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 _________________ Music is probably the most "spiritual of mankinds emotions, and when practised with a pure heart, can lead one into the presence of God, who invented it.

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. _________________ 2 pedal steels, a lapStrat, and an 8-string Dobro (and 3 ukes)

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. _________________ Best regards,

Indeed, Mike. I had the two tests mixed in my head. _________________ 2 pedal steels, a lapStrat, and an 8-string Dobro (and 3 ukes)

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. _________________ 2010 Rains 3x5 SD10, 2006 Rains 3x5 SD10 Powered by Quilter Tone Block 202 and 15' and 12' Custom Speaker cabs |
