Another +1 for drubin's observation. I just read a href=http://www.6moons.com/audioreviews/kef3/1.html>6Moons
review of the KEF R900 where the reviewer summarized this observation
very well:
... to which I'd add the more widespread use of neodymium magnets, curved
cabinet profiles, better bracing, longer excursion surrounds, and near-exotic
light and rigid diaphragm materials such as the Monitor Audio CCAM
(ceramic/magnesium) drivers. Their Gold Series even uses CCAM ribbon
tweeters in a $5.5K and under series.
review of the KEF R900 where the reviewer summarized this observation
very well:
Progress over the last few years has favored
loudspeakers the most. We have better mathematical insight into bass tuning.
There are driver design and production advances not least due to the widely
embraced Klippel measuring system. Theres the lure of cost-effective
offshore production where China today offers true hi-tech kitted factories.
This can add up to manufacturing tolerances and precision which until
recently involved costly extravagances and rare engineering savvy. As a result
the category of speakers has reached an impressively high state.
