Four-leg, two-level modular design. Multi-layer shelves finished in natural olive wood veneer with a high-gloss finish. Solid, multi-layer legs finished in high-gloss black piano lacquer.
The vertical fluting of the legs is not merely a styling detail, but a deliberately shaped sound-scattering surface. The pattern of grooves and edges is designed to disperse early reflected energy across the horizontal plane – particularly in the midrange – reducing the directional concentration typical of a broad, smooth surface. This is especially relevant when the rack is positioned between the loudspeakers or in their immediate vicinity.
The dual-layer shelves are decoupled using the proprietary BBS (Balancing Board System), which combines point-contact support with multi-stage vibration damping.
The rack comprises two independent modules, isolated from one another by adjustable anti-vibration spikes. Additional modules can be added as required.
Product images may also show alternative finishes, illustrating the available color and material options.
The QUARTET/BBS extends Rogoz Audio’s modular rack concept with a wider usable surface, allowing multiple components to be positioned side by side on a single level while maintaining effective isolation between them.
Vibration control and BBS system
The BBS system is based on a set of precisely interacting elements: a height-adjustable steel cone, an intermediate carbon polymer element, and steel sockets embedded in the shelves.
Point contact stabilizes the structure while allowing controlled pendular motion, followed by limited rolling and sliding movement at subsequent contact points.
This sequence prevents linear transmission of vibration energy and enables its gradual dissipation through friction, rolling resistance, and internal damping.
The system combines minimal contact area with effective damping of transverse and oblique vibrations.
The BBS system is protected by patent UPRP P.404137.
Sound performance
In practice, this results in a stable, dense and well-organized sound presentation with strong low-frequency control and high clarity — particularly in complex multi-component systems.
