Four-leg, two-level design. Sandwich-structured shelves (30 mm) finished in piano black gloss.
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: black gloss.
Images may also present alternative finish options, illustrating available color and material variations.
The 4QB2 MKII is one of the most versatile designs in the Rogoz Audio lineup, offering a wide usable surface, high load capacity, and a stable four-leg structure suitable for multi-component systems.
Vibration control and mechanical stability
Rogoz Audio racks are designed as systems that control the flow of mechanical energy. In the 4QB2 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 spikes reduces the contact surface, limiting vibration transfer and enabling controlled energy dissipation.
Quartz sand ballast 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, with the option for further tuning if required.
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 — even in multi-component systems.
