HF compression driver

• Rotatable Constant Directivity waveguide
• Six available patterns with

coverage from 40º to 90º

• 100 db sensitivity, 134 db maximum SPL
• Power handling: 600 W

continuous, 2400 W peak

• Fourth-order crossover with HF protection

EVF "D" high definition systems are equipped with our

highest performance DVX series symmetric drive woofers

and the DH7N 3" pure titanium compression driver.

The result is lower distortion, cleaner sound reproduction at

a given output level, compared with the equivalent

"S" version.
