M3X

About the M3X

The HRS M3X Isolation Base is a flagship product from Harmonic Resolution Systems, engineered to minimize the negative impact of structure-borne vibration on audio and video components. It is constructed from over 70 parts using six different materials, including proprietary polymers, billet machined aircraft aluminum, and polished black granite. The design optimizes stiffness, mass, energy dissipation, and mechanical impedance to enhance audio clarity, definition, and resolution. The M3X features a low-profile, heavy, and extremely solid build that fits most equipment racks without bowing under weight. It includes interchangeable feet options (Broadband Isolation Feet, Low Frequency Feet, Bi-Directional Noise Reduction Feet) to tailor performance to specific components. The base improves tonal balance by adding energy in the lower midrange, resulting in a more powerful yet well-defined soundstage. It is compatible with HRS damping plates and Nimbus products for further vibration control and is available in standard and custom sizes to fit any audio component.
