Stillpoints Universal Resonance Dampers are sophisticated vibration control devices. The ceramic ball-bearing on top is placed over a second layer of bearings. The top ball pushes the second layer balls outward into a series of petals causing vibration energy to be dissipated into heat.
Stillpoints will support almost any component, including heavy speakers and amps. Stillpoints heighten transparency, speed of transience, air, space, and dynamics for a very natural presentation.
($360 if order 2 sets).
