The Harmonic Resolution Systems R3X is a high-performance isolation base designed to control unwanted mechanical vibration and improve the performance of sensitive audio components. Designed and manufactured in the USA, its five-material construction incorporates a CNC-machined non-resonant core with strategically positioned, internally decoupled high-mass damping systems. Custom-pressed resin-fabric composite panels and precision-machined, heat-treated aluminium perimeter trim provide additional structural rigidity and resonance control.
Derived from technologies developed for the HRS S3 and M3X2 platforms, the R3X incorporates interchangeable isolation feet selected to suit the weight and operating characteristics of individual components. Broadband SF, low-frequency LF and G7 bi-directional noise reduction feet allow the platform to be configured for different applications, including turntables, amplifiers, digital sources and power supplies. Available in two standard sizes, the R3X can be used independently on existing furniture or integrated directly into compatible HRS audio stands.
Key Features
High-performance component isolation platform
Designed and manufactured in the USA
Five-material construction with proprietary resonance-control technology
CNC-machined non-resonant core
Internally decoupled high-mass damping systems for energy dissipation
Custom-pressed HRS resin-fabric composite top and bottom panels
Precision-machined, heat-treated aluminium perimeter trim
Scratch-resistant upper surface
Low-profile construction, 76mm (3 inches) high
Derived from HRS S3 isolation platform technology
Same isolation footer technology used in the reference M3X2
28% greater plinth mass density than the previous R1 design
Interchangeable HRS isolation feet, configured for individual components
SF Broadband Isolation Feet: isolation from below 20Hz to above 40kHz
LF Low Frequency Isolation Feet: isolation from below 10Hz to above 40kHz
G7 Bi-Directional Noise Reduction Feet: energy transfer and dissipation
SF isolation feet available in five weight-dependent load ranges
G7 feet do not require weight-specific load matching
Isolation configuration can be changed for future equipment upgrades
Suitable for turntables, amplifiers, DACs, phono stages and power supplies
Can be used independently on existing furniture
Integrates directly into HRS audio stands without modification
Available in black or silver
Two standard platform sizes:
483 × 432 × 76mm (19 × 17 × 3 inches)
533 × 483 × 76mm (21 × 19 × 3 inches)
Platform weight: approximately 11.6kg or 14.1kg, depending on size
Configuration note: Each R3X is supplied with a selected HRS footer configuration. SF and LF feet provide mechanical isolation, while G7 feet provide bi-directional energy transfer and dissipation. The appropriate footer type and load range should be chosen according to the supported component.
