    Hi,

    A friend of mine had an SWR Goliath Jr II cabinet he was looking to sell. The only problem with it is that the crossover network needs to be replaced. So I picked it up from him. All the speakers work, and the thing sounds awesome, even without the tweeter.

    As I was packing the cabinet into the car, I asked him how many ohms the cabinet was. He didn't know.

    I have an 8 Ohm cabinet and now this one. I want to know the impedance of the cabinet, but there are no markings on the backs speakers, not even the tweeter. The back plate of the cabinet doesn't say.

    Anyone familiar with the cabinets? Is there a test I can try? I'm pretty sure that running a meter across the leads of the speaker won't tell me anything.

    Thanks in advance!
    Tom

    So they only made it in 4 Ohms? Well, that's convenient! Thanks!

    Yep, only 4 ohms.

    I've seen them in 8 ohms before.

    Get a cheap multimeter at radioshack, lowes, Home depot, etc and measure DC resistance. If you get something around 6.2 it's an 8 ohm cab. If you get something around 3 it's a 4 ohm cab.

    It will tell you the DC resistance of the voice coil, which is always a little bit less than the 'nominal' impedance of the cab.

    2.7 Ohms. Thanks for the tip!

    Hey, everybody -- I really appreciate all the replies. Thanks!

    The Goliath Jr II were only 4 ohms. The Goliath Jr III were either 4 or 8 ohms. That being said, I bought a Goliath Jr II that I assumed was 4 ohms but discovered the person had replaced the speakers making it an 8 ohm cab.

    4 ohms only, but you can rewire it to 16, which depending on what your 8 ohm cab is may be a better call (do you want your other cab to carry 2/3 of the signal, or do you want the goliath to carry 2/3 of the signal?).
