Audiophile excellence

Music moves us – as engineers, as musicians and as people. For 40 years, we at Mundorf have dedicated ourselves to the inner quality of sound – to the components that work behind the scenes yet make all the difference. Our components protect music from distortion and give it depth, structure and expression. They create the foundation for moving musical experiences. “Inner Excellence” is our contribution - and “True Music” the result.

With passion and precision, we develop premium components and solutions used worldwide in loudspeakers, amplifiers and other audio equipment – helping create an authentic and deeply engaging listening experience.

Inner Excellence – wherever sound is created.

What began with coils has grown into a complete portfolio of premium components for almost every audio application. Whether in the studio, on stage, in the car or at home – wherever music comes to life, our capacitors, inductors, AMT tweeters, resistors, wires and other products contribute to an engaging listening experience.

Macro-Microphony

In wound components, electromagnetic forces create mechanical vibrations. This costs energy and overlays the signal with distortion and noise – detail and spatiality are lost. Through purposeful design we eliminate these effects and preserve dynamics, precision and sonic purity.

Micro-Microphony

Microscopic effects within the material, such as lattice vibrations and electron scattering, subtly affect the signal. They cannot be avoided entirely – but they can be controlled. Using special alloys and tightly controlled processes, we optimize the resonance behavior for maximum signal purity.

Electrical Parameters

Capacitance, inductance and losses determine behavior – but they are not constant. They vary with frequency, temperature and voltage, shaping the sound. That is why we develop and test across all relevant ranges to ensure stability, low losses and musical balance.

SINCE 1985

From the living room to the Royal Albert Hall

Before the first coil was wound in 1985, the foundation had long been laid – in a childhood full of music, curiosity and enthusiasm for technology. From these beginnings grew a company that developed into an internationally respected reference brand for high-end audio components – with Mundorf components now found in some of the world’s most renowned loudspeaker systems and amplifiers.

Foundation
Foundation

1985

  • Start of in-house production: perfecting the coil
  • Air coils of round and flat wire from 0.12 to 12 mm²
  • FERON transformer core coils, load capacity > 1 kW; highly permeable core sheet for taut bass
  • The Zero-Ohm coil: extremely low RDC enables controlled, taut bass, otherwise only achievable in active operation.
  • Resin soaking: the first successful application of the macro/micro-microphony theorem
  • Aronit beats ferrite, a new core material. High load capacity with very low hysteresis distortion, ideal wherever quiet passages matter.
Breakthrough with the Mundorf MCap capacitors
Breakthrough with M-Cap Capacitors

1990s

  • International breakthrough with high-grade capacitors: M-Cap, M-Cap Supreme and M-Cap Supreme Silver-Oil
  • Production of customer-specific crossovers
  • Supplier for high-grade car hi-fi: HeadCap, PowerCap 0.5 to 1.5 F; series-regulated power supplies 13.8 V up to 400 A

Entry into AMT Tweeter Technology
Entry into AMT Tweeter Technology

2000s

  • M-CAP Supreme Silver-Gold-Oil becomes a worldwide bestseller; Mundorf becomes a partner to the industry
  • Holographic Sound Devices: entry into the patented AMT tweeter technology, AMT 2330/40, AMT 2530, AMT 2930
  • First Pro AMT: AMT U56, AMT 576 (diaphragm 576×27 mm)
Mundorf as an all-round partner for loudspeaker building
Established as a comprehensive partner to the audio industry

2010er Jahre

  • Portfolio extended to the full 360° reproduction chain: new M-Cap EVO capacitors, precision resistors, terminals, cables and wires
  • AMT tweeter technology in use worldwide: home, cinema, car and pro audio, from the club to the live event, among them the Royal Albert Hall in London. Extremely demanding service: acoustic instruments and whole orchestras have to be amplified without distortion, tonally neutral and unobtrusively despite considerable levels.
  • Present along the whole chain of reproduction: in the studio and at home, in the car and on stage, source → electronics/crossovers → loudspeakers. Mundorf AMT tweeters and precision components accompany every stage.
