ScanSpeak D3004, 660000 Tweeter - Illuminator Range

ScanSpeak D3004, 660000 Tweeter - Illuminator Range

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.

This tweeter features a 1" Textile dome, patented symetrical drive (SD-2) motor, Die cast rubber painted aluminium face plate, a large roll surround for wide and even distribution and AirCirc motor design with 6 Neo Magnets.
