1 Driver mounted on B&C ME 45 horn.
2 2 hours test made with continuous pink noise signal (6 dB crest factor) within
the specified range. Power calculated on rated minimum impedance.
3 Power on Continuous Program is defined as 3 dB greater than the Nominal rating.
4 Applied RMS Voltage is set to 2.83V for 8 ohms and 4V for 16 ohms Nominal
Impedance. Average SPL from 1000 to 18000 Hz.
DE 25 | Hf Compression drivers
1" high frequency compression driver. Low mass mylar
diaphragm ensures an extremely flat frequency response and
optimized ceramic magnet assembly, results in high sensitivity
and low distortion up to 18 kHz.
5 12 dB/oct. or higher slope high-pass filter.
