Phoenix is the second flagship of the ESD Acoustic and is the system with the most units under the brand. There are ten units per channel with five sound channels, five of which are beryllium diaphragm horn units and five are titanium sandwich composite diaphragm cone units.The world's only calendered beryllium diaphragms by Truextent, with higher resolution and lower distortion, are applied on mid-range, tweeter, and super 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 field coil loudspeaker unit with a magnetic density of 2.2T, powerful magnetic flux controls the loudspeaker with ease.The carbon fiber horn has no sound dyeing, and the mid-frequency is rounded.Uncompromising cabinet design, all aviation aluminum CNC precision machining, and through the simulation design of the lining reinforcement ribs, anti-resonance materials, the cabinet sound dyeing is minimized.The innovative combination mode of active crossover and passive crossover makes the whole range smoother, and the sound is more natural and relaxed.At the 2019 Munich International High-end Audio Exhibition (HIGH END 2019), French media Audiophile Magazine evaluated Phoenix as the best speaker in the audience except for the ESD Acoustic’s Dragon system.
