I 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?
