The klangliche meaning of loudspeaker cables,
- Myth or reality?
From practice we know that loudspeaker cables can have a partial drastic influence on the sound quality. That stands in glaring contrast to statements from authorities that a simple 2x1,5 has qmm PVC isolated cable already no klanglichen effects. So far no conclusive instrumentation analysis stood for the subjective impressions to the side.
After 2-jährigen research succeeded in SONICS now with the help of the measuring system Praxis2 von Liberty of instrument proving clear differences instrumentation. In addition we used two methods:
1. At the entrance of the cable a logarithmic sine (Chirp) is fed and the transfer function (frequency response and phase) is taken up. Amplifiers and loudspeakers are attached thereby their exit and feed impedances into the measurement are also received. The same measurement is accomplished at the end of the cable. Now both measurements divided around the influence of the cable to isolating.

From the diagrams (fig. 1) one can recognize clearly the tonal balance. The best result supplies the first cable from above. It is down inductive and low impedance. The Lautstärkeschwankungen remain under 0,05dB. The lowest cable is a 2x1,5 used as comparison qmm cables with PVC isolation. It shows a higher loss and under inductance a high clay/tone waste. The cable sounds dully/mustily, undynamisch and careless.

2. At the entrance music is fed and noted. The same recording is accomplished at the end of the cable. Subsequently, during a mathematical process entrance and exit are taken off from each other. The result corresponds in the cable lost gone information and can be heard and analyzed. The incorrect signal in the lower cable corresponds to 0.8%. The upper cable (2x1,5 qmm PVC) loses 3.7% of the information. That is not insignificant after our view.
For the internal wiring of our loudspeakers we use an down-inductive and low impedance cable, which does not load the amplifier by the good PL isolation improperly. The structure consists core with a diameter of 0,4mm of 4x4 parallel running strands solvently. Thus one prevents to the skin effect and one continues to lower inductance.
Still further subtle effects in cables exist such as Mikrophonie and noise modulation, which we did not describe here for the sake of the clarity. They can be however safe that its SONICS interior wiring is sufficient for highest requirements. We advise against urgently a modification. The warranty could not be carried out otherwise under these circumstances.
