Product Features

The R3X Isolation Base is a highly innovative design that eliminates noise, revealing a new level of musical performance. The R3X is  manufactured from five different materials including a proprietary resonance control stage and billet-machined aircraft aluminum trim. The R3X Isolation Base is initially configured at HRS to optimize the performance of a specific component and can be changed in your home to optimize the performance of a different component at any time.

The R3X Isolation Base is constructed with a CNC machined non-resonant core with strategically placed internal pockets that contain internal decoupled high mass damping systems for energy dissipation. The top and bottom plates are manufactured from custom-pressed HRS resin fabric composite. The top surface of the high-density plinth also has a scratch-resistant coating applied to the outer surface to preserve finish integrity. Encompassing the R3X perimeter is a billet-machined heat-treated aluminum alloy stiffening trim which is finished to exacting HRS standards for cosmetic elegance.  The low-profile (3-inch height) also minimizes space requirements and keeps the visual focus of your system on the components you have selected. 

The R3X Isolation Base is produced in two standard sizes and is available in a black or silver finish. Each size can be purchased with any of our different footer options to optimize performance for all components.

  • Broadband noise reduction systems maximize performance
  • Highly effective on wide range of surfaces and structures
  • Low-profile compact design minimizes space requirements
  • Standard sizes ensure full system integration
  • Can be used on any existing surface
  • Integrates directly into all HRS Audio Stands without modification
  • Easily modified to optimize performance for different component types

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. 

R3X Isolation Base with G7 Feet and G-Links

“The R3X Isolation Base is the latest version of a design derived from our S3 Isolation Base. It usesthe same noise reduction footer technology found ou our reference level M3X2 Isolation Base and shares 60% of the plinth construction with our high performance S3 Isolation Base. The R3X top and bottom plate is made from a custom HRS non resonant plate material that increased the mass density of the R3X by 28% over the previous R1 Isolation Base design. These design improvements allow the R3X to offer more of the performance achieved by its very ambitious siblings.”
