact same material, just "woven" more tightly. This will keep it away from the driver and look a little neater - not that you're going to be seeing it again, but some people are anal retentive about these things. biggrin.gif If you decide to go with the loose stuff, using a bit of netting or fabric to keep it away from the driver, just in case, is a good idea as well, as previously mentioned. And definitely make sure it's fire re.tardant.

make sure the pillow stuffing is fire retardant or just the mesh? Do they even make pillows that aren't flammable? :P

I was speaking to having retardant fiberfill, but anything you add to the interior of the cab should be fire retardant if possible, for no reason other than an ounce of prevention is worth a pound of cure.

As far as flammable pillows, it never hurts to double check; you never know what's found its way to a shelf biggrin.gif Also, plenty of craft stores and online retailers sell fiberfill on its own for myriad uses, so depending on your location and how much you decide you need, you may find a better price point buying the material, instead of stocking up on pillows. On the other hand, you might find a fantastic deal on pillows - just food for thought!
