More from HRS:

The new 51 lb S3 (1921 size) plinth construction is manufactured by laminating in a vacuum press alternating layers of high density fabric reinforced resin and non magnetic stainless steel plates on both sides of a decoupled mass energy dissipation core system. The very top skin of the S3 plinth is the same high quality scratch resistant surface layer used in the R3X Isolation Base providing an identical cosmetic match. The S3 also uses the same primary isolation stage of the reference level M3X model and thus provides exceptional performance and a great performance value.

The broadband noise reduction system in the S3 is optimized to the weight of your component. The weight range can also be easily modified in the future to keep your system operating at peak performance. The low profile 3-inch high compact design also minimizes space requirements and keeps the visual focus of your system on the component. The S3 Isolation Bases can be used on any surface or audio stand and integrates directly into any of the HRS Audio Stand Frames.
