WARNING!

 Do not use your Ethos loudspeakers outside of the country of original sale—voltage requirements 

vary by country. Improper voltage can cause damage that will be potentially expensive to repair. The Ethos is 

shipped to authorized MartinLogan distributors with the correct power supply for use in the country of intended 

sale. A list of authorized distributors can be accessed at www.martinlogan.com or by emailing [email protected]

Linearity .

 

The extent to which any signal handling process 

is accomplished without amplitude distortion. 

 

Midrange .

 

The middle frequencies where the ear is the 

most sensitive. 

 

Passive .crossover .

 

Uses no active components (transistors, 

IC’s, tubes) and needs no power supply (AC, DC, battery) 

to operate. The crossover in a typical loudspeaker is of the 

passive variety. Passive crossovers consist of capacitors, 

inductors and resistors. 

Phase .

 

The amount by which one sine wave leads or lags 

a second wave of the same frequency. The difference is 

described by the term phase angle. Sine waves in phase 

reinforce each other; those out of phase cancel. 

Pink .noise .

 

A random noise used in measurements, as it 

has the same amount of energy in each octave. 

Polarity .

 

The condition of being positive or negative with 

respect to some reference point or object.

RMS .

 

Abbreviation for root mean square. The effective 

value of a given waveform is its RMS value. Acoustic 

power is proportional to the square of the RMS sound 

pressure. 

Resistance .

 

That property of a conductor by which it 

opposes the flow of electric current, resulting in the 

generation of heat in the conducting material, usually 

expressed in ohms.

Resistor .

 

A device used in a circuit to provide resistance.

Resonance .

 

The  effect  produced  when  the  natural 

vibration frequency of a body is greatly amplified by 

reinforcing vibrations at the same or nearly the same fre-

quency from another body. 

Sensitivity .

 The 

volume of sound delivered for a given 

electrical input. 

Stator .

 

The fixed part forming the reference for the moving 

diaphragm in a planar speaker. 

THD .

 The 

abbreviation for total harmonic distortion. (See 

Distortion)

TIM .

 The 

abbreviation for transient intermodulation distortion. 

Transducer .

 

Any of various devices that transmit energy 

from one system to another, sometimes one that con-

verts the energy in form. Loudspeaker transducers convert 

electrical energy into mechanical motion. 

Transient .

 

Applies to that which lasts or stays but a short 

time. A change from one steady-state condition to another.

Tweeter .

 

A small drive unit designed to reproduce only

high frequencies. 

Wavelength .

 

The distance measured in the direction of 

progression of a wave, from any given point characterized 

by the same phase.

White .noise .

 

A random noise used in measurements, as it 

has the same amount of energy at each frequency. 

Woofer .

 

A drive unit operating in the bass frequencies 

only. Drive units in two-way systems are not true woof-

ers but are more accurately described as being mid/bass 

drivers.
