1,5inch compression driver able to reproduce large bandwidth (700 - 20000Hz at +/-3dB), with a very low distortion rate (lower than 0.5%), and 106dB sensitivity.


Diaphragm is made of specifically treated and sanded titanium which avoid intense dome break-up.

Motor structure use powerfull NdFeB magnet and our dual demodulation system based on Al + Cu rings keep very low non-linearity
