In the SL400 Speaker Stands, Atacama have produced a sturdy construction from an award winning series. 400mm (15.8") high and made from heavy gauge steel, the rigid structure supports the use of Atacama Atabites. The Atacama SL400's are designed with larger speakers in mind, whereas the shorter models such as the SL200 and SL300, would be more suited to supporting smaller monitors and speakers. All Atacama models have identical top and base plates guaranteed along with the mass loading of Atabites to be an extremely reliable stand. Adjustable carpet spikes are supplied as standard, with top spikes available as an option. The i (isolation) versions of the SL stands come with Atacama's Isolation Gel Pads which add 10mm to the height.
