The Bergen 2 hifi rack is designed to vastly reduce vibrations using the spike & counter spike system that Norstone have developed. This is done by creating extra rigidity through the layout of the structure & the way the shelves are fastened between the feet of the connecting uprights. The structure of the unit consists of glossy black coated steel struts with black lacquered tempered glass shelving, delivering a hard wearing, low vibrating rack for your high performance audio system.
