Динамик ВЧ SCANSPEAK R3004/662000. Инструкция на английском языке

TWEETER                                                   R3004/662000
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all
listening locations. With 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.
