High strength aluminum alloy material Made of solid aluminum alloy.it has excellent corrosion reistance,high temperature resistance,creep resistance and excellent characteristics of ,high hardness,and high vibration attenuation rate The key to reducing resonance The foot cushion spring is composed of seven 1mm thick stainless steel springs. With ultra-high load-bearing capacity and thick springs,it can effec-ively reduce the internal and external resonance of audio equipment,avoiding the impact of vibrationon sound qualitya Equipment shock free sound correction Why can foot nails improve sound quality ? The working principle is actually very simple,which is to increase the pressure of the box equipment by reducing the contact area,thereby suppressing the instantaneous end jump generated by vibration and stabilizing the direct wave Smalll stature makes a big difference The bottom is equipped with a thickened anti slip silicone gasket that is stable and not easy to slide.It not only does not scratch the floor,but also effectively reduces the back lash of music signals on the sound system in the air Nap Spring shock absorber foot pads Function:Reduce resonance Bottom:Diamond shaped rubber pad Applicable: Mixer,audio system,amplifier shock absorbers Color:Silver Material:Aluminum Alloy Size:about 44mm in diameter, 40mm in height Package Contents: 4 * Amplifier Shock Spikes Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
