Yes the diaphragm is toast. The coil is apparently "open". You can not tell by looking at it that it is bad, but the multimeter does not lie. Get new diaphragms from Great Plains Audio. Probably not cheap, but keep in mind that any money you put into these speakers is a safe investment. You should have no problem getting your full investment back.
For the L-pads from partsexpress you want the 100 watt model. You have four choices, 8 ohm or 16 ohm, 3/8" long shaft or 1" long shaft. The L-pad should be marked on the back as to what the ohm value is. They are most likely 8 ohm.
Good luck.

So the diaphragm is bad? I don't see any cracks or damage to it. I don't need a new driver because the coil is open? Since I'm replacing one should I do both? Before the horn went and after I cleaned the L-pads I can see how these speakers can blow away any other speaker. The bass and mid-range was phenomenal! Made my HPM-150's sound muddy. I think this could be my last set of speakers.
The coil is integral to the diaphragm. The diaphragm itself will look fine but there is a break somewhere in the coil winding.
Yes, do replace both. Contact Great Plains and they will help you get the right parts and answer any questions. You could also send them the drivers to be restored. They recharge the magnets and replace the diaphragms.
I'm glad you like the 19's. You got a great price on them.
