Impedance on my cab is 6.2Ohms

    I was just playing around with my Yorkville 210 cabinet and for no reason at all decided to measure the impedance. It said 6.2 Ohms. That cabinet is supposed to be an 8 Ohm cabinet. The cabinet works perfectly. Is there an agreement between manufacturers to say that a cab is 8 ohms or 4 ohms even if their impedance is off by an ohm or two? Or is there something wrong with my cabinet?
  2. The figure you got was the DC resistance. The actual impedance varies by frequency, since speakers are an RL circuit (and there's a crossover in there anyway); the "8 ohms" or "4 ohms" figures you commonly see quoted are average figures over a range of frequencies.

    No, its very common for speakers to read different than there actual rating. Someone more techy than me can explain it. As long as the amp sounds ok and is not running too warm, it should be just fine.

    when you check the impedance of a cabinet it will bounce around but should be about 3/4 of the stated impedance. i.e. 8 ohm cab = around 6; 4 = 3 on a DMM... in other words it's what it is stated to be...
