Four-leg, three-level modular design. Sandwich-structured shelves finished in piano white gloss.
The structure is based on independent modules that can be arranged vertically (stacked in any order) or placed side by side. Each level functions as a separate mechanical unit, isolated from the others.
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: white gloss.
Images may also present alternative finish options, illustrating available color and material variations.
The 4SM3 MKII is designed as a modular solution for advanced audio systems, offering flexible configuration and enhanced stability of a four-leg structure, resulting in effective vibration control and consistent operating conditions.
Vibration control and mechanical stability
Rogoz Audio racks are designed as systems that control the flow of mechanical energy. In the 4SM3 MKII model, the key elements are modular separation, mass, and point-based support.
Each module is mechanically isolated using adjustable cones and interface elements, limiting vibration transfer between levels and enabling controlled energy dissipation.
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 sandwich-structured shelves promote dissipation and damping of vibrational energy rather than its accumulation.
Point support reduces the contact surface, limiting vibration transfer and enabling controlled energy flow.
Quartz sand ballast increases system inertia and introduces additional internal damping, acting as a mechanical filter for higher-frequency vibrations.
Each rack is delivered with a factory-optimized ballast filling, with further tuning available via adjustable ballast.
Sound performance
In practice, this results in a more natural and stable sound presentation, improved low-frequency control, and greater precision in imaging and instrument separation — particularly in complex multi-component systems.
