I have a sealed enclosure I got from a buddy that I'm going to use for my 12"s. The thing is, each chamber has about 1.2cubes when the subs recommended sealed volume is 1cube. Will this be a big deal? The enclosure also has all sides lined with 1" of poly fill. The manufacturer recommends this in the manual, but I'm thinking since the box is a little large to begin with I might want to take it out? But I've also read that the poly fill makes a more natural bass sound, and that seems kind of appealing to me. Let me know your thoughts on this, thanks!

I doubt you will notice a difference.

If it is too big it begins to act like an IB subwoofer.

naw for sealed box, little deviation will have little to no affect on sound.

After your sub displacement, that 1.2 will be **** near 1.0ft^3. Leave the polyfill, it wont hurt it. Typically oversized sealed boxes extend the lower end and increase the effiecency (sp?) so you dont have to use as much power...

Yes, but as said before, if you make it TOO large, then the speaker will behave like it's in an infinite baffle install.
