Titanium Compression Driver

The COMP-3300 compression driver features a 2” exit pure titanium diaphragm with an impregnated polymer fiber surround for high sensitivity, low distortion and a smooth extended frequency response. An optimized aluminum phase plug prevents phase cancellation problems. High flux density magnetic assembly with copper shorting ring lowers distortion and reduces the voice coil self-inductance. The compression driver’s base and cover are injected aluminum assuring high resistance.
