I've used polyfill a time or two in my day, but only in sealed enclosures. It's been said that polyfill will somewhat fool a sub into performing like it's in a bigger enclosure. Anytime I have serious confinement issues, I'll line the box with the stuff. I don't know for sure if it does a d*mn thing to be quite honest, but I've been guilty of doing it from time to time...

to my understanding polyfill reduces back pressure making the sub feel like it is in a larger enclosure.
