I'm still search for a system. The water is quite muddy at this top tier. I'm looking at L'acoustics X12, Meyer UPJ-1P,Fulcrum FA22AC. I have eliminated Adamson and Nexo out of contention. d&b is also eliminated due to excessive cost. To my surprise, Fulcrum is the most expensive of them 3! Now we're talking about $5-6K per cabinet. L'acoustics are not expensive at all with aggressive discounts from dealers. I don't know if Fulcrum sounds better than the other 2 to justify the cost (over $1000 difference). I don't know. I'm stilling searching and debating myself. Another option, maybe a superior one, is Fulcrum DX1295 with Linea Research 44M10 amp. I heard that's even better than the FA22AC with the Powersoft module in the back. I'm not looking to save a few bucks, I'm just saying. I'm looking for the best sound I can afford and of course this is tough to do. Anybody that have heard X12 vs Fulcrum and can offer some perspectives let me know. Maybe it will come down to them 2, Meyer just doesn't have enough juice until you go UPQ-1P.
If you are looking for a lower cost box that's still in the top tier, the EV Xi-1122A with the FIR tuning sounds excellent.
It's an older workhorse but seems like it might be a good fit for you. The new JBL F12 may be similar but there are likely far less on the used market as it's only been around a couple years.
