Rogoz Audio 4SPB3/BBS audio rack


Janusz Rogoż of Rogoz Audi just shared info about their 4-level, four-legged stand with glossy piano finish shelves (natural sappele mahogany veneer; dyed wood: No. 25-25) The frame contains quartz sand ballast (bolted holes in the legs make it possible to change the amount and kind of ballast). The frame color: satin black. The top shelf is 50 mm thick with sandwich structure and is optimal for analog gramophones and digital signal sources. The middle and bottom shelves are 40 mm thick and have a similar structure. All the shelves are separated from the stand frame by the Balancing Board System. BBS has kinematic and dynamic qualities which enable isolated masses to “float” to the sides relative to the system axis, maintaining point support at the same time. BBS also makes it possible to level the stand shelves.

Anti-vibration stands are designed for high end audio components. The frame has been tuned by a suitable combination of alloy steel and high-fiber content steel. The frame consist of extra-strong legs made of carbon steel S235JR (which is used for load-bearing stuctures subject to heavy dynamic load, e.g. in cranes) connected by crosspieces made from higher-strength alloy steel S355. Adjustable anti-vibration spikes are used for for high-precision leveling.

The Balancing Board System

The audio stand structure incorporates a new proprietary Rogoz Audio antivibration system, BBS (Balancing Board System, Patent P.404137 Pending). The system consists of a threaded, height-adjustable spike made of high-fiber-content steel alloy, on top of which two elements are placed, each with an inner bearing. An intermediary (middle) element is made of carbon fiber and supports another element, a steel bearing inserted into the shelf. Point contact between the steel spike and the carbon intermediary element prevents movement of either element relative to its axis, but it allows pendular motion. Meanwhile, the contact between the intermediary element and the bearing inserted into the shelf allows restricted rolling motion and sliding motion. Consequently, the advantages of spike point support (contact area has been minimized and kinetic energy turns into heat) have been combined with the effects of deadening vibrations owing to to sliding friction and rolling resistance.
