Description
26mm Ring Radiator 4ohm, Neo, AirCirc, Clover
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all listening locations. 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.
Features
- 1" Ring Dome Diaphragm
- Patented Phase Plug Design
- Patented Symmetrical Drive (SD-2) motor
- AirCirc Motor Design w. 6 Neo magnets
- Diffraction Damping Rubber Front
- Die Cast Rubber Painted Alu Face Plate
