Kuzma isolation platforms are available in two sizes: PLATIS 54 and PLATIS 65. Both sizes are passive and designed to reduce vibrations reaching audio components. The base frame is made of solid aluminum with adjustable feet, while the top plate is a hard laminated plate reinforced with aluminum. ( The top plate can be purchased separately). Silicone and aluminum dampers separate the upper plate and lower frame to filter vibrations.
