I have a week off over Thanksgiving and I have decided to try my hand at constructing a combination bass stand and bass trap, to be used under my Outlaw LFM-1. I am making it out of 2x10's with 1 1/2" MDF top and bottom. I will be drilling a bunch of 2" holes in the sides then wrapping it with black cloth.

My question is this: what would be the most effective bass absorption material to stuff the box with? There's a lot of products out there and I don't have a clue as to which would be the best for this purpose.

I would appreciate any and all suggestions.
