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


I’ve been watching some electro-voice drivers, from their Vintage Model E-V Six, drawn by the 18" woofers,
original specs say 8 ohms

 here’s a pair of the woofers

1. 2.4 OHMS? My vintage drivers, Crossover, and L-Pads from that era are nominal 16 ohms. I never measured them.

2. Smallish Magnet on 18"? My 15" paper woofers, 15W 37 lbs, have much bigger magnets.  (the 18" are 1/2" thick styrofoam).

3. Mine is 16 ohms, I know they make a 8 ohm version, yet that one shows 3.5 ohms???

Help me avoid trouble by ignorance please,

thanks, Elliott

       btw: I still have a pair each of ST350As (w/new OEM diaphragms), 1824M drivers, 8HD horns, X8 and X36s (all 8 Ohm stuff), left over from the shoppe.

       Always did my own x-overs, but: those from EV: I just couldn't throw away, in good conscience

       I've been hoping to have another room*, large enough to merit the 15" Three Ways, that I used to build, to do Hard Rock justice.            *Doesn't appear likely!

       Speaking of which: if you really want to step up your game, with 8 Ohm 15s: get a pair of OEM, EV Sentry III woofer kits.     Everything will fit your existing 15W frame and magnet structure (NOT the 15SW), but: you'll have a much longer VC throw (more linear excursion), foam surround and less distortion.

I am only finding foam repair kits, you are referring to voice coil, cone, surround correct?

source?

I’ve got a spare 15W ready to go, and a 15W needing a new cone right now that I will eventually repair. I have a 15W coil/cone/pleated fabric surround kit ready for it, but trying this sounds interesting.

Of course I've got spare horns ready, and they can be more readily found in the future by my great grandchildren I hope!!!
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.
