Description
26mm Dome Tweeter 4ohm, Neo, AirCirc
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all listening locations. Its large roll surround and textile dome diaphragm provide 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.
Features
- 1" Textile Dome Diaphragm
- Large Roll Surround f. Wide Dispersion
- Patented Symmetrical Drive (SD-2) motor
- AirCirc Motor Design w. 6 Neo magnets
- Die Cast Rubber Painted Alu Face Plate
