Four-leg, three-level design. Sandwich-structured shelves (30 mm) finished with natural wood veneer (American walnut).
The frame is designed for quartz sand filling — threaded openings at the rear of the legs allow adjustment of both the amount and type of ballast. Frame finish: glossy golden brass.
Images may also present alternative finish options, illustrating available color and material variations.
The 4QG3 combines a stable four-leg architecture with a distinctive visual character, offering three independent levels for advanced audio systems.
Vibration control and mechanical stability
Rogoz Audio racks are designed as systems that control the flow of mechanical energy. In the 4QG3 model, the key elements are mass, rigidity, and multi-level isolation.
The structure is tuned through the deliberate combination of different steel types. The frame consists of thick-walled legs made of S235JR carbon steel and crossbars made of high-strength S355 alloy steel.
The sandwich-structured shelves (MDF/HDF/MDF) promote dissipation and damping of vibrational energy rather than its accumulation.
Each level is supported by adjustable anti-vibration spikes, reducing contact area and limiting vibration transfer between levels and from the floor.
Quartz sand ballast increases system inertia and introduces internal damping, acting as a mechanical filter for higher-frequency vibrations.
Each rack is delivered with a factory-optimized ballast filling, with the option for further tuning if required.
Sound performance
In practice, this results in a more stable and controlled sound presentation, improved low-frequency performance, and greater precision in imaging and separation — especially in multi-component systems.
