How do they work? What makes them sound so good?

Updated: Mar 20 2018

The curved transparent panel that all MartinLogan ESL speakers use is called an electrostatic transducer. The transducer converts energy from one state into another. The electrical energy from your amplifier is converted into mechanical energy via the motion of the ESL's diaphragm. This causes the air pressure in your listening room to rise and fall exactly as the recorded music does. The sequence of rising and falling air pressure is picked up by your auditory system and interpreted by your brain as sound.

The reason that MartinLogan ESL speaker systems reproduce sound so accurately is the patented electrostatic diaphragm that is driven directly by charged electrons. It is so ultra-thin it weighs less than the air it moves. Such a low mass diaphragm is ultra-responsive... so much so that it reproduces sounds at accuracy levels only associated with the finest audio electronics.

You experience each performance with stunning detail, power, and clarity.

Uncompromising performance. Unflinching accuracy. Unwavering reliability. Harnessing the myriad technical advantages of electrostatic principles to recreate sound in its truest form—this is what MartinLogan is all about.
