I was just wondering what exactly does dampening a sub enclosure do. I know its supposed to make it louder and deepen the bass but how effective is it. Very or just a small difference??

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 internal enclosure space. For best results it is recommended to loosely fill the material throughout the enclosure.

"Dampening" an enclosure by stuffing it with poly fill basically just makes the sub react as though it's in a slightly larger box. This can improve the deep bass extension. It won't make a very big difference. It's also only useful in a sealed box; stuffing a ported box won't do anything for you.

there is a large difference,put some insulation in the enclosure and you'll be good to go.with a sound dampner the bass is slowed down and there for given more time to grow,which means better bass.And it will help you subs live longer
