Polyfill good or bad
#2
Polyfill fools the driver into thinking that the enclosure is bigger than it actually is. It does this by slowing down the sound wave inside the enclosure. I've been building speakers for a few years now and I don't hear any difference between stuffed and un-stuffed boxes. It's cheap to buy (you can get it at any fabric store) so go ahead and experiment with some.

Ok, in my experience the bass note seems to "hold together better" or distort less. It also seems to deepen the response because the air mass is moving slower.
With that being said, the general rule of thumb is 1-1.5 lbs of polyfill per cubic foot of air space inside the enclosure.

I do not feel that it sounds like I lost any volume, but just improved the overall sound of the sub. I am not saying its a night and day difference but I feel the subs hit "cleaner" with polyfill.

When I took apart my JL audio Powerwedge box it was filled with poly fill and then a flat piece of batting to protect the sub from the factory. I have used this box for over a year and had no problems, so I reused the polly fill and batting in my millhouse box and I am impressed with the way it sounds.
