So interest has been expressed in more comprehensive power testing of amplifiers going beyond just resistive load. Audiograph makes such a box for automated testing but the retail is north of $25000. Way too much money for the limited use we will get out of it. But you do get cool graphs out of it:
First question is whether what they are testing is the right set. I personally don't see a reason to go down to 1 ohm.
Is +-30 and +-60 degree phase the right targets? What is typical in speakers?
I don't mind spending the money to build one if others chime in with the design and questions like above.
