What is your take on high efficient speakers vs. low efficient speakers?

The beliefs around speaker efficiency is sometimes silly. All those numbers mean is how loud a speaker is when driven with 1 watt of power. A 3 watt "flea" power amp putting out 2 watts with any speaker, will produce the same level as a 400 wpc monoblock delivering 2 watts into the same speaker. 

Then again, some people have the erroneous belief that more power sounds better. If that was the case, the very low powered amps would sound terrible. 

My take on this is, that if you are not stuck with worrying about keeping efficiency then you can use components and crossovers that may provide a flatter frequency response without compromise. Often you have to compromise the response to keep the high efficiency. Having said that I think there are good loudspeakers in both camps.  

y’all understand distortion counts as output..in the overly simplistic efficiency measurement…. right ?

You'd want it to be as high efficiency as possible, but if you like the sound of the low efficiency speaker the best, then you get the gear to drive it.

Overly simplistic? Nah , I think people recognize that it is just providing a generalization of the lower power demands of higher sensitivity speakers. People get that. Very little distortion concerns if a 5 watt amp is only providing fractions of 1watt of power at desired SPLs. Well within the low watt amplifier’s sweet spot.
