I'm such a jerk I didn't think of such an application for the environment chamber. Yeah I can see it now, guy orders a set of M80se for xmas and they sit in a Puro truck over the weekend at -30. Dude is anxious to fire them up and they seem warm, MDP warms much faster than the metal parts, and the drivers could be affected. Interesting the affects on ferrofluid Ian documented. Perfect for outdoor speaker testing also... duh I never thought of such use. It's also one really neat thing to have in a lab!
