    That's an awfully odd impedance. I'd bet you could pull it off without blowing anything up. The 4ohm rating is the "legally let's cover our a$$" rating.

    hmm okay:) but will it have an effect on the sound quality?
     
  4. I would say stay away from that combo. With a SS head it is fine to go above the rated impedance, but going below isnt the safest thing.

    Sound quality? Nope. It will be slightly louder than a 4ohm cab.
     
  6. If the head survives.

    A lower impedance will draw more current through the amp. Its rated at 4 Ohms as a minimal impedance.

    The cabinet is probably 2.66666666 ohms on paper, so they advertise it as 3 ohms. I'd stay away from the head/cabinet combination you've asked about.
    In reference to the quote above: You can't measure impedance on a standard multi-meter. Impedance is frequency dependant, DC resistance (what a typical multi meter measures) is not frequency dependant. A speaker's DC resistance is lower than its impedance because
    z=R +X[SUB]c[/SUB]+X[SUB]L[/SUB]
