And if you're really nice, I'll even turn on my subwoofers while you're here. (inside joke for those who remember the initial audition mishap)

Thanks Jason, I might actually take you up on that, however, I have to say I maintain a great deal of skepticism about it being the M80s, I mean Axiom wasn't born yesterday even if these particular speakers were, and would probably test those last.
I'm more concerned that there could be something wrong with my setup or electrical system that is causing the amps to fail at high volumes, and if I try something like Outlaw I would find myself in the same lower mansion of hell.
A straightforward approach would be to go ahead and order a 3808 so I could know where I stand but that would be a costly option if I continue to pursue an HT build involving separate power amplification, I'm still stuck on that idea so I hate to rule it out just yet.

If the Rotel doesn't shut down at 3/4 volume then that tells me the Emotivia is a defective unit. The Yammie just isn't up to the task and not a receiver in which Axiom recommends for the M80s.
It's not your wiring, do you use a microwave? Does it shut down? If not then don't worry about the wiring, that takes far more amps and is harder to run than the amp.

OK thanks once again everyone, I know this has gotten tedious, bear in mind I don't even have a working pair of front speakers!
It's taken my mind off the wait for the rest of the system though, that seems the least of my problems at the moment.

if the concern is the minimum impedance, the question has been answered. That was my read of the NRC data as well, however thanks for the technical anaylsis.

No, as Rick commented, the problem isn't the electrical system; it appears that on occasion there's too much power, rather than not enough. One thought as to possibly a problem with just one of the M80s: connect just one at a time and run in mono on that program material to see if it shuts down when driving one M80 but not the other.

bear in mind I don't even have a working pair of front speakers! Sure you do, you just need an amp that works other than that nice Rotel you have there.

Now if only the folks at emotiva could come up with some ideas!
It does seem to be mainly when their high wattage amps are driving 4 ohm speakers that the protection fault crops up.

Well I have tried with just the left channel because the right input seems a bit loose, but the fault has been split more or less randomly between one or the other channel going into protect, which leads me to suspect even more that it can't be the M80s because they can't both be bad, which would have to be the case if the protection fault would shift from side to side, would it not?
