Jason,
 
We are not building a speaker cabinet here.  Terry's box is very loud according
to his post.  Try building a simple box without a bottom and vary the distance
from the floor and you will note a dramatic difference in noise reduction.  My
theory is there is reflected sound back into the box that is out of phase and
cancels noise coming out of the box.  Try it, it's simple and effective.
