That's a point I hadn't considered. Low impedance easily drives most amps into clipping, generating square waves who's harmonics filter up to the tweeter, blowing it.
This would generally lead me to believe that whatever amp I choose, it should have a stiff reserve cap in the power supply. This then leads me to believe that amps like the McCormak DNA-1, with 64000 microfarads of storage might be a bit weak. Perhaps the McCormak's have a soft clipping feature which would prevent this from happening. Am I on the right track here?
How about the Classe 15 or Classe 100? These both double their power into 4 ohms and the 100 model is right in my range.
Thank you
