I just acquired a Nashville 400 cqabinet loaded with an Eminence 15. The only numbers on it are 451549-18 and 7DE-251. Is this a 4 ohm "15 C that is mentioned in many places on the Forum? Thanks for any help on this, Lonnie

Every one should have a digital multi-meter and you can get a basic digital readout with ohms, continuity and voltage for low $$.
An 8 ohm speaker may read under 7 ohms and 4 ohm speaker may read 3. 5 ohms or so. This is normal. You can also check batteries and connections and have it the rest of your life. Cool.... |

Len,
For the less tech inclined out there, what's the method for getting a digital readout with ohms on a digital meter? |

Set meter to resistance scale
Put one lead on one terminal of the speaker, touch the other lead to the other terminal.
It should give you a reading pretty quickly.
Those wires are thin, if you leave the leads in too long, you COULD overheat them, speakers aren't meant for DC.

Just for accuracy, the current from an ohmmeter/voltmeter is quite small and can't harm any speaker voice coil.
Now if you were using a battery, like a 9-volt, to test whether a speaker is functional, it could do some damage if it was held on the terminals for more than a couple seconds....you're actually only looking to hear a pop from the speaker with a test like this.
Also, select the lowest resistance scale on the meter. It will give you the most accurate reading.

Indeed, Mike. I had the two tests mixed in my head.

| you can get a real low budget meter at Harbor Freight for less than $10.00 but I would spend a bit more and get something of a better quality. |

If you watch the periodic coupons, you can get a multimeter for free at harbor freight. Not high quality, but good enough to measure speaker coils with.

Lonnie back to your original question...YES that is the ESP 15C 4 Ohm speaker that has been discussed in depth here on the forum.
