Extended frequency response past 20 kHz provides exceptional airiness and spatial quality with superb transients and micro- instrumentation. The result is a subtle, detailed, dynamic tweeter with fast response but without the typical harshness of metal domes that can cause listener fatigue. Low resonance, very high output, excellent power handling and protective grille, compact facia for high density facias.
