Cox135_vPA-S is a high quality coaxial loudspeaker with low-midrange and tweeter dedicated to demanding compact application.
Thanks to the advanced pole pieces geometry and specific membranes, it provides clear and neutral sound reproduction from 180Hz to 20 000Hz, and very low THD.
We suggest a crossover point around 4000Hz, 12dB/Oct between low-midrange and tweeter.
