muRata ■ ES103A ■ super tweeters

This is the legendary super tweeters which the production has been stopped.
Re-production of high frequency needs hard-core high technology (not the same as making main speakers.)

muRata is a high-tech electronic giant in Japan, and producing such super tweeters was due to some interesting reasons from a very senior executive....

Condition is fair. There is a scratch on the wooden part of the body. (Please see all photos for condition)
Original metal case is included.


I am letting this pair go because I am downsizing my system to reduce my HiFi fever. (On sale in other listing is a pair of Harmonix HS101-SLC Super Max super tweeter cables which has been driving this pair of ES103A. Please check them out)

“…The muRata Manufacturing Co., Ltd. is not your typical audio manufacturer. muRata as an 'Innovator in Electronics' supports the infrastructure of our electronic society by developing new electronic components and technologies." Don't believe it? muRata was formed in 1944. Their revenues for 2004 were roughly 4 billion US dollars. If you want to find their super tweeters in the company's annual report, you'll have to look in the "piezoelectric components" category - and I suspect we're talking a tiny fraction of income. You see, the ceramic spherical diaphragm that is the breath of the ES103A was an offshoot of some R&D into a core product line - piezo-electronic ceramics. We are talking high-tech and high budget R&D to the tune of $300 million plus last year. The notion that someone within the muRata ranks thought to spin off a line of super tweeters amidst the millimeter wave radar modules and piezoelectric vibrating gyroscopes is pretty darn fascinating...."
