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

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

To be noted

This graph shows the frequency response and the related distortion rate when our Cmp35_vPA is used with exponential horn, 180mm output diameter, 2V input signal,

We notice that THD doesn't exceed 0.5% from 1500Hz, and its main component is 2nd order, ensuring natural sounding.

The natural roll-off is located at 1000Hz, and we recommend to use it from 1800Hz with 2nd order filter.

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 80Hz to 22000Hz (-3dB).

98dB/2.8V/1m sensitivity,

350W power handling (700W music program).
