What the polyfill does is make your box 'feel' bigger to the sub. I've heard people say it will lengthen the life a sub has and stuff like that. I used it cuz it came with my box. I've seen pretty knowledgeable people go without it though. I guess it's a matter of preference.

if you just stuff 1" border line ( as in most sub manual says ), it wont do crap. but in my box, i have 4 bags jammed in, and it drasitcally changed the sound of my sub.... made it sound a bit more similar as a bigger box, but it isn't the same...

Polyfill in a ported box is a bad idea. Your tuning should be off considerably. :confused:
not a bad idea at all. many high-end home audio systems use polyfill in their towers. with polyfill, you can get a smoother bass response and probably lower-extention bass.

may not work for all, but worked for me any many other people. depends on application though.

some one explained it to me once that it makes the air tighter or some shit like that I personally dont know how it works but i can say that it has worked in my freinds set ups and we have noticed a difference

Well, I went and got some today. All I can say is...I wish I wouldve gotten some sooner. I did make a big difference in the quality of sound. Its tighter and deeper. Mabey it dosent work for certaint setups but then again, most setups are very different. It works well and Im pleased with it. Now I have to get rid of that annoying rattle :lol2:

We usually don;t do it by the bag. I just place about a 1''-2'' layer inside the three sides of the box. People have asked me if they should staple it to the inside of the box. You dont have to, it doesn't really matter as long as the bare wood isn't showing. You don't want to pile that shit all the way up to the woofer basket either.

mine is filled inside....

general rule...1 lbs per cubic feet (or close to that). 1lb is a lot of polyfill to stuff in a 1 cubic box. you'll have to stuff it lightly and spread it around. don't want any clumps on one side and nothing on the other.

i'll try to take pics of my box someday. probably later in the afternoon. as far as the polyfill touching the basket..well..it is..lol.

no harm is done. since the polyfill is in one big pieces spread all around, there is no chance that a small clump can get into the vented pole piece.

actually..i'll try to take pictures now..lol
