Klipsch Pro KP-600

This was the most expensive pro cinema speaker Klipsch ever sold. I've heard this system and I was wondering why isn't this in clubs today. It was a very hi-fi sounding pro system. If I were to ever own a club or have a hand in selecting a club system this would have to be the one. Are these too big for my room? Can a speaker be too big for a room..... Nah.
