Not having any idea what the hell I was doing when I designed my own servo amps back in 1997, I gave them WAAY too much bandwidth. The torque loop is certainly good to 10 KHz, at least. I hooked up a dynamic signal analyzer (an instrument for making frequency/phase response graphs of closed-loop systems) and found the servo motors made SURPRISINGLY good speakers. I don't have a way of injecting real audio frequencies from G-code, but if you fed audio into the servo amp's input, I guarantee sound would come out.
