Does anyone know what the ohms rating on an early 90's Peavey 2x15?

    Hi, I have a Peavey 215D-BW cab from the early 90's. There is nothing on the back of the cab that says what the ohms rating is, but the store I bought it from said 8 ohms. This store doesn't necessarily have the best knowledge of music, and this is a pretty big cab, so I thought I would come ask people that actually know ; ).

    If someone could tell me the ohms rating or how to find it that would be great.

    i would assume its 4 ohms, theres no reason for a 2x15 to be 8 ohms.

    Probably a safer bet anyways, better than thinking its an 8 ohms cab then try to run 2 ohms off a 4 ohms head lol.

    You can approximate it by inserting a speaker cord in the cab
    and touching a mutimeter set at Rx1 BRIEFLY to the ring and

    A 8 Ohm cab will read about 6 Ohms DC and if 4, a bit lower than 4 ohms.

    Do not leave connected for any length of time, just momentarily.

    Alternately, pull one speaker out, check if there is a rating
    on the back of the magnet, then check to see if the two are
    series or parallel wired together and do the math.

    I had a late 70s/early 80s one and it was 4 ohms - 2 8ohm speakers in parallel.

    Black widow speakers are usually marked with the impedance so taking the speaker out is probably the easiest way to find out!
