I've been putting No Rez into old speakers like the Advent 3002, but I'm wondering if I should modify the amount of fiberglass stuffing after adding the No Rez.

I can't really tell if putting all the stuffing back in is causing a change in bass response because these speakers are usually non-functional when I receive them. I refurbish them and give them away to keep them out of the dumpster.

Should I leave out enough stuffing to equal the volume of the No Rez, or  am I obsessing about nothing?

The damping layer take up air space. The foam layer adds air space. It is about a wash. You can add back the original damping material for fine tuning.

Are you sure about that Danny?

Yes, it slows down the air flow in the box and makes the woofer act as if it is in a larger air space.

It acts like polyfill. I've used it more than once. Nice product. Sounds like you should check it out

Very interesting and good to know. Thanks.
