Tapered Wave Tube with Damp-Duct (TWTD) + Pluvia7HD

Thanks, I appreciate the comment. I think you are right, and will definitely look into chamfering them. In all honesty, it's a detail I missed but it makes sense to do that if only to rule out the possibility of interference.

Another is adding damping to the inside of the frame's 'legs'.

Historically, cheesecloth was used to cover the components.

Yes after using Kapok for pillows I would never do it in the house. Dust everywhere. Practically need a mask because it is very irritating. Acousti Stuff or fiberglass might be easier and cheaper Kapok is pretty expensive. Going down that rabbit hole too.

Interesting, I don't think I have seen that before.

Yes damping pads can only help with lots of problems won't effect volume. Strange how adding fill effectively increases the perceived volume. Something to do with slowing speed of sound or something, not sure. Play around with the fill amount with your new mic and you should get darn good sound. As far as the Kapok dust just put cloth around driver basket. Seen it in commercial design when rock wool was used. Looks like stretchy panty hose material. The voil coil will not clog up with all that dust when cranking that bad boy up. Imagine it sounds real good at high spl.
