I always found a bees hive to be the best material.

On a serous note - a question.

In relation to absorption material inside an enclosed box, as what point does the absorption material start affecting the volume of the enclosure.

I have a pair of Duntech Princess which I replaced the bass drivers.

(not my actual pair)

I was quite surprised to see the bass chamber was almost 2/3rds filled with some type of foam.

So lets say I wanted to make an enclosed IB bass box, With a huge amount of this fiberglass panels that have been discussed. How much do I account for the change in internal volume?

Absorption material won't affect the volume of the enclosure. It will reduce qtc, however the extension won't improve. Only the shape of the hump will clean up.
