R1 Isolation Base

R1_IsolationBase1R1-1921 Black Anodize Finish

“The R1 Isolation Base was derived from our High Performance S1 Isolation Base design. It has the same primary isolation stage and 60% of the plinth construction combined with a new innovative top and bottom panel that offers excellent performance and value for our customers.”
-Michael Latvis
Chief Engineer
Harmonic Resolution Systems Inc.

The R1 Isolation Base is a highly innovative design that eliminates noise revealing a new level of musical performance. It is manufactured from five different materials including a proprietary resonance control stage and billet machined aircraft quality aluminum trim. The R1 load range is matched to the component weight for maximum performance just like our high performance S1 and reference level M3X design. The R1 can also be modified in the future to preserve initial investment. This is a unique product that offers our customers true Harmonic Resolution Systems performance that is derived from a decade of experience creating industry leading designs.

r1_closeThe R1 Isolation Base is produced in two 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 also offers hundreds of custom designs in our M3X Isolation Base product line
including custom designs for all large turntables and amplifiers. Please contact your local sales representative or Harmonic Resolution Systems for assistance with custom isolation bases for your components.

The broadband noise reduction system in the R1 maximizes performance and is highly effective on a wide range of surfaces and structures. The low profile compact design also minimizes space requirements. The R1 Isolation Bases Integrate directly into the HRS audio stand frames. (R1-1719, R1-1921 sizes)
