Electrovoice 18" Woofer: smallish Magnet; only 2.3 ohms?

rodman,

how close to Plainfield New Jersey 07062 are you?

E-V says no parts or help with 18WS available

I have four pairs of electrovoice speakers and none of them measure that way. The dc resistance is way higher than that in all cases so i would be leery of a fake 18 inch woofer for sure especially if the magnet is small, ev did not use small magnet assemblies in any of their woofers.

they are original E-V 18WS Woofers, used in both the E-V Model Six and the Royal 400 models.

I have not come across all specs of the 18WS, but these are genuine IMO.

Royal 400 Specs: 8 ohm impedance, 4lb-10 oz ceramic magnet, which is why it appears so small, compared to my 15W's physically larger Alnico type magnet at 5-1/4 lb.

DC resistance of my 16 ohm 15W is 11.6 ohms; the 16 ohm 15Wk (klipsch baffle version) DC resistance is 3.2 ohms,

then, when buying replacement 15W, I will need a DC reading to verify it is not the K version. Seems they simply stamped the label with a lower case k, and who knows who has replaced a voice coil???

I'm gonna measure my spares someday.

       No one is going to have OEM/EV Sentry III reconing kits, except EV  or an authorized EV warranty center..

        Anyone else would be proffering aftermarket, junk parts.    I'd never consider that an option!
