Do I have this impedance right?

Discussion in 'Amps and Cabs [BG]' started by The Alexander, May 12, 2006.

  1. My cab has two speakers with an impedance of 4 ohms each. This makes my cab have a total resistance of 8 ohms, correct?

    It depends..... are they wired together in series or parallel?

    Most cabinets like yours would be wired in series for an 8 ohm impedance. If you have a multimeter, you should read around 6 ohms resistance for an 8 ohm cabinet.

    If you dont have a multimeter you can also find out by ckecking the cab wiring.

    If both your (4ohm) speakers are wired in series, its a 8ohm cab.
    This cab wiring method will have a wire looping through one speaker to power the next, then back to the input jack.

    If your speakers are wired in parallel, Its a 2 ohm cab.
    Both speakers will have a matching, (+ and -) conection to the input jack.
  4. Thanks for all the help, guys. I looked at my speakers again and apparently they are 8 ohms instead of 4. They are wired in parallel, so the resistance is 4 ohms?

    Yup, it's a 4ohm cab.
  6. Thanks!
