...PLUG THE HOLE! I ain't kiddin'! Let me tell my story... I have a Bose AM3 system that I hate very much... So, I was walking around the basement today when I came across some open-cell sponge foam. I decided to tape this substance to the front of the Bose Acoustimass module and was surprised to find how it improved the sound. It made the bass softer and less "boomy" and it even made the whole system sound a little better than it used to. Here's some pics of the Acoustimass Module...
