1inch compression driver designed for demanding design, where sound quality is more important than sensitivity.


We have designed Cmp35_vPA to provide very low distortion, and natural sounding.

Cooper ring and Aluminum ring for very low THD

It reproduces 1500Hz to 20000Hz with extreme linearity (+/-1.5dB), and 103dB sensitivity.

Application example

Loudspeakers used:

High performances line array system, using two 6" mid-woofers and a 1" compression driver.

.Koprpus_6 has be designed to deliver the best sound quality, with very low THD and free from sound coloration.

It can also be used as satellite speaker in cinema.

To be used from 70Hz to 22000Hz (-3dB).

98dB/2.8V/1m sensitivity,

350W power handling (700W music program).
