Four-leg, two-level modular design. Multi-layer shelves finished with natural olive wood veneer (high-gloss). Solid multi-layer legs finished in black piano gloss.
Double shelves are separated using the proprietary BBS (Balancing Board System), combining point-contact support with multi-stage vibration damping.
The structure consists of two independent modules, separated by adjustable anti-vibration spikes, and can be expanded with additional modules.
Images may also present alternative finish options, illustrating available color and material variations.
The QUARTET/BBS extends the modular concept of Rogoz Audio racks towards a wider working surface, allowing multiple components to be placed side by side on each level while maintaining effective isolation.
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.
