Ohio-Class XL+²

The Ohio-Class XL+² isoBASE™ sits at the top of our Ohio-Class series of products. An all-out assault on vibration’s ill effects, these cost-no-object platforms make full use of our cutting-edge Component Specific Design™ technology.

In creating an Ohio-Class XL+² isoBASE, we incorporate a wide range of proprietary techniques, state-of-the-art materials, and a revolutionary modeling system. Each component-specific Ohio-Class XL+² isoBASE is a custom-made product. Of course we utilize component-specific information, but we also pay close attention to room specifics and the role that psycho-acoustics plays in the listening experience. Simply put, an Ohio-Class XL+² isoBASE addresses what can and cannot be heard.

At the heart of an Ohio-Class XL+² isoBASE is our enormously complex Raft Isolation System™. Dynamic by design, the Raft Isolation System has the ability to change its isolation properties as required—a remarkable (and proprietary) feature comprising a series of complicated thermal reactions. This ability to instantly change in order to optimize component performance is utterly unique and makes the Ohio-Class XL+² isoBASE a significant addition to your sound system. Welcome to sonic truth. Welcome to Ohio-Class XL+².

Should you change components, Silent Running Audio offers free lifetime recalibration of your Ohio-Class XL+² isoBASE to the original owner.  Recalibration is performed within the dimensions of the original chassis.

Because each is custom-crafted for the component it serves, an Ohio-Class XL+² platform will vary in size and weight. For detailed information, contact your dealer, distributor, or SRA directly. The standard color for all SRA isolation stands, is Gloss Black. Other colors may be available, but with additional lead times and cost.
