Quadraspire floor protectors/spike shoes are made from stainless steel with an absorbtion material sanwiched between the spike absorber to neutralise the adverse effects arising from contact vibration resonance and therefore improve sound quality and acoustic insulation. Naturally there is a hole on the upper surface to locate the spike and on its lower surface, a non slip membrane designed to protect delicate floor coverings and aid sound dampening.
These Isolation supports are beautifuly designed. Each spike shoe has a diameter of about 30mm, making them suitable for most speaker stands and Hi-Fi rack applications with a overall maximum weight spread over all four shoes of about 125KG.
