Completely Transparent Electrostatic Speakers for Car Audio
For over 30 years our engineers have been working to perfect the process of traditional electrostatic speaker design and manufacturing. Since the company's inception in 1983, our products have garnered critical acclaim from discerning consumers and won a myriad of awards from industry pundits for their stalwart commitment to manufacturing the most richly detailed, revealing, and emotionally engaging loudspeaker experience in the world. Those innovations have resulted in amazing technologies for home theater and stereo listening such as the Curvilinear Line Source (CLS) XStat Electrostatic Transducer. Unfortunately those advancements and technologies has never been able to fit inside of an automobile...until now.
Experience MartinLogan On The Go
MartinLogan is perfecting a new technology, called VaporSound™, that makes it possible to coat any glass surface inside of an automobile with a conductive electrostatic speaker to create an enveloping sound environment, with no visible drivers or unsightly speakers in the car.
We think it's going to revolutionize the car audio industry.-Joe Vojtko, Chief Audio Technologist
VaporSound™ Transparent Technology
Our in-house design and engineering team have developed an innovative new patent-pending process of vapor deposition that enthusiastically impregnates a uniformly conductive surface onto a specially manufactured and completely transparent thin-film diaphragm. As shown below, this diaphragm is laminated between two additional conductive and transparent thin-film 'stators' that replace the rigid steel stators found in a traditional MartinLogan speaker. Measuring only 20 microns thick, the end result looks like little more than a traditional automotive window tinting material but offers the blinding speed, vanishingly low distortion, and audiophile-grade high-resolution sound reproduction capability of MartinLogan's award-winning home speakers.
At last you can be a car enthusiast without sacrificing great sound!
Joe Vojtko shows off the prototype material called VaporSound™ technology.
Once applied, the speakers are completely transparent and invisible to the human eye.
How It Works
The resulting material works much like our typical electrostatic floorstanding speakers, but without the perforated metal stators. There is a thin-film diaphragm that is "sandwiched" between two acoustically clear stators. A fixed positive voltage is applied to the film and an amplifier provides the constantly changing signal to the stators creating the movement that creates sound.
