1 Driver mounted on B&C ME 75 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 500 to 18000 Hz.
DE 85 | Hf Compression drivers
5 12 dB/oct. or higher slope high-pass filter.
2" high frequency compression driver. The particular mylar/titanium
diaphragm using a 3" edgewound flat aluminium wire voice coil and a
optimized high energy ceramic magnet assembly using a copper shorting
ring assembly produce smooth response and excellent sonic properties .
