The whole thing is supposed to be vertical, as shown in the link below, give or take for seat height of course. This link also displays the active analog crossover. The above photos are from the sale ad prior to me getting them.

Drivers per system:
2x TMH 12" woofers
2x Dynaudio 15w75
1x Electro Voice N/DYM1 (neo version DH1A)
Can assume we know specs on the EV and Dynaudio stuff. Would need to measure the custom TMH woofers, which is tipping me over the edge on the purchase of that OmniMic V2 / DATS V2 package from Dayton.
Woofers are wired in series and are 4Ω each, presenting an 8Ω load. The mids wired in parallel and are 8Ω each, presenting a 4Ω load. The compression drivers have 8Ω diaphrams.
Trying to secure a Dreadnaught with 5 high power channels to run the top boxes. Can pull out an old Macro Tech 1200 for the woofers. Being a 2ch single amp guy, this is a bit of a learning process but one I think might pay off in the end.
