Re: Audio in the Movies

I recently encountered the HPS-4000 theater speaker system for the first time at the General Cinemas googleplex in Framingham, MA. I agree with Clark, it's very impressive. General Cinema even gives out a pamphlet on the sound system.

My all time favorite theater sound system though was the Cerwin - Vega "Sensurround" folded horns from the early 1970s. Somewhere I've got a spec sheet on those, I think they used 2 18" woofers in each cabinet driven by 750 watt or 1 kikowatt power amps. With the mouth extenders in place they were supposed to be able to reach to something like 5 Hz at 110 to 120 dB.
