Advanced coaxial , designed to cover 60 - 22 000Hz (-3dB).

The cone of the woofer uses the hexaKone technology and the reversed NBR surround avoids any diffraction for tweeter sound wave.


The tweeter is built with very light 12mm voice coil dived in twin NdFeB magnets motor, delivering 16000 Gauss.

We suggest a crossover point around 3800Hz, 12dB/Oct.

Woofer  part of Cox120_vHP is  same as Wom120_vMS.

This is wwhy Wom120_vMS is mentioned on the non-linearity graphics.
