I'm an avid hobbyist and retired pro audio guy. I do mostly private R&D and fabrication. I have been obsessed with sound reproduction since 1982.
I spent 7 years of my life doing R&D for Harman International and Harman/Becker. I was the dude that did the torture tests on the 1st 1000 Kappa Perfect 10s and 12s. (The cones burn a real pretty green color haha).
I build horn and hybrid tube enclosures (3rd and 4th order) for fun and some servo motor structures. Just another audio nerd.
I collect Proton, Adcom, Dennon and pre pansy era Fosgate equip. PM or mail if ya wanna sell some.
