The whole box is made of imported Australian pine boards+multi-layer birch boards. Repeated optimization of the box arc design improves the visual aesthetics, while improving the acoustic performance of low-frequency dispersive distortion and parasitic vibration.

The box is covered with Thai teak/ebony solid wood leather, high gloss crystal paint, and the front panel is covered with Italian science and technology grain wood leather. The whole box looks elegant and noble

The four special steel nails at the bottom, in addition to shock absorption and stabilizing the box, can effectively protect the box from moisture, improve the low-frequency condensation performance, and make the low-frequency more clean and powerful|

The grounding function is added to the system to avoid the subtle influence of electrostatic interference.
