An electrostatic speaker uses very different technology from the conventional circular or oval types we’re used to. Whereas conventional speakers have a relatively bulky and heavy moving magnet to activate a diaphragm that moves air and thus creates sound, an electrostatic speaker has an extremely thin multi-layer membrane sandwiched between two electrically conductive stators.
These were primarily intended for use by recording studio engineers but have since been embraced by discerning audio enthusiasts, have won more than 30 awards and are widely acclaimed as “the best headphones money can buy”. They should be good, mind. The ultimate model, called Aperio, is hand manufactured in gold, comes with a custom amp and sells for a cool £30,000 – only in Harrods. This perhaps gives us a helpful clue to the automotive sector WA will initially target.
Other advantages? WA’s easyto-position electrostatic speakers are particularly suited to noise cancellation applications because their low-mass membranes respond very quickly and precisely to changes in ambient noise. They also suit the creation of personalised sound zones for a car’s different occupants, a customer demand that is just beginning but likely to increase.
