Yes, this sort of OT stuff is real drudgery; but unfortunately, it must be decided and implemented by the true OCD DIY Audio Guy for "best possible performance".
The two options with respect to keeping the horn "conditioned" (temperature and possibly himidity controlled) are: 1) to insulate the horn, itself, since conditioned air from the listening room will get inside it, anyway. 2) Insulate under the rafters and all around the horn, whatever that means, and introduce conditioned air into the space in which the entire horn sits.
FWIW, I would probably opt for #1, since it will be more efficient.
FWIW, I have done projects with both the "closed roof" and the traditional "ventilated roof", and the "new" system projects seem to be doing fine, over several years, now.
I still see no reason why the attic space, itself, could not be well ventilated if the horn were insulated. Is there any reason why a modern, low, full-length ridge vent could not be used? This could ventilate by crossing even the foam-insulated rafter bays. Cor-A-Vent makes several of this type. Just open and screen some holes under the eves, and/or use gable end vents, for that metter. Cor-A-Vent is @ cor-a-vent.com
