So these drivers have been sitting around for over a year(!), but as you can just sorta make out from the first pic below, there's now a stack of cut 3/4" Baltic birch panels. Which I would call a bona fide build start. Hence the post. Assuming anyone else likes build threads as much as I do.
The box sim is outlined here. It's gonna be a 26" cube of 1.5" Baltic birch all around, which is nominally 200l, but driver and passives might make it more like 180l. Hopefully a bit more, not less. PR mass of 2500g is John at AE's suggested max, making tuning 15Hz or so. Something of a size/tuning/SPL compromise, several dB down from Ilkka's tested results, probably, but I'll live...
This is one of a future pair, but no room for the other twin yet, so that set of driver/PRs will just have to chill even longer. Power will be via Crown CE4000 fronted by Behringer DEQ and DCX.
Present sub is a 15" Tumult MkI in 100l sealed powered by a Keiga KGND52100 fronted by Behringer DEQ. Hoping this PR'd box will outwoof it some, especially in the lower end.

More pix as build progresses.
