Speaker Match Plus

Speaker Match are based on an old idea we tried already more than 20 years ago using a Zobel at the speakers built out of the best and most expensive components available. This already made a big difference to standard parts normally used in commercial versions. We spent a lot of time to find a universal approach, which is working perfect in all kind of constellations, and although I did not expect to be successful with this task indeed we found one. 10 years later we could improve this already very good design further, just by molding the internal parts into a specially designed casting compound, which was not dampening but stabilizing the total performance in a big amount. 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 using resistors will generate heat when current is flowing. This must not be much depending on the topology where it is used in, 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 will have an impact onto the current flow through the resistor which is nothing else than the musical signal that we want to keep undistorted. The typical approach here is to dampen these resonances. This absolutely 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 at 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 also 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. So the character of the surface always has a big impact onto the overall resonance pattern. This idea by the way 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. How this special resonance controlling system in fact works you may easily monitor comparing the series version against the second sample I sent you: the only difference is that the later ones do not have the special compound used. We already tried Speaker Match with a wooden housing, which was a further step to the better. 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.
