Double-layer stainless steel, with triangular steel ball suspended shock-absorbing vibration particles in the middle, and rubber anti-slip gasket at the bottom. The multi-layer structure reduces the energy consumed by vibration and creates a stronger sense of contrast. The working principle IS actually very simple, that is, by reducing the contact area and increasing the pressure of the speaker equipment, thereby suppressing the instantaneous end-jump stable direct wave generated by the vibration. It also absorbs and attenuates the vibration of the equipment itself and blocks external vibrations.To achieve these two points, the materials used in shock absorber must have the characteristics of high quality, high hardness, and high vibration attenuation rate. The contact surface with the equipment uses rubber rings to increase friction and reduce resonance, better protecting the equipment from damage. The tone is warm and delicate at high frequencies, smooth and pleasant to the ear, with a good sense of air, layered low frequencies, deep dive and elasticity.<br><br>type: B-M8 Foot Nail Material: Stainless steel colour: Silver<br><br>Package Contents: 1 x M8 Foot Nail<br><br>Only the above package content, other products are not included.
