Amplifier stability with very low impedance, high efficiency mid/tweeter section???

I've been looking for this information everywhere but can't seem to find a clear cut answer.  I understand that a very low minimum impedance like 2Ohms is a very difficult task for most amplifiers to drive and may even damage it.  But it's also my understanding that this is a current, not a voltage problem.  In other words, say we had an MTM speaker that was used ONLY as a midrange from 200hz up, so it wouldn't have to play bass where most current is required.  And say it also has a very high efficiency of 97db but also a very low impedance of 2 ohms.  Would this be a problem for most amps?  Could it damage the speakers? I'm thinking no since the amplifier wouldn't have to put out much voltage or current to output sufficient SPL.  But what's the actual answer????

My answer you found humorous was funny yes but intended to make a point and get you thinking. I mean actually really thinking not bandying words about which is all that is going on now. No progress being made towards answering your question, which except for one detail was pretty well thought out.

The "for example" you are talking about, a MTM array used 200Hz and up, is of course what Tekton does. If you want to make this a guessing game going round and round nobody ever really getting anywhere because nobody really knows what you’re talking about, you don’t need me you got the right guys on the job already.

This is the point where usually I would give some deal clinching examples of precisely why they are the right guys for that particular job. But not today. If you want to know why it is no problem at all for your amp or any other, in fact is an advantage inherent in the design that helps explain why they sound so doggone good, let me know I will fill you in.

I am old school. If your amplifier cares about the speaker I say look, you're an amplifier, this is your job, tough luck. If you want it easy go back to school, learn how to be a AVR, nobody cares as long as you have a lot of knobs and switches and stuff. But for now, get on with it.

I did lose one to Amplifier Protective Services but that was before I learned to not let them have a cell phone. Take my advice, make an example out of one, word gets around fast, you won't evert have any amplifiers whining about how hard you work them. Trust me. Haven't heard one word of complaint in 20 years at least now.
