1、Aluminum Alloy Material: Speaker isolation feet pads are made of aluminum alloy, with high hardness and high density, with low harmonic vibration point and high damping, no adhesive, practical and reliable. 2、Improved Sound Clarity: Speaker isolation feet pads are designed with skid plate rubber that absorbs vibrations for higher quality listening pleasure, improved sound clarity, stereo imaging and bass response. 3、Steel Ball Shock Absorber: Aluminum alloy and ball as a whole, aluminum alloy itself eliminates part of the vibration, the rest of the vibration is exported to the ball to eliminate it, to obtain both HiFi and musicality. 4、CNC Machining: Aluminum HiFi turntable isolation feet pad adopts CNC machining, which is easier to install, no need to punch holes, no need to use double sided tape, so as not to damage your equipment. 5、Pause Acoustic Feedback, Isolate Vibration: The steel ball speaker pad pauses acoustic feedback from speakers or subwoofers to isolate vibration. The sound is more concentrated, lighter and less noisy. 6、Scope of Application: Stainless steel ball speaker pad is widely used in speakers, power amplifiers, instruments, turntables, CD DVD players, recorders, DACs and other equipment.
