Given the nature of this forum, I suspect that many of us have gone out on a limb more than once, trying to build/find a better mousetrap. I have a question for you. What was the craziest or most unusual system or piece of gear you ever owned or made? Let me get the ball rollin here. In high school, I got ripped off by the local HI-FI salesman by being talked into a set of Johnzeer speakers. The sudden realization was that these were crap, and only looked cool(to me). After the sting wore off, I started my journey into real HI-FI, and came up with a kit from Speakerlab. It was a folded horn design that didn't sound great, but the bass is unforgettable! ALL the way down to 20hz with force. It took about three months to build them in shop class, and I got an A- cuz the instructor had no idea what the Hell they were. At 170lbs. each, they looked more like refrigerators with wood fronts. But in the end, I sold them a couple of years later. Wish I knew then what I know now.
