Four-leg, four-level design. Sandwich-structured shelves (40 mm) finished in high-quality lacquer (gloss or satin depending on configuration).
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.
Images may also present alternative finish options, illustrating available color and material variations.
The 4SB4 MKII is designed as a reference-grade rack for demanding audio systems, offering four independent levels, very high load capacity, and maximum structural stability.
Vibration control and mechanical stability
Rogoz Audio racks are designed as systems that control the flow of mechanical energy. In the 4SB4 MKII 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 structural elements made of high-strength S355 alloy steel.
The thick (40 mm) sandwich-structured shelves promote dissipation and damping of vibrational energy rather than its accumulation.
Each level is supported by adjustable anti-vibration spikes, reducing contact surface 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 enhanced clarity and separation — particularly in complex multi-component systems.
