CSP stood for "Commercial Sound Projector". They were made in the mid to late 70's. Before that, their PA cabs were columns.

I always questioned why they used a 15" and a 12" sharing the same airspace as well.

If I'm not mistaken, the crossover was a simple High-Pass filter for the horn, and the woofers ran fullrange.

The HF driver was an EV 1823M, basically a siren driver with not much response above 8kHz..

It was a midrange screamer.
