[QUOTE="Mark Wilkinson, post: 203882, member: 8989"] Very interesting construction Paul. Thx for sharing what you're doing. Looks great !! Looking forward to hearing how the mid section tests out with all the curved pieces . Also interested in your sound dampening. I've been trying trying some of that too. Nothing to say one way or another yet. FWIW, I had to go to heavier handles, and really screw down my interchangeable baffles to nix resonances.The box can move a surprising amount of air for only going down to 100Hz. @Peter, Don, Paul, et al, Hope to measure harmonic distortion at various SPL's this week. Will post results....maybe folks with more experience can see ways to dampen whatever harmonics show up at high levels. [/QUOTE]
