TWEETER                                                   D3004/664000
The Illuminator tweeters stand for superb vocal rendition and excellent imaging at all
listening levels. The D3004/664000 is "top of the range" with its pure beryllium
diaphragm, large roll surround, and AirCirc motor system, it provide a excellent -
unsurpassed - sound reproduction with a flat frequency response to above 40KHz,
outstanding off-axis response, low distortion and dynamic precision.
