I was in this club the other night, Lakeview Links in Chicago, and they had this (I think) PA speaker thing. Looked like a folded horn enclosure, but with several revolving doo-hickey's in the front of each of the sections. Also, attached to it looked like a tube amp of some sort, as there were a bunch of exposed tubes. It was the craziest thing I've ever seen and I wish I had the chance to talk to the sound guy but I didn't. Anyone know anything about this?
