A sturdy home for your audio gear High-performance audio gear can be affected by even minor vibrations transmitted through the floor. The Solidsteel S2-4 audio stand uses quality materials and construction to minimize those vibrations. The four open shelves are ideal for oversized audio components, such as a power amp, preamp, or power conditioner. Quality construction S2-series stands are Solidsteel's most affordable, but they're still solidly built with audio performance in mind. Each shelf is made of vibration-damping MDF (Medium Density Fiberboard), and supported by aluminum pillars. The pillars rest on solid steel carpet spikes that virtually isolate the stand - and the components it holds - from vibrations transmitted through the floor.
