Seismion Reactio is a high-performance vibration isolator (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

with as little distortions as possible. Inspired by Newton´s third law of motion, Seismion Reactio 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.

A great installation by eliminating both footfall vibration and speakers feedback through the . The black backgrounds and ability to allow micro details through is the icing on the cake. Active vibration with the Reactio 651.

First good look Reactio 2.0. It has twice the isolation capability of the Plus version. Automatic leveling at turn on, high quality linear power supply built in to a figure 8 power connection with separate ground , and load capacity to 60 kg. Shown here in the 400x500 configuration the 600x500 will follow shortly the followed by an ever higher load capable unit. Stay tuned for more information.
