The B&C Speakers DE750TN-8 2" titanium HF driver is a world-class high frequency transducer that is capable of extreme output levels combined with incredible fidelity and musicality. A powerful ceramic ferrite magnet structure provides the high magnetic flux density required for the DE750TN's high efficiency, accuracy, and extended high frequency response. A copper cap on the pole piece reduces inductive losses and extends HF capabilities.
