See post 7, ballpark 2 to 14 ohms. If it's outside that it's almost certainly bad.

Yes, the end of the cable, so you are measuring resistance of the speaker itself and not something on the motherboard.
Yeah, nothing. My multimeter doesn't register any sort of change either when I put the probes in the end of the cable or when I touch it to the + and - of the speaker itself. So maybe speaker is toast? Of course, my old, cheap multimeter is difficult to read. Can you confirm that I have the right setting on it?

I think that setting should do. Touch the probes to each other and if you get a 0 or near 0 reading, then the meter works and your speaker is toast 
what about the capacitors? I had the same issue with a SE/30, I'd closely check the capacitors and in case of doubt I would replace them all
Recap is a good place to start with a machine of this age for sure, but if the speaker isn't reading any impedence it's blown.
If the speaker isn't blown I would first reflow the logic board connector. However since it probably is, I would try to find any 4 or 8 ohm speaker laying around just to test for the boot beep. At that point you're looking at putting a connector on the temp speaker to test, or jumpering wires to the pins to hook it up.
