To make a long story short, I am ProAc-ed out. Build this speakers a few month ago and want to start some other projects.
Veneer: Birds Eye Maple with Burl Walnut bases.
X-over: Jac’s schematics. 14 gage Solen perfect lay air core inductors on the woofer, 14 gage Goertz copper foil on the tweeter.
Solen capacitors with 0.01 bypasses on the tweeter section.
Resistors are 12w mills.
Crossovers are housed in the bases so they could be inspected.
Cabinets are building with variable density laminations.
Anybody knows anybody?
Asking $1600
Hi-res pictures will be available in a couple of days but I do have most of the steps photographed, including internal bracing and so on.
Flared ports also.

I just did now, based on your suggestion. I am not in a great hurry to this, I’d rather wait for the right person who could enjoy this things. Anyhow, we all have friends and not all our friends have ability to build or design speakers (or desire). This speakers are already build and sound fantastic so my idea is “hey Joe, I know a guy, who knows a guy, who has proacs you could listen to” Anyways see what happens. I can always bring this home and use them as right and left in HT then we all switch to 9.1.

MDF comes in different densities. There are varieties of MDF that are called Fire-retardant, Ranger and also exterior grade. Sandwiching different density materials helps eliminate box resonance or I should probably say wall resonances. It's another step that brings us to a less boxy sound from the speaker.
Veneer is pressed on MDF panels before the speaker is assembled and actually before the panels are cut to size. Vacuum pressing is my game.
Gluing is done with Unibond 800 or other formaldehyde urea resign.
I only use catalyzed adhesives, especially with difficult veneers and Birds Eye Maple likes to move after gluing, plus it doesn't like alifatic resign (yellow) glues and quite often chemically reacts with it (turns pink in a few month).
