50 A power amp? What kind of monster is that?


Hi folks, I've read that some power amps could deliver 50 A!! Well, that is the current for welding. You might need the capability of delivering such extremely high currents when you are using very low efficiency loudspeakers (let's say 87dB/W/m). Most of the energy will be sucked up by the crossover. My question is: when the amp is passing through 50 A of current, how can a speaker's crossover survive such a devastating energy boost?

My speaker is able to take 1000 watts for a millisecond and since the croossover is inline. It just passes the power on through to the drivers with no ill effect on itself.Aball is exactly right and thats as current as we can make it!Take care Dennis
