Post Subject: An active thermo-stabilized blanket around back chamber?Posted by Romy the Cat on: 10/23/2009

Miab, I have very limited knowledge in construction techniques, moist prevention and how all of it might affect a big horn. My very uneducated production suggests me that it is not truly a bid deal, but of cause if go this route then I certainly will consult with specialists.

Still, the back of the horn is sealed, with strong walls. What is differences my driver sit not in box in not climate controlled storage or if it sit inside the horn in attic” I think it the same. In fact in horn it has some ventilation via the mouth. Yes, attic cone run very hot (bad for ALNICO magnets) and might go cold. The cold 15” driver would have stiffer suspension and different Fs and Q. Still, I do not think that it might be terminal or dangers for a driver.

Nevertheless, it might be a good idea to THINK about it. Perhaps it would make scene if the driver in attic or outside to put whole back chamber in thermo-protective cocoon? There are some polymers that can run hot or cool from very low voltage and I have seen some thermo-stabilizing pad were made with them. I guess they might exist in shape of blanket… A good idea to think about it is the back chamber will be exposed.

My primary concern is not driver but the horn itself. If it will be attic and let say 12 feet horn will be made from “young” wood then after a year of sitting in attic the wood will be “loosing it’s youth” and the horn would need some “help”. I do not know, I need let professions to consult me about it.
