US-based Critical Mass Systems crafts highly effective eye-catching precision “vibration mitigation systems” that manage the flow of vibration in out of components and the rack architecture that supports them. Internal filtering materials help mitigate vibration in the floor, the rack, the shelf and the component while maintaining even energy transfer. Critical Mass System’s many products include handsome racks, shelves, and footers.

Originally known for their ceramic and stainless-steel isolation devices, which prevent vibration transfer between components and the surfaces beneath them, Minnesota-based Stillpoints also manufactures Aperture acoustic panels whose absorption materials and unique internal chambers act as all-in-one absorbers, diffusers, and resonators. Performance specifications of the Stillpoints Aperture continually adapt to the dynamic changes in amplitude and frequency of audio systems while generating wave forms within the acoustical environment. If you attend audio shows, you’ll see Stillpoints Aperture panels in room after room, both at first reflection points and other problematic areas. Effective from 40Hz to 40kHz, the panels can be decorated with artwork or photographs of your choice.
