low efficiency speaker vs. high efficiency speaker?


What are the advantages and disadvantages of high efficiency speaker vs. low efficiency speaker? Does it mean that 93db efficient speaker will sound better than 86db?

Hi,
there are some very interesting answers. Maybe I can give an experience from the musical side. I used Planars, then dynamic speakers and now I use horns. Let's see it from speakers who does it right , no matter of construction.
With low efficient speakers you need some powerful amps to control them in every area. Powerful, when you want to hear every detail even with low volume. When you want full dynamic with low volume, then there is the first problem. Very difficult.
Next : Powerful amps are everywere, good sounding ones are available too, but the combination, powerful AND Good sounding is rare and normally not cheap.

With high efficient speakers there it is much easier to match this one with a good sounding amp. No matter solid State or Tube. Much more amps sound much better when they don't have to deliver all they can give.
There are people out there who believe that the first Watt is the most important, but this is another story.

So, you get much more satisfying listening results with such a combination when you want ( or have to ) listen with low volume.

You hear normally much more microdynamics and an absolutely effortless reproduction of music.
Sometimes when I listen to Radio ( MD 108 ) I am totally amazed when I hear the singer's breathing. Via Radio !
It's on the source.
My speakers have 99 dB and I use them with Pass mono amps ( 100 W per side, normally a total overkill, but it works excellent ).

The feeling of " being there " is with such a speaker really possible.
