The thermal effect that makes the woofer think it's in a larger enclosure is mis-understood and mis-reported all over the net, it's a subtle, barely audiable change that's completely swamped by the damping properties of fill.The change that ManJo heard was because he lost almost 3db off the peak of his subs response, the fill damps the motion of the sub like the shocks on a cars suspension damps the motion of the springs.Adding more will simply increase the effect (up to a point) Fill is a SQ tweek that tends to smooth out a subs response at the cost of peak SPL, it will never, ever, ever make a box louder.</blockquote>
