Tuna Shock Absorbing Foot Pegs – Why We Choose 316L Stainless Steel
316L is a molybdenum-containing stainless steel grade. Thanks to its molybdenum composition, it outperforms 301 and 304 stainless steel in overall performance. It delivers outstanding pitting corrosion resistance, great high-temperature tolerance and excellent creep resistance. It features a sleek, glossy and smooth surface finish, along with premium quality, high hardness and superior vibration damping efficiency. Its material cost is twice that of 304 stainless steel.
Optimized Arc Head Design for Better Performance
The upgraded curved head structure of the foot stud enables smoother and faster standing wave diversion, bringing you a far more noticeable shock absorption effect.
Why Do Speakers Need Vibration Isolation?
Vibration from the speaker cone causes cabinet resonance and introduces sound coloration. The speaker driver itself is a vibrating component. In addition, sound waves emitted by the speaker will hit audio equipment and trigger extra vibration. Even tiny vibrations can degrade sound quality noticeably. Audio gear is highly sensitive to vibrations, which will compromise overall playback performance. To eliminate such adverse effects on sound, besides the built-in anti-vibration structures of audio devices, external vibration-damping accessories are developed to offset vibration interference and restore pure sound.
Working Principle of Tuna Vibration Isolation Foot Studs
 The principle is quite straightforward. By reducing the contact area, it increases the pressure borne by your speaker equipment. This restrains instant tip jump caused by vibration and stabilizes direct sound waves. It absorbs and dissipates internal vibration generated by your audio device, while blocking external incoming vibration at the same time.
To achieve the above two effects, the foot stud material must feature premium quality, high hardness and excellent vibration damping performance. When your audio device is running, the foot studs serve as the concentration point of vibration. We can compare this effect to calming a storm inside a teacup, making vibration elimination extremely critical.
316L stainless steel boasts far superior vibration damping capacity than alternative materials, maximizing the vibration reduction effect to the fullest.As a top-tier premium stainless steel, 316L outperforms 304 stainless steel by a large margin.
