Cold Ray Fractal
Cold Ray Fractal 7 decoupling foot, designed to limit the effects of secondary vibrations on audio equipment thanks to its fractal shape.
Description
The Cold Ray Fractal 7 is a decoupling accessory intended for sound reproduction systems. It is placed under an audio device (speaker, electronic component) in order to limit the effects of secondary vibrations that propagate from the casing or internal components towards the surface of the furniture or support.
The operating principle relies on a fractal-shaped cross-section. This geometry allows the device to concentrate and then neutralise part of the captured vibrations, while the unabsorbed fraction is dispersed by the fractal shape itself, which reduces its impact on the diffuse sound field. The Fractal 7 is designed with sufficient weight and contact surface to fulfil this function, without itself becoming a source of secondary radiation.
This type of decoupler is aimed at users wishing to refine the acoustic behaviour of their existing installation, particularly when the electronic components or speakers are of a high quality level and casing vibrations become perceptible in the sound output. It concerns configurations where the aim is to address the unwanted effects of the diffuse sound field rather than to modify the device itself.
What to check before buying used
The contact surface must remain perfectly flat: an impact or rough handling can warp it and impair coupling with the furniture or the device placed on it. Examine the edges of the fractal profile, which are particularly exposed to chips and micro-cracks from repeated handling. If the item is part of a set, check that the weight and finish remain consistent from one piece to another, as mismatched units would alter the decoupling balance.
