DESCRIPTION
The DE680TN is the latest version of our premium 65 mm (2.5 in) 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.
