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

Key facts

  • sizes: 500x400x90 mm (a 600x500x90 mm version will be announced shortly)
  • weight: 14.5 kg (500×400 mm version)
  • payload range: 0 – 65 kg
  • automatic leveling with a repeatability of 25 µm
  • DC plug with 2.1mm inner diameter pin

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.

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.
