B&C DE980TN 1.4-Inch Compression Driver - 110W RMS, 8 Ohm

The B&C DE980TN is the latest version of B&C's 75mm (3.0 inch) voice coil, neodymium high frequency driver. The diaphragm in this model has been completely redesigned to incorporate a bent edge voice coil former, new dome and surround geometry and an optimized phase plug. These modifications combine to better control diaphragm displacement and deformations, resulting in lower distortion and a smoother higher frequency response above 10kHz.

Replacement Diaphragm: JP101981 (B&C MMD3DTN)
