Product Description

HARMOTECH H7.3 ( TWEETER )


     The HARMOTECH H7.3 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.

 

1" Textile Dome Diaphragm

Patented Symmetrical Drive (SD-2) motor

Die Cast Rubber Painted Alu Face Plate

—Large Roll Surround f. Wide Dispersion

AirCirc Motor Design w. 6 Neo magnets
