Pollyfil is a sound absorption, dampening fiber that will deepen bass, provide cleaner midrange, tone down any unwanted reverberation and improve the dynamic extension of any speaker system.
It also helps eliminate standing waves, which is something like an echo inside the box. This will give you tighter and more accurate bass. It also helps to give a flatter frequency response to the overall sound, which is good. Besides this, it also helps reduce the vibration of the box, which results in less distortion. There is a big difference to the bass when you have an insulated box.
Damping also increases subwoofer efficiency by dissipating some energy that affects the sub, particularly the voice coil. It is advisable to put damping material inside a box. Pillow polyfill and fiberglass insulation are common, though polyfill is a lot easier on your skin. Polyfill also "tricks" a sub into thinking it is in a bigger box. Most sealed and vented enclosures require 1/2 lb. of dampening material per cubic foot of enclosure. For best results it is recommended to loosely fill the material throughout the enclosure.
As long as the guidelines of 1/2 lb. for every cu.ft., all will be well.

I second Maggie's statement. Polyfill on vented? I thought that was a no no. But yes a bigger box in general, all things being equal, will deliver more bass. build one up. oh and in teh future consider upgrading the sub if you can get a great deal. Jl audio and RE audio are my fav's in the past two years

Somehow, yes. I dont know anything of how it does this. I think It pushed more air pressure out of the subs faster because space is taken up inside (?) Dont do it if your case is fiberglass or you can see it becuase it looks ugly. If this is the case (that it is transparent) I think you can buy specialized blocks to put in there! Good luck and if u want to chat cars my sn is Horseybabe1990 (yahoo)

No. The speaker is going to produce all the bass it's going to. The batting reduces the higher frequencies.
