Panda (PANDA) is a series of bookshelf boxes of ESD Acoustic, which is divided into two types: Panda Plus and Panda.The world's only calendered beryllium diaphragms by Truextent, with higher resolution and lower distortion, are applied on tweeter units.Exclusive titanium sandwich bass diaphragms are light and strong, which eliminates segmentation distortion and phase distortion.The field coil power supply with built-in AI technology basically offsets the back electromotive force and solves a century-old problem.The speaker unit with a magnetic density of 2.2T, powerful magnetic flux controls the speaker with ease.Uncompromising cabinet design, all aviation aluminum CNC precision machining, and through the simulation design of lining reinforcement ribs, anti-resonance materials, the cabinet sound staining is minimized.Panda Plus has a dumbbell-style double bass structure. Compared with Panda, it has higher sensitivity, more accurate imaging, and deeper low-frequency diving.
