Electrostatic speakers: A very different way to make sound
MartinLogan's new ElectroMotion Series of speakers feature electrostatic and other technologies to produce extraordinary sound quality.
Just about every speaker you've ever heard uses cone woofers and dome tweeters that feature a coil of wire in a magnetic field that pushes the diaphragm back and forth to make sound. Lots of great audiophile-grade speakers use conventional drivers of this type.
Flat electrostatic panel speakers work on a completely different design principle. These speakers use a superthin, but large, surface area diaphragm, coated with a conductive material sandwiched between two electrically conductive grids.
Electrostatic speakers produce levels of distortion one to two orders of magnitude lower than conventional cone drivers in a box. Electrostatic speakers' clarity is extraordinary. The big downside is high cost, but electrostatic speakers have been popular with audiophiles for many years.
MartinLogan is America's best-known manufacturer of electrostatic speakers. I've heard previous generations of the company's speakers many times, and was consistently impressed by their sound. Its all-new ElectroMotion series of speakers will feature electrostatic and MartinLogan's proprietary Folded Motion drivers.
The floor-standing ElectroMotion ESL speaker is one of the most affordable full-size electrostatic designs ever offered by the company. Voice-matched center and surround speakers will also be available.
The EM-ESL features a full-size 34-inch tall curved XStat electrostatic transducer, housed within an aluminum and composite AirFrame similar to those found on MartinLogan's flagship products. The EM-ESL also features an 8-inch audiophile grade woofer, custom designed by MartinLogan.
Priced at $1,995 per pair, the ElectroMotion ESL is scheduled to ship this month and will be available at high-performance audio retailers worldwide. Matching center- and surround-channel speakers featuring Folded Motion XT technology will debut shortly thereafter.
