Description
26 mm Dome Tweeter
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all listening locations. Its large roll surround and TPCD dome diaphragm provide a flat frequency response to above 40KHz 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
- Bespoke tailored Thin-Ply Carbon Diaphragm (TPCD)
- AirCirc Motor Design w. 6 Neo magnets
- Patented Symmetrical Drive (SD-2) motor
- Large Roll Surround f. Wide Dispersion
- Black Anodised machined Faceplate
