Is the most efficient speaker the best speaker?


Is the most efficient speaker the best speaker -- all other things being equal?

After the correction the linesouce in the eg would not give anything up to the SET setup and will still have more dynamics..97/99

I would love to hear your informed opinion. I`m no speaker designer nor an engineer, but I just don`t believe weseixas`s numbers are accurate in the horn/planar comparison. At least they don`t match what I have heard in my experiences concerning sound pressure(not comparing sound quality issues).
I have found that using efficient speakers, besides the wide dynamic swings, is the ease of use of a smaller amplifier, which sounds so much more natural and detailed than a much larger amplifier, of the same design topology, imo/ime. This has not been the case with speakers of low to medium efficiency, where the larger output amps are more desirable.
