Oh no! Man, I feel bad that this happened to you, Gary. That must have been very disappointing, on so many levels. What a bummer.Sigh! Mishaps happen. But it had to happen in the middle of a tape demo Myles was doing just when the crescendo of Hope by Hugh Masekela hit. On tape. With huge dynamics. The volume on the prototype preamp went to maximum. Not good.
Luckily, I had tweeter protection, and under-hung voice coils so the voice coil didn't bottom out. But the metal cones bent enough that I could hear the damage. Soundstage, the separation of images from the speakers, and all the magic of those speakers were lost.
