    Hey Just curious what a 4 ohm + 8 ohm cabs combined impedance would be?
    I've got a Eden WT550 that can handle 2ohm loads, so got it covered.
    Just curious as to the above question. :bassist:

    Lemme see if I can type it

    Parallel ohms calculation where cab 1 is R1 at 8 ohms and r2 is cab 2 at 4 ohms:


    ohms= 1 / ((1 / r1) + (1 / r2))

    ohms= 1 / ((1 / 8) + (1 / 4))

    ohms= 1 / (.125 + .250)

    ohms= 1 / .375

    ohms= 2.66666666
