The M3X2 Isolation Base is the latest generation of reference level Isolation Bases from Harmonic Resolution Systems. It results from more than a decade of research and development to achieve true reference-level audio system performance. The M3X2 is manufactured from 70+ parts and six different materials, including two proprietary polymers, billet machined aircraft aluminum housing and polished black granite.
This unique design utilizes six different materials to optimize stiffness, geometry, mass, energy dissipation, and mechanical impedance characteristics. Each material is carefully selected for optimum performance and functionality. The M3X2 Isolation Base also uses four different proprietary HRS materials. The first two are located inside the frame to prevent and eliminate internal noise. The third and fourth proprietary materials are used externally in the footer of the base to optimize performance for different component types or environments.
A finely polished black granite contact plate is combined with the two custom resonance control stages inside the billet machined aircraft aluminum frame. The external visual surfaces of the frame have a craftsmanship finish and special HRS black anodize coating. This exceptional design was created to offer maximum performance, cosmetic elegance, and a very durable scratch-resistant inlay design that will provide years of maintenance-free service. The low profile (3-inch high) design also minimizes space requirements and keeps the visual focus of your system on the components you have selected.
The M3X2 Isolation Base is produced in six standard sizes and is also available in custom sizes to suit every component in the world. Each size can be purchased with any of our different footer options to optimize performance for all components.
Every HRS Isolation Base model series can be set to either transfer and dissipate energy coming to and from the component or isolate the component from the supporting structure. Each HRS Isolation Base includes either our Broadband Isolation Feet (SF), our Low Frequency Feet (LF), or our Bi-Directional Noise Reduction Feet (G7). The selection of the footer type is made to optimize the performance of each component. You can also adjust or change the footer type on each isolation base at any time to keep your system at peak performance. Please contact your authorized HRS dealer or HRS to make the final footer selection to optimize the performance of your system.
SF: HRS Broadband Isolation Feet – Isolates components from below 20 Hz to above 40k Hz. Excellent starting point for tube amplifiers, tube pre-amplifiers, DAC’s, phono pre-amps, and many turntables. Select the proper component range from the chart below. For large amplifiers and turntables, please contact HRS for custom settings.
LF: HRS Low Frequency Feet – Isolates component from below 10 Hz to above 40k Hz. Use for non-suspended turntables and when subsonic content is present and presents a potential feedback issue with the system. They are also used for custom applications where they provide additional sonic benefits. Custom setup is required for each component.
G7: HRS Bi-Directional Noise Reduction Feet – Transfers and dissipates energy coming to and from the component. Used for solid-state power supplies, power conditioners, tape machines, vacuum pumps, solid-state amplifiers, and solid-state pre-amplifiers. These can also be used if you prefer not to deal with different load ranges or where the use of chassis noise reduction products is not desired or possible. The HRS G7 feet do not have any load limit and can be used for any component.
Introducing the G-Link: The G-Links act as an ideal interface between the HRS G7 Bi-Directional Noise Reduction Feet and any floor where you do not already have an HRS frame system. The G-Link will ensure excellent coupling of the G7 equipped HRS Isolation Base to a carpeted surface or an uneven floor.
