Isolating all vibrations above 1 Hz
Isolation is absolutely crucial for high-end audio systems. Even the slightest vibration from ambient sources is affecting the sound reproduction. Transistors, tube amplifiers and also speakers are components especially sensitive to vibration excitation.
As most vibrations are reaching the equipment through the floor, the critical frequency range is typically in the range from 2 to 10 Hz. This is where the active Reactio is performing especially well.
Extremely low noise floor due to selected electronics
It is a fact that all active systems generate some self-noise. Even piezoelectric sensors include to a certain amount noise in the sensor signal. The sensor signal is amplified multiple times in the feedback loop to generate the compensation forces. As the control cannot distinguish between the noise and the real signal, also the noise reaches the actuators and excites the isolated platform with a certain noisy vibration spectrum. This is a common concern amoung audiphiles, as even the slightest noise disturbs the music reproduction.
However, realizing the lowest noise level amoung all currently available active isolators has been the goal during development. The result is a stunning, low-noise vibration isolation. The difference is audible!
The ultimate challenge for any vibration isolator is to prove its performance under very low vibration excitation. Since a low excitation yields a bad signal-to-noise ratio (SNR), most isolators are not capable to achieve the isolation reduction that is given in their data sheets. Typically, the manufacturers test their isolators with a controlled excitation spectrum by placing the isolator on a shaker table, and choosing a proper vibration level.
These results are rather meaningless for audiophiles, since they would not place their high-end equipment on a place with high vibration excitation.
Seismion, in contrast, measures the performance of its isolators by pure ambient excitations in laboratory (how Seismion measures the performance of its isolators). The vibration level is comparable to what the end-used might experience in their music rooms. Even with this low vibration excitation, the Reactio still offers its full isolation performance.
As a result, Seismion Reactio exceeds even the toughest VC criteria for the most demanding industrial systems in nanometer scale (more on VC curves).
