I thought this thread was going to be about the Morel drivers.
Last year I spent a good couple days pulling the hf's out of Clair UB-2003 speakers, and loading new ones into them in the middle of the night. This was done at the top of a ladder during bad bad bad weather. Oh by the way, it was in a lounge on a cruise ship going around Cape Horn, the water between South America and Antarctica.
It was one of the few times I was glad speakers have magnets, otherwise the screwdrivers and allen wrenches would've kept falling off the ladder. They lasted only a few months from what I hear. Oh well, not my problem anymore.
