As the newest ring radiator offering from B&C speakers, the DE360 features a ketone polymer diaphragm with a neodymium magnet motor. Extensive FEA modeling and physical testing over the last several years has culminated in these 1.5 inch (38mm) coil ring drivers with outstanding sensitivity, high frequency extension, and compactness. A practical recommended crossover point of 1.8kHz and sensitivity of 110dB in the DE360 allows for a wide range of applications, including compact two way boxes and line arrays.
