Drive Sirens!!

I seem to recall a line from Kurt Vonnegut, maybe Slaughterhouse Five 
about the air raid siren removed from Berlin, and relocated in the 
midwest being driven by a  Messerschmitt V12. My guess is the 94A is 
real, A big sound requires lots of energy, the "referigerator" Altec S1A 
dual drive bass horns we made for a sound company can accept 2kW each, 
we put two on each side of an outdoor stage at 8kW total 120V that's 
66A. They sounded pretty good at 1/4 mile 90 degrees, the siren has to 
project farther than that at 360 degrees.
