Many Celestion LF loudspeakers feature demodulation rings to substantially reduce inductive rise as well as harmonic and intermodulation distortion
April 22, 2014
reverse this decrease by conducting away unwanted electric current, thereby reducing inductance, Le - and hence impedance - within the motor circuit.
Demodulation rings also substantially reduce the harmonic and intermodulation distortion associated with voice coil displacement.
Products such as the CF1025C mid/bass loudspeaker feature demodulation rings.
