Strange Speaker-Ohm Reading

[Rising Farce]

I just popped a couple of 8-ohm EV Black Labels into one of my Mojotone 2x12s and wired them in series. But instead of metering at around 14 ohms, as I would expect, they're showing 10.4-10.6. (I took the measurement using the old multimeter-and-plugged-in-guitar-cable method.) This isn't necessarily an issue--I can just run the amp at 8 ohms instead of 16--but it does seem strange. Any ideas?

If I remember correctly the EV do read much lower than 8 ohms. I think mine read like 5 or 6 ohms.

Measure them each and see what each one reads then double that and that's probably what you will get. It's normal for speakers to read 2-3 ohms below what they are spec'd for.

Most 16 ohm celestions read 13.0 13.5 ohms not 16 exact on the money.

Set your impedance as normal at 8. An amp set to 8ohms into a 16 ohm impedance load(speaker cab) is a safe mismatch and actually takes some stress off of the output transformer.

I'll do that. Thanks for the input.

Impedance is not the same as DC resistance. It’s frequency dependent
