@avsjerry I’ve an older dbx 2way, a more current Behringer 2496 w/sub out, and an ESS Eclipse 2241AM which seems to be a rare bird item....
Electronics Crossovers:
Why not test and try the 2241AM. I have one of those too :), but don’t use it right now. If I had two of the same amps I’d try it again. Maybe some bits to replace inside due to age. Might be a future retirement project redo. Try that if you can, and then compare to your Behringer, w/sub out. That might sound better if you have really good subs. That sounds like a good idea too. Go for it!

Rear-V:
Re: AMT Di-pole rear "V" design is something I tracked to with another group of engineers when ESS Labs got bought out and was shipped overseas to Europe for a number of years. See ESS 450 below. Saw this in euro and us photos too.
ESS generations of the Co:
Later they went over brought it all back on containers/boats. I’ve got photos of Transar ATDs in rows that came back to LA stored, argh.
Future:
At one point I had this dream of waiting til they are done and buying ESS, what was left of it, and bringing it right back to Sacramento CA as my last bucket list retirement project. Good to have dreams. No need, I can build my own now :) I had a local audio chain ask me to manufacture/build them and they would sell them in their hi-fi room. I guess I wanted to keep my designs private, just for me LOL.

Another photo for inspiration. :) ESS 450 not regularly seen here in the USA.
Hey they even had your vision for 7" drivers with AMT, here it is.
