TWEETER R3004/662000
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all
listening locations. With its large roll surround and textile diaphragm provide a flat
frequency response to above 30KHz. The unique AirCirc Magnet System, and its rear
chamber, results in elimination of reflections and resonances that compromise the
performance of traditional motors.
KEY FEATURES:
· 1" Ring Dome Diaphragm
· Patented Symmetrical Drive (SD-2) motor
· Diffraction Damping Rubber Front
· Patented Phase Plug Design
· AirCirc Motor Design w. 6 Neo magnets
· Die Cast Rubber Painted Alu Face Plate
