TWEETER
D3004/662000
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all
listening locations. Its large roll surround and textile dome diaphragm provides a flat
frequency response to above 30KHz with outstanding off-axis dispersion. 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" Textile Dome Diaphragm
Magnet System w. Alu Ring
Diffraction Damping Rubber Front
Large Roll Surround f. Wide Dispersion
AirCirc Motor Design w. 6 Neo magnets
Die Cast Rubber Painted Alu Face Plate
