The Spider is the central part of the hi-fi installation and is designed to expose, support and isolate electronic equipment. It is currently the most efficient HIFI Nortsone furniture in terms of vibration damping. The Base typically goes on the bottom then you stack the Spider 1, 2, or 3 on top depending on the size of your gear. Norstone makes bamboo tops but we only have the smoked glass for now since it is more popular. All the sizes are on this page, just choose what size you want and add to the cart.
