Field Coil Driver
J500 is in charge of the mid-range and produce sound with the biggest 4 inch beryllium diaphragm.
Totally CNC machined phase plug guarantees that the sound quality is up to the designer’s requirements.
Heavy field coil magnet, on the other hand, explains voicelessly of ESD Acoustic’s philosophy and pursuit.
