Thanks for the replies on this. I went to the fabric dept at the local
walmart & got 4 22" x 22" x 2" polyester fiber cushion squares,
basically the fiber but pressed into a square. 8 bucks each (I was
surprised how much this stuff cost at a fabric only store). It's nice &
firm so it can be shaped easily & is rigid enough to hold in place w/o
glue. Already did one box, I think it will be great for this
application & not too expensive.

Some actually like loose wool (from sheep yet), but to me that's going too
far. Most designs I have seen just involve layering the material inside
without packing it tightly. There were several quite good books produced in
England on ways to make speaker boxes that are high quality.
