This DX family tweeter features a 4 ohm 0.75 inch voice coil, a damped silk diaphragm with large surround roll to produce a low resonant frequency, and is mounted in a NdFeB motor. The tweeter also features a rear chamber to create extended low frequency response. The faceplate features recessed mounting holes to minimize reflections.
