I have an infinity kappa 12.1 in a sealed box and I want to add polyfil to it. The manual says I could stuff the entire box with loosely packed polyfil. If I do that wont the polyfil interfere with the cone or voice coils? What do I do to get around this? Sorry if this is a repost but I searched and couldnt find.

Personally when I had polyfill stuffed into my sealed enclosure I felt that it sounded like poop. If you do want to put polyfill into your enclosure I would recommend putting a 1-2 inch layer of lining on the enclosure walls, attaching it either with staples or some 3M spray adhesive. If you use any type of adhesive be sure to let the box air out for 24 hours so the fumes won't damage your subs.

I'm stuffing it because my box is a little undersized and well the stuff is so cheap I thought I'd experiment a little. Thanks for the help guys
