Four-leg, three-level design. Sandwich-structured shelves finished in piano black gloss.
The top shelf is optimized for turntables and high-end digital source components.
The frame is designed for quartz sand filling — threaded openings located at the rear of the legs allow adjustment of both the amount and type of ballast. Frame finish: black gloss.
Images may also present alternative finish options, illustrating available color and material variations.
The 4SPB3N MKII is designed for advanced audio systems where stable and precise support for source components is essential, offering a multi-level, high-capacity structure with an optimized top-shelf geometry.
Vibration control and mechanical stability
Rogoz Audio racks are designed as systems that control the flow of mechanical energy. In the 4SPB3N MKII model, the key elements are mass, structural rigidity, and point-based support.
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) feature varied density and internal structure, promoting dissipation and damping of vibrational energy rather than its accumulation.
Point support on adjustable anti-vibration cones reduces the contact surface, limiting vibration transfer and enabling controlled energy dissipation.
Filling the legs with quartz sand increases system inertia and introduces additional internal damping. The granular material acts as a mechanical filter, effectively dispersing higher-frequency vibrations and limiting their propagation within the structure.
Each rack is delivered with a factory-optimized ballast filling, ensuring proper operating conditions. At the same time, the design allows for further tuning — threaded openings in the legs enable adjustment of the amount or type of ballast, allowing users to fine-tune performance.
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 important in multi-component systems.
