DE 750 |Hf Compression drivers
2" high frequency compression driver. The particular
mylar/titanium diaphragm using a 3" edgewound flat aluminium
wire voice coil and a optimized very high energy ceramic magnet
assembly using a copper shorting ring produce smooth
response, very high efficiency and outstanding sonic properties.
Recommended for low crossover frequencies.
