The Harmonic Resolution Systems EXR is a modular high-performance audio stand designed to provide effective vibration control, exceptional structural rigidity and extensive configuration flexibility. Manufactured in the USA, its patented asymmetrical four-leg architecture increases frame stiffness, while precision-machined aluminium supports incorporate an internal energy dissipation system to reduce the transmission of unwanted mechanical energy.
Each low-profile plinth combines machined aluminium trim, proprietary HRS constrained-layer damping and resin-fabric composite panels to provide a stable, damped platform for audio components. Unlike other HRS rack systems, the EXR can support equipment directly without requiring additional isolation bases, although HRS E1X, R3X, S3 and M3X2 platforms can be incorporated at any shelf position. Its modular construction accommodates a wide range of component sizes and configurations, with the ability to expand or upgrade the system as requirements evolve.
