Electrostatic Advantages     17

Another significant advantage of MartinLogan’s exclusive 

transducer technology reveals itself when you look at exam-

ples of other loudspeaker products on the market today.  

The Ethos uses no crossover networks above 375 Hz 

because they are not needed. The Ethos consists of a single, 

seamless electrostatic membrane reproducing all frequen-

cies above 375 Hz simultaneously. How is this possible? 

First we must understand that music is not composed 

of separate high, mid and low frequency pieces. In fact, 

music is comprised of a single complex waveform with all 

frequencies interacting simultaneously. 

The electrostatic transducer of the Ethos essentially acts 

as an exact opposite of the microphones used to record 

the original event. A microphone, which is a single work-

ing element, transforms acoustic energy into an electrical 

signal that can be amplified or preserved by some type 

of storage media. The Ethos’s electrostatic transducer 

transforms electrical energy from your amplifier back into 

acoustical energy.

Due to the limitations of electromagnetic drivers, no single 

unit can reproduce the full range of frequencies. Instead, 

these drivers must be designed to operate within a nar-

row, fixed bandwidth of the frequency range, and then 

combined electrically so that the sum of the parts equals 

the total signal. While nice in theory, we must deal with 

real-world conditions.

In order to use multiple drivers, a crossover network 

is enlisted to attempt a division of the complex musical 

signal into the separate pieces (usually highs, mids, and 

lows) that each specific driver was designed to handle. 

Unfortunately, due to the phase relationships that occur 

within all crossover networks and during the acoustical 

recombination process, nonlinearities and severe deg-

radation of the music signal take place in the ear’s most 

critical zone (see figure 14).

The Ethos’s electrostatic transducer can single-handedly 

reproduce all frequencies above 375 Hz simultaneously. 

You have in one transducer the ability to handle in ele-

gant simplicity the critical frequencies above 375 Hz.

The crossover phase aberrations that are associated with 

traditional tweeter, midrange, and woofer systems are 

eliminated. The result is a dramatic improvement in imag-

ing and staging performance due to the minutely accurate 

phase relationship of the full-range panel wave launch.

speaker system must use multiple crossover networks 
that have negative effects on the musical performance.
