I was at this event over the weekend and they had these white Klipsch speaks (3-way) with what looked to be 12" drivers and two 1" deep ports on the bottom. The MF and HF horns blew and now only the LF drivers work. They were powered by a QSC 1500a. I'm interested in finding out what speaks these were and maybe I didn't look hard enough, not sure. Thanks.
