I've seen this in several speakers like this. It's usually an attempt to deaden the can. KG's right... I'd choose polyfill instead.

Polyester batting or polyester fiberfill does the same acoustic treatment as fiberglass insulation. It will help retard some of the reflection from the interior of the pod, which (reflections) are completely coincidental given that the pod is round in shape. This creates a profound sonic signature at a specific bandwidth. But this type treatment doesn't do much to damp the actual material resonance of an aluminum or plastic pod. To damp the pod resonance, a few squares of sound damping mat (you don't have to cover the entire surface area) (like Dynamat, RoadKill, HushMat, etc.) or a solvent-based (not the latex variety) expansion foam will work VERY effectively.
Consider that once a speaker displacement is loaded into a small tower pod, there is not much space remaining...no more than you would have with a small tupperware bowl. So easy does it on the amount of whatever you choose to install in there.

Thanks all. I will pick up some polyfill.
Get the waterproof type of polyfill, just sayin':cool:
conformal-coated with CEA-2006 standards :cool:
