Are you talking in reference to acoustic stuffing used in speaker enclosures?

It it my understanding that it means 100% of the internal volume of the enclosure filled with acoustic stuffing.

Here is an interesting article on the subject.

The problem is that the term isn't standardized. I'd consider maximum fill to be 1/3 the volume of the box. You shouldn't be leaving no gap for the voice coil to breath in.

My problem is that a percentage does not suggest density. Do I want the fill to be fluffy? Do I want it to be stretched as fine as possible? I could jam four shredded pillows into my box or one.

I pack in 2.5 density rockwool for fill and then cover it with a sheet. My cross braces are usually a third into the box so I just fill it up to that point. Don't compress it too much though. You are filling the sub not compacting the sub.

Yet another good point :T :rofl:

I'll keep this in mind if I ever need to stuff an enclosure.

In my experience, "100% stuffed" means using 16 ounces of non-compacted fill material per 1 cuft of enclosure volume.

Agreed. One pound polyfill per cu.ft. = 100% fill. If the sub has a vent pole then it will need a couple of inches of clearance between the back of the sub and the polyfill.
