Lol, as Oddball, feel obliged to throw in a curve ball. With all due respect to AVM-90 which is a terrific unit, I am not sure if ARC is really the best system to manage monster bass.
There is Dirac ART that is available on Storm processors and should be available on many other brands (but not Anthem) by end of 2024. Many swear this is the best bass management system ever - so called "game changer". I am not going to endorse Dirac claims and have a separate issue with ART, but in the context of heavily oversized bass system, most of my concerns would go away.
Making such huge investment in the subs but limiting them to the ARC is something I would question at least on conceptual basis. There is little in terms of visibility as to what ART does, but I would not be surprised if it could do much more with lesser subs in your room, with the difference being allocated to the AVR/AVP that should support the ART soon, or even Storm (with some additional investment).
