Don't forget air ports. Subwoofers need a lot of air, and they can be
damaged by the pressure difference between inside and outside at higher
volumes. (Don't ask me how I know)

Can you describe that? Serious. I have seen speakers blown by too
_little_ back pressure (over excursion) caused by ducts.

What happened?
