Loudspeaker technology company | MartinLogan 20 specification

Inductor.. A device designed primarily to introduce induc- tance into an electrical circuit. Sometimes called a choke or coil.

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.

NAC.. The abbreviation for natural ambience compensation.

Passive crossover.. Uses no active components (transis- tors, ICs, tubes) and needs no power supply (AC, DC, battery) to operate. The crossover in a typical loudspeak- er 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 gener- ation 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 vibra- tion frequency of a body is greatly amplified by reinforcing vibrations at the same or nearly the same frequency 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 converts the energy in form. Loudspeaker transducers convert elec- trical 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 woofers but are more accurately described as being mid/bass drivers.

20 specifications

MartinLogan has long been recognized as a leader in the world of high-end audio, and their speakers, particularly the MartinLogan 20 and 40 models, embody the pinnacle of their innovative approach to sound reproduction. These speakers integrate cutting-edge technology with stunning design, ensuring that audio enthusiasts receive an unparalleled listening experience.

The MartinLogan 20 is a testament to the brand's commitment to electrostatic speaker technology. One of its standout features is the proprietary, high-performance, foldable electrostatic transducer. This design allows for an extremely fast response time and remarkable clarity in sound reproduction, capturing every nuance of the audio. The speaker also boasts a frequency response that extends from 34 Hz to 20 kHz, ensuring rich, deep bass and crystal-clear highs.

On the other hand, the MartinLogan 40 model enhances this experience with additional features geared toward an even wider sound stage. It incorporates a unique Active Bass Control system, which allows users to adjust low-frequency performance to match their room's acoustics. This adaptability is complemented by a dynamic woofer designed to deliver powerful bass without distortion, even at high volumes.

Both models utilize advanced materials, such as the lightweight and rigid aluminum frame construction, which contributes to a more focused and accurate soundstage. Additionally, they feature advanced crossover networks that seamlessly blend the electrostatic and dynamic drivers, ensuring a cohesive sound that immerses the listener.

The aesthetic appeal of MartinLogan speakers cannot be overlooked. The 20 and 40 models feature elegantly curved cabinets with a striking finish that complements any décor. Beyond their beauty, the speakers are engineered for optimal placement in various environments, including home theaters and dedicated listening spaces.

Moreover, the models are equipped with bi-wire capability, allowing audiophiles to use separate cables for the high and low frequencies. This feature enhances the overall performance and offers a level of customization for advanced users.

In conclusion, MartinLogan's 20 and 40 models represent a harmonious fusion of groundbreaking technology and artistic design. With their exceptional sound quality, innovative features, and elegant aesthetics, these speakers are well-suited for discerning audiophiles who demand the best from their audio equipment. Whether for a casual listening session or an immersive cinematic experience, these speakers elevate the auditory journey to new heights.
