Oehlbach XXL AIR CYLINDER
Oehlbach sealed air-cushion isolation discs, designed to decouple vibration-sensitive audio equipment from the floor, without relying on a mechanical spring.
Description
The XXL Air Cylinder is an isolation disc designed to decouple audio equipment from the surface on which it rests. It is placed under a hi-fi component considered sensitive to vibrations transmitted by the floor or the furniture, with the aim of limiting their influence on sound reproduction.
The distinctive feature of this model lies in its spring-free design. Isolation relies on a predefined volume of air, sealed between two precisely fitted metal half-cylinders. Two silicone rings ensure an airtight seal between the two chambers thus formed, creating a sealed air cushion that absorbs vibrations without traditional elastic elements. Rubber supports also ensure stable contact with the supporting surface.
This type of accessory is intended for users wishing to optimise the setup of equipment sensitive to mechanical vibrations, such as turntables, players or amplifiers, particularly when these are placed on furniture or a floor liable to transmit resonances.
What to check before buying used
Check that the two silicone rings sealing the half-cylinders are intact, with no cracking or loss of elasticity, as any air leak would cancel out the decoupling effect. Also check that the two metal half-cylinders show no impact damage or deformation that would compromise their fit, and that the rubber supports under the base still adhere well, with no hardening or cracks.
