Speaker Match

Speaker Match is based on an old idea we tried more than 20 years ago using a Zobel at the speakers built of the best and most expensive components available. This made a big difference to standard parts normally used in commercial versions.

We spent a lot of time researching a universal approach, which is working perfectly in all kind of constellations. 10 years later we improved this very good design, by molding the internal parts into a specially designed casting compound, which was not dampening but stabilizing the total performance.
Zobels are well known as they may have a positive effect on the sound. They may reduce high frequency distortion and intermodulation created by other electrical devices used at home, like energy saving lamps, computers, refrigerators, etc.

The advantages of SteinMusic RCS (Resonance Control System) in Audio Electronics at the example of SteinMusic Speaker Match

All electronic circuit use resistors that generate heat when current is flowing.
This must not be much depending on the topology where it is used and most of the time you will not even remark it, but this is always the fact.
Heat is nothing but the movement of the atoms of a material. In audio circuits these movements are produced by the music signal. Depending on the material properties, dimensions and structure of the surface, these movements create specific material resonances. In reverse, these resonances have an impact on the current flow through the resistor which is nothing else than the musical signal that we want to keep undistorted.

The typical approach is to dampen these resonances. This is not our idea, as experience shows that dampening also draws musical energy that we want to keep, and so often makes a somewhat pleasant but dull sound, where many details and finesse get lost.
Another approach is to stabilize the environment, for example casting the parts into concrete. Here we found that the sound gets stabilized, but is also influenced by the character of the material used. Like in an instrument, you will always find the sonic signature of the material in the sound that is generated. Concrete gives a pretty hard sound, wood, depending on what kind of wood used, a more soft and sometimes pretty pleasant sound. Overall, more natural sounding materials will lead to a more natural sound in the electronics.

For the Speaker Match we use a combination of a special casting compound that is optimized regarding its sonic properties together with a cardboard housing that is soaked with a special resonance optimizing lacquer. The casting compound ensures that all surfaces of the components are completely encased; the treated cardboard provides a good outer surface. The quality of the outer surface is very important, as at this surface, like at a billiard table, all internal resonances are reflected into the material again. The character of the surface always has a big impact onto the overall resonance pattern.
This idea is also the active principle of SteinMusic Maestro lacquer, which has a very positive effect on sound used on nearly all surfaces like speaker diaphragms, tonearms, connector housings, etc. in an audio system.

We already tried Speaker Match with a wooden housing, which was a further step to improve it.
However this is a really big effort, as to work perfectly there needs to be a close contact between all parts inside, and using the special compound is not easy in combination with wood.
The positive effect that you may easily detect: Sound is much clearer, smoother and more detailed using the SteinMusic RCS.
