Exceptional speaker pad / decoupling plate made of Mustang slate 35 x 25 x 4 cm. To ensure optimal decoupling of your Hi-Fi boxes, heavy natural stone underlays are indispensable. We offer you a black natural slate stone, which not only ensures the acoustic optimisation of your system, but is also visually an eye-catcher. By decoupling the speakers from the surface, you try to make resonances of the surface, which e.g. caused by air and impact sound, do not let the housing. Absolute vibration damping is naturally not possible. Because simply disappear, you cannot vibrate. But by shifting the frequency you can weaken it, minimizing and harmonising it. The surface of the plate has a distinctive charm and absolute uniqueness. You can clearly see the structure in the photos. The surfaces of the edges are polished, chamfered.
