The Auralex ProPADs are a premium version of their current, best-selling, MoPADs. They feature a durable, three-layer, highly damped construction that provides superior isolation from the vibrations and resonant energy created by studio monitors, which prevents this energy from being transmitted into the supporting furniture. The new design also features a ¾" Melamine-wrapped MDF base covered with a thick layer of ISO-Plate™, which is made from 100% recycled rubber.
