Designed for high-performance gear High-performance audio gear can be affected by even minor vibrations transmitted through the floor. The Solidsteel S3-4 audio stand uses quality materials and construction to keep your components in a virtually vibration-free environment. The four open shelves are ideal for oversized audio components, such as a power amp, preamp, or power conditioner. Quality construction Each shelf is made of thick vibration-damping MDF (Medium Density Fiberboard). The supporting aluminum pillars are packed with damping material for added stability and to prevent the transmission of vibrations. Both the pillars and the shelves are coated with a polymer laminate, which further damps vibrations. The four pillars rest on solid steel carpet spikes that virtually isolate the stand - and the components it holds - from vibrations transmitted through the floor.
