have recently been thinking about efficiency. Apart from enabling you
to use low power amps, is there really any reason why high efficiency is
better than low or medium efficiency, all else being equal (and I know
perfectly well it never is, but let's assume it is for this thought
experiment)?
It occurred to me that historically, the advantage of high efficiency
drivers was that they tended to be optimized for low mechanical loss.
Low mechanical loss tends to make the sound cleaner, more detailed and
more "free" than from drivers with high mechanical loss, a chassis
designer told me. It is now possible to buy normal efficiency drivers
with low mechanical loss. So, is there a reason to put up with the
demands of hi-eff drivers anymore? |

Actually if I have time I would probably write up MS Word’s 4-5 pages
long of articles with arguments WHY high efficiency is conceptually
better and why any extra dB is juts at opportunity. The way to get and
the way to use high efficiency is another subject but with all things
being equal higher efficiency is better. It is a bit unpleasant that
high-fight industry (here I come again!) did not advance the subject and
education of public about high sensitivity because they do not do high
sensitivity. The industry deployed to public bogus theory about
relationship between efficiency and power of amplification and everyone
feels settled. Do not be mistaken – the high efficiency itself is not a cure-all
solution and it does not resolve all problems -rather creates them.
Still, there are so much “new” this that is “possible” at high
efficiency! Regardless the design of your car a high octane gas will
prose better drive, will it?
