Cox165_vPA is a professional coaxial loudspeaker, designed to cover 65 - 20 000Hz (-3dB).

Thanks the advanced motor structure, the Carbone fiber cone and the linear suspension, the mid-woofer has very low THD, and very dynamic sounding.

The compression driver uses Neodymium magnet, treated aluminum dome and integrates heat sink for better power handling.
We suggest a crossover point around 2800Hz, 12dB/Oct.
