B&C DE680TN 1.4-Inch Compression Driver - 80W RMS, 8 Ohm

The B&C DE680TN is the latest version of B&C's premium 65 mm (2.5 inch) voice coil, neodymium high frequency driver. The diaphragm in this model 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.

Replacement Diaphragm: JP101971 (B&C MMD25BTN)
