B&C DE1090TN 1.4-Inch Compression Driver - 120W RMS, 8 Ohm

The B&C DE1090TN is the latest version of B&C's premium 100mm (4.0 inch) voice coil, neodymium high frequency driver. The compact 127mm diameter was achieved using a specially designed inside ring neodymium magnet. The diaphragm used in DE1090TN has been completely redesigned to incorporate a bent edge voice coil former, as well as new dome and surround geometry. These modifications combine to better control diaphragm displacement and deformations, resulting in lower distortion and a smoother higher frequency response above 10kHz.
