Hello,
Can someone tell me a little bit about Poly fill inside a sub enclosure. What does it do or not do to help the sound? Should I put it in my sealed sub box? Where do I get this stuff? Whats the science behind it?
thanks
Adam

As quoted from crutchfield: "The sound wave coming off the back of your subwoofer reacts with the air contained in the box. Poly-Fil stuffing slows down sound waves inside the box, making the subwoofer perform as if the box were bigger."
I have never used polyfill, i tend to build my box to maximum sub spec, a lot of people swear by it though. You can get it at most audio places, online Crutchfield or PartsExpress

cool, thanks man

Every sealed enclosure should be polyfilled. Always.

And buy it at Wally World. Cheap as hell, and comes in huge bags.

Where in walmart, i would be intrigued to see that

 

[Dr. Isotope]

In fabrics/crafts. The big bag is around $7.

Yes... also known as pillow stuffing and if I'm not mistaken.... you should fluff it up a bit.

thanks everyone,
I went to walmart and got a 1 lb bag of Poly-fill for $2.89. talk about cheap.

if u put it into a vented box, it will make for a much smoother and tighter bass....

But if you don't have a screen over the inside of the vent it will blow poly-fill all over your car

as stated above, if your going with a sealed enclosure then i would reccomend poly fill it, but sealed enclosures are for SQ=Sound Quality, if you want some thumpness, do a sql box= ported enclosure, tuned it around 30hz-34hz depending the sub your getting. I would pick ported over sealed any day

polyfil makes the sub think the box is bigger

It is all a taste preference, i prefer sealed because it just sounds so much cleaner and tighter than a ported box, and takes up less of my precious cargo room.

This is true I have never owned a ported box for that factor alone, I don't want thumpness I love accuracy, clean tight bass. Pollyfill is awesome I have used it ever since i have had subs and haven't regreted it since.

Sure you loose a little efficiency but hey its a small price to pay for clean tight sounding bass.
