The M3X 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 aluminums, and polished black granite. The M3X load range is matched to the component weight for maximum performance and can be modified in the future to preserve initial investment. The M3X 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 M3 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 anodize 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 M3X Isolation Base is produced in four standard sizes. Each size can be purchased in any of the three 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 your local sales representative or Harmonic Resolution Systems for assistance with custom isolation bases for your components.
