Default Re: The Audiophoolery Thread.

With serious engineering effort professional speaker makers have done a fair bit better than 2%. My Yamaha NS1000s, which show what a really big corporation is capable of when it is prepared to throw enormous amounts of money at a problem, got second and third harmonics down into the 0.1% regime above 500Hz and were still only 0.3% at 100Hz (measurements taken at 90dB at 1m). The intermodulation distortion wasn't significantly higher. Not bad for 1970's technology ! Among other things the production of the beryllium domes for the mid-range driver and the tweeter made the speakers uneconomic though, and Yamaha eventually threw in the towel on them for business reasons.

Cheers,

GJ
