Hi Serenechaos,
Please build me two of whatever you're makingOnly problem with "extending" the Azura to take a 2" throat is that it will be too darn long (!) We'll have to poke holes in the drywall.
Sorry for the OT!
~39" long to 1.4" throat...
and you saw the mid-bass horns w/ the 15" drivers are ~12" longer than that... (but they can be pushed up close to the back wall, so the mouth is in near the place a box/ob would be).
working on a driver (for the 160Hz horn) which is the first few inches of the flare, somewhat like the 650Hz MyEmia
Jeffrey will have them available, uh, sometime...
(everything takes longer than i guestimate)
