HRS M3X2 Isolation Base

The M3X2 Isolation Base is the latest generation of reference level Isolation Bases from Harmonic Resolution Systems. It is manufactured from six different materials including two proprietary polymers, billet machined aircraft aluminum and polished black granite.

The M3X2 load range is matched to the component weight for maximum performance and can be modified in the future to preserve initial investment. The M3X2 is the result of more than a decade of research and development into achieving true reference level audio system performance.




This unique design utilizes six different materials to optimize stiffness, geometry, mass, and impedance characteristics. Each material is carefully selected for optimum performance and functionality. The M3X2 Isolation Base also uses two different proprietary HRS elastomer formulations. The first was developed to maximize isolation efficiency, and the second was developed to control and eliminate residual energy.

A finely polished black granite contact plate is combined with two custom resonance control stages in a billet machined aircraft aluminum frame with a craftsmanship finish and black anodized coating. This exceptional design was created to offer maximum performance, cosmetic elegance, and a durable scratch resistant inlay design that will provide years of maintenance free service.

The M3X2 Isolation Base is produced in several standard sizes. Each size can be purchased in any of the four different load ranges to optimize component performance.

If one of standard sizes or load ranges does not fit your needs, HRS offers hundreds of custom designs for many different components including all large turntables and amplifiers. Please contact us for assistance with custom Isolation Bases for your components.
