Maxxum-Ultra
Critical Mass Systems’ advanced reference equipment rack: a custom-built vibration-control platform using technology derived from the flagship OLYMPUS-ULTRA. Its dual-zone, 12-stage damping system addresses vibration throughout the floor, rack, shelf and supported component.
Key Features
- Patented dual-zone, 12-stage vibration-damping architecture
- Technology derived from the flagship OLYMPUS-ULTRA
- Integrated rack-and-filter design engineered to control vibration throughout the complete support structure
- Upper and lower six-stage damping zones
- Each damping zone incorporates a 21-layer constrained sandwich
- Six damping materials precisely sequenced using nomograph damping data
- Three different upper-plate materials selected for rigidity under load
- Aluminium-alloy shelf framework
- Precision construction with horizontal and vertical tolerances of 0.0005 inches
- Titanium-alloy X-axis lockdown bolts
- Fully adjustable levelling
- Approximately 200 lb / 91 kg capacity per component, with higher-capacity configurations available
- Custom-made for amplifiers, vertical racks and side-by-side component systems
Design & Build
The MAXXUM-ULTRA applies Critical Mass Systems’ thermodynamic approach to vibration management through a rack and shelf system engineered to function as a unified structure. Rather than treating the equipment shelf as an isolated accessory, its architecture addresses vibration originating in the floor, rack, shelf and audio component simultaneously.
Each exclusive MAXXUM-ULTRA shelf employs an aluminium-alloy framework and two independent six-stage damping zones. The upper and lower zones each contain a 21-layer constrained sandwich, with multiple structural and damping materials arranged to provide rigidity while controlling unwanted mechanical energy.
System Pairing
Originally engineered around the demanding isolation requirements of turntables, the MAXXUM-ULTRA is equally suited to digital sources, preamplifiers, power amplifiers and power-conditioning components.
Its made-to-order architecture accommodates individual amplifier platforms, conventional vertical equipment racks and wider side-by-side systems. Custom vertical spacing and optional higher load capacities allow each installation to be configured around the owner’s equipment.
