Goldmund’s goal is to always offer the best, reach unreasonable limits whatever means needed to achieve them, and ultimately deliver an unparalleled sound experience. This is why Goldmund studies and analyzes the weak points of each chain, researches the causes, studies the problem and proposes a solution. Every link in the chain, every device and component, are the result of this wealth of knowledge and know-how.


With the aim of ensuring the sound transparency of our loudspeaker systems, we have implemented a modeling procedure enabling any component, as well as the whole systems themselves, to be under control.

Proteus is a mathematical software based on a huge number of specifications such as loudspeaker system solution, enclosure shape and volume, T&S parameters, driver localisation, diffraction at box edges and more. The modeling enables the loudspeaker system to be calculated in impedance, volume velocity, membrane displacement and sound pressure anywhere in space, in amplitude, phase and group delay.

The calculations of our proprietary digital filtering and Leonardo time correction are included in the Proteus software.

Proteus HOME THEATRE modeling©

The Proteus modeling for home theatre is a Goldmund proprietary software enabling ideal performances in all types of room. It takes into account the geometry of the room and the constraints of construction and decor.

In order to ensure a complete and coherent immersion, the software calculates screen size, listening position and optimized number of drivers, their models, individual locations in the room, and settings in terms of gain, delay and signal mixing. It must be emphasized that the Proteus modeling for loudspeaker systems is included in the Proteus software for home theatre.

This Proteus technology may be applied to an infinity of home theatre solutions comprising in-wall elements only, a mix of in-wall and external elements, external elements only, or even high-end speakers of different brands integrated to a Goldmund system.


In the past, the audio distortions were supposed to rely only on amplitude non-linearities, but recent studies tend to consider the phase non-linearities equally. The phase distortion alters the sound realism, the size and depth of the sound stage, the localisation, the tightness of bass, and other parameters. Working on the transients, this distortion alters also the timbre of the sound source.

The Leonardo correction suppresses most of those sound alterations by realigning digitally the signal frequencies in time. Thanks to this deployment, the listener brain can focus on the sound itself instead of spending energy in the correction process.

Time correction to prevent audio distortion


The Goldmund D/A technology uses a specially designed, unique kind of ultra-linear, time-coherent analogue filtering, achieving a time error of less than 100 picoseconds in the bandwidth. The three major parts of Alize D/A circuit are :

=> A new type of digital interface with quartz locked frequency that cancels all jitter from the signal.

=> Ultra-fast D/A circuitry : Alize topology is undergoing continuous improvements.

=> A new kind of extremely complex analogue filtering (multi-stage) with extreme time alignment providing unique aliveness and exceptional « Recognition Factor ».


As a rule, the more powerful your amplifier, the better control it will have on your speakers. The amplifier controls the speakers in two ways: in giving them enough power to produce a high quality and undistorted sound, but it also controls the drivers better and prevents them to produce sound of themselves. This is especially true for low frequencies when drivers tend to move back and forth, producing unwanted sound that affects the purity of the signal.

With Telos amplification technology, a considerable reduction of the intermodulation has been achieved by improving the linearity of all stages and by considerably decreasing the time distortion. Based on the Goldmund Leonardo research program, the Telos uses a higher bandwidth circuit with minimal group delay distortion inside the audio bandwidth.

Telos amplifier input circuitry now includes the lastest version of Alize Digital/Analog converter circuits. This improves coupling with Goldmund Universal Preamplifiers. Separate input and output stages prevent feedback between high and low current circuits and improve mechanical grounding.

One of the most important sonic improvements provided by the new Telos circuit is its « driver control ». Obtained by lowering the output impedance of the amplifier to an extreme degree, it provides a much higher quality of micro-dynamics and helps large woofers to overshoot resulting in boomy bass. 

Telos amplifies the audio signal with incomparable purity and transparency whatever the volume, without distortion.

Mechanical Grounding Technology Against Audio signal distortion


Introduced by Goldmund in 1982, the “Mechanical Grounding™” building technology uses physics laws to evacuate vibrations from any structure, allowing lower resonance from speakers but also from electronics, where mechanical vibrations are one of the major sources of coloration. As a result, there is no overemphasis on certain tones and the sound preserves its naturalness.
