    Simply out of curiosity at the moment:

    What is the maximum output voltage for a thunderfunk TFB-420 ?

    Dont know? How about an Eden WT-300? Or...

    It is not unusual to have max output voltage specs for audio poweramps, however the bass amps are listed in watts. Yes, P=I^2R, P=VI , P= (V^2)/R , but why not list the actual output voltage as opposed to the calculated (at some value) power?
  2. It's always [not] about the Watts, baby.

    This doesn't take into account the reactive load of a speaker and is really only good for rough estimates. A 400 watt amp at 4 ohms is 40 volts. I hope that other more knowledgeable TBers chime in with better info.
    (this is also not the peak output)

    OK, I get what you are posting, however it's really backwards. An amp doesnt put out watts per say. Power is only calculated across a particular load. An amp does, however, have a maximum voltage... (that can cause current across the load).

    Why do amps list the result of the calculations put through the filter of assumptions instead of simply listing the max output voltage?
