MG-20

Magnesium Compound Loudpeakers





Esoteric's new speaker systems incorporate a new technical application of magnesium alloy (96% Mg), combined with a specialized ceramic coating. The MG-10/MG-20 loudspeakers are manufactured using Esoteric's Mg alloy for both woofers and tweeters (including dust caps). This exclusive design features exceptionally high resolution with crystal-clear transparency; free from metallic, carbon fiber, Kevlar® and paper coloration often associated with other driver materials. This lack of coloration is due to magnesium's high internal energy dissipation and magnesium's well known acoustic neutrality. This technology was developed by Esoteric's sound engineering department and manufactured jointly with Nippon Kinzoku. Final acoustic tuning, manufacturing and assembly takes place under Esoteric supervision in the UK by world-renowned British speaker manufacturer, TANNOY Ltd. This unique technology has recently been honored as an "Innovations 2008 Design and Engineering Showcase Honoree" by the Consumer Electronics Association.
