My biggest issue is I have long runs from my amps to the speakers at approximately 60 feet each.
Your listening space is over 120 feet long? This I’ve got to see. Post a photo!
I’d use a custom fabricator btw. Most will work on special order. PM me if you need references.
(PS: Before a spectrum commentator objects, I realize that as described the space may be less than 120 feet long. However, it may well also be longer.)
