DE640U
1.4 inch exit
NEW
The DE640U ring radiator high frequency driver features a Upilex (Polyimide) diaphragm with a neodymium magnet motor. Extensive FEA modelling and physical testing over the last several years has culminated in these 2.5 inch (64mm) coil, ring radiator drivers with outstanding sensitivity, high frequency extension, and compactness. A practical recommended crossover point of 1.2kHz and sensitivity of 109dB allow the DE640U to be suitable for a wide range of applications, including compact two way point source boxes and line arrays. Also available, DE640P, with HT Polymer diaphragm.
