...powering the more efficient speakers?

My two cents is Story has the answer for you. Somewhere in the speaker's impedance curve it dips too low for the amp. On solid state amps, the output voltage at a given volume stays the same regardless of impedance, but the current draw changes. A 4 ohm load draws twice as many amps compared to an 8 ohm load, and a 2 ohm load tries to draw four times the current compared to 8 ohms. At some point, the amp thinks it is seeing a short circuit and goes into protection mode. Some amps handle this situation better than others.
Yep and as already mentioned by others, high efficiency isn't much of an advantage if the amp still has to deal with a nasty impedance curve. If I liked the offending speaker, I'd simply buy a better amplifier.
I did not buy amplifier for the JBLs but wanted to hear it on them since they are my reference, so it's not a problem. The amp is driving the Definitive Technologies just fine. I'm just surprised the outcome came out the way it did.

Just be glad that your amp has that protective circuit. I've repaired a few of the old McIntosh MA5100 and 6100 integrated amps that if they saw a 2 ohm dip, they would blow out a zener diode.
It was a little secret that Gordon Gow's son told me.
