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

rodman, all

I just noticed, that pair of EV-Sixes near me: it's a pair of identical Mono Boxes, they are not mirror images like Stereo Pairs are.

clearly it's hard for me to keep my eyes off them.

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.

have a good look inside

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.
