The Libra PRO Series rack synthesizes four core acoustic principles: ‌Mass Loading‌ (increasing inertia), ‌High Rigidity Constraint‌ (inhibiting deformation), ‌Damping Dissipation‌ (absorbing energy), and ‌Acoustic Impedance Mismatch‌ (reflecting vibrations).

Through advanced composite material design, the rack transcends its role as a passive tool, transforming into an active ‌precision platform‌ that ‌actively manages‌ vibrations. This optimized foundation significantly enhances the audio performance of your playback equipment by minimizing disruptive energy transfer.

The internal structure of the rack adopts a high-damping design (damping ratio: 0.1). 

Subtle mechanical vibration energy can be efficiently absorbed by the rack, converted into thermal energy and dissipated, without being transmitted to other equipment or interfering with the original device in turn. 

This design significantly improves the background quietness.

When the rack is unloaded, its dominant modal frequency is below 500 Hz, with the first-order modal frequency at approximately 72 Hz.

When fully loaded with equipment, the first-order modal frequency is around 42 Hz.

This structure ensures that the rack maintains excellent low-frequency characteristics under the load-bearing capacity of most current products, achieving outstanding vibration isolation performance for audio frequencies above 42 Hz. For frequencies below 42 Hz, thanks to its superior stiffness and damping design, it provides exceptional control over intense vibrations induced by audio or other external factors.
