I spoke with John Iverson within a few days of his disappearance - just two weeks after my conversation with him, the local dealer told me he was missing. I forget the year - late 80's or 1990 at the latest. As I recall, the U.S. had just signed the INF treaty with the Soviets, and John was pissed about that (I might be confusing an earlier conversation). Anyway, he was most pissed at the FBI for raiding his place and confiscating a project he was working on. Piecing together what he told me and what the local dealer said, it seems he had submitted a patent for a loudspeaker that the FBI believed used stolen "Star Wars" missle defense technology. I think he had essentially built a particle beam generator, and had developed it into a massless driver, perhaps reminiscent of the old Hill Plasmatronics. John had put over a year and a couple of hundred thousand dollars into the project, and was outraged that the FBI showed up after he filed for a patent and confiscated all his work and related files and documents. He basically said to me, "Why would I steal defense secrets and then try to file a patent? Who would be that stupid?" I don't know if this is connected to his disappearance, but I wouldn't be surprised. I keep hoping he'll show back up one day, fiery as ever, god-damning the government and the commies and everyone else and going back to building amps that you can literally weld with (he drove around the country with the prototype of the Eagle 2 in the backseat of his car, and part of his demo was to short the speaker leads together and hold them there while the copper sparked and melted). I think of him every time I turn an amplifier off - you could unplug the Eagle 2 and it would play for another 40 seconds. His disappearance is x-files stuff. And, I miss him.
