B & C Speakers DE-85 8 OMH Driver 140W RMS, 108dB, 500-18.000 Hz

Driver 140WRMS, 108dB, 500-18.000 Hz

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 .

The B&C Speakers DE750TN-8 2" titanium HF driver is a world-class high frequency transducer that is capable of extreme output levels combined with incredible fidelity and musicality. A powerful ceramic ferrite magnet structure provides the high magnetic flux density required for the DE750TN's high efficiency, accuracy, and extended high frequency response. A copper cap on the pole piece reduces inductive losses and extends HF capabilities.
