I would like to use my 1005b horn with my little portable PA system. I read, on this site, the Altec catalog pages where they package an 805b horn in a box for road use and call it a 1225A. They say that on its own, "a multicell is delicate and fragile," thus the protective box.
Well, I've got a box around my 1005b horn, but I'm wondering if I need more protection for my delicate and fragile horn. To this end, I was thinking of bringing my boxes to work and filling it with the expanding foam stuff in the shipping department. Our packaging engineer thought the expanding foam might not be too hot, since it hardens to be quite stiff and will transfer impact engergy to the horn. He also said the expansion has quite a bit of force and may bend or otherwise damage these fragile horns. This gives rise to a couple of questions:
1- Is expanding foam a good idea, or pure bonkers?
If so,
1a- Should the foam be allowed between the cells?
1b- Should the cells be isolated from the foam by plastic?
2- Would soft foam cut to size be superior?
3- Anyone got any other good thougths?
Here are a couple pictures of what I'm trying to provide protection to, and what the box looks like.
Oh, and thanks for any comments.
