Seismion presents the all-new Reactio 2!
Seismion is thrilled to annouce the all-new Reactio 2 active vibration isolator. It is the consequent advancement from the original Reactio and the Reactio plus. The Seismion Reactio 2 is a professional tool for perfect vibration isolation without compromises. It was developed with the toughest criteria both from the high-end audio field as well as industrial use in metrology and semiconductor production. It features an exceptional isolation performance starting in the sub-Hertz range, in a totally new housing.
It features the following key specifications and improvements compared to our already highly successful Reactio plus:
- more than -10 dB reduction already at 1 Hz
only a very exclusive circle of active vibration isolators is capable of such a performance. It efficiently isolates even building vibrations and reaches more than -20 dB around 5 Hz, where the disturbances are typically the highest
- fully automatic leveling functionality
the Reactio 2 includes several deflection sensors and motors. By automatic leveling it is assured that the top-plate is always perfectly aligned with a repeatability of 25 µm. By that, the sensors and actuators always operate under optimal conditions
- locking functionality
with a push on the button, the top-plate can be locked against the housing. By that also the passive isolation is eliminated, and delicate equipment like turntables can be setup
- differential measurement technology
the vibration sensors of our Reactio isolators are designed with the differential measurement technology. By that, their susceptibility to interferences is greatly reduced compared to single-ended technology, which is the standard in industry
- 2x better noise performance than the former Reactio plus
the total noise generation is simulated by sophistical computer models, and with a selected choice of Operational Amplifiers the noise floor could be reduced even further. Ther result is a perfectly clean and silent background
- higher passive resonance damping of top- and bottom-plates
for additional passive damping especially at higher frequencies, the top- and bottom-plates are now made of MDF fiberboards
- design optimized for high-end audio usage
high-quality push button, DC-connector and housing, all our isolators are hand-finished in our production site in Hannover, Germany. We only use highest quality components and a perfect finish
- optional colour schemes available
on request the Reactio 2 can be ordered in different colour schemes like black or pure gold

Active vibration isolation and stabilization
Audiophiles strive for the perfect rendition of music recordings. Vibrations are sound, and sound is vibrations. This becomes particularly evident with the sound pickup of turntables. It is no longer possible to distinguish between parasitic vibrations and music information stored in the grooves. Also many other components like tubes are microphonic, which means that vibrations have an impact upon the output signal.
Therefore, all disturbing influences in the whole chain need to be eliminated. Seismion Reactio 2 brings you closer to that goal than ever before (the advantage of active isolation). Originally developed to meet the highest standards for applications like semiconductor inspection, nanotechnology and industrial metrology, it is now also available for the high-end audio field.
Being an active system, it features extremely sensitive piezoelectric sensors, which detect even the smallest vibrations. An all-analog electronic control circuit generates the required compensation forces. It was possible to minimize distortions and noise floor down to one half compared to the former Reactio plus.
Inspired by Newton’s third law of motion, Seismion Reactio 2 produces exactly the required counter forces to stop any vibration, coming from the base or being generated in the unit itself (more about the difference between isolation and stabilization),
The result is simply pure music like one has hardly experienced before.
Seismion Reactio 2 features a totally new design with a single push-button with LED indication. The top- and bottom plates are made of MDF to provide further passive damping in the high frequency range.
The Reactio’s are working perfectly and the sound is further enhanced. Very nice sound indeed.
Seismion is notably better than the other brands of isolators. The sound is cleaner, image is sharper and music flows more naturally. It has never been this good.
I see a great potential of Seismion isolators in audio market.

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 2 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).
Active damping base ADB01 designed by Helmut Thiele
Helmut Thiele, world-wide acknowledged by his own turntables and tonearms, teamed up with Seismion for designing a new active damping base. While the design came from Helmut Thiele, Seismion contributed with its well-proven active isolation technology known from our Reactio. A first review can be found at HIFIStatement (only in german language), and a first sample will be showcased at this year’s AXPONA in Chicago.
