Offered is „Reactio Plus“ by Seismion as exhibit from the category „Furniture, Stands, Spikes, Acoustical Elements...“ on audio-markt.de - the online market place for high-end. The advert with the number 9841294697 ends on 16.10.2026 at 06:37 o'clock.
This is a buyer’s market for the category at the moment: at €5,900, the asking price sits below the €6,368 25th percentile and well under the €6,896 median, so it reads as a strong deal rather than a merely fair one.
That makes it interesting for anyone who wants a well-regarded piece without paying top-of-market money. A clean used example at this level is the kind of listing that can make sense quickly if the unit is complete and functioning properly; the main upside is simply getting into a respected product at a discount. I’d move fastest if it includes the original packaging, controller, and any calibration or setup extras.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Seismion emerged from Germany’s precision engineering heritage during the COVID-19 pandemic, when Dr. Neubauer, a vibration isolation expert, partnered with electrical engineer Sebastian Mojrzisch to adapt industrial technology for audiophile applications. Based in Hannover, the brand quickly transitioned from supplying Chinese industrial clients to targeting high-end audio enthusiasts, leveraging decades of mechatronic expertise in active vibration control.
The company specializes in advanced vibration isolation solutions, including active platforms like the Reactio 51, audio racks, and experimental loudspeaker isolators. These mechatronic systems employ sensors and actuators to neutralize micro-vibrations, enhancing clarity across turntables, amplifiers, speakers, and full hi-fi setups. Far from conventional spikes or feet, Seismion’s products represent a technological leap in isolating components from environmental noise.
Positioned as a niche boutique leader in the high-end market, Seismion garners acclaim for game-changing performance, with reviewers hailing it as a reference standard that redefines isolation. Showcased at events like High-End Munich and Axpona, and backed by North American distribution through MIBS, it appeals to discerning buyers seeking measurable sonic upgrades in premium systems.
