TWEETER D2004/602000
The compact size is one of the key elements of these Illuminator tweeters, which
provides a high degree of flexibility within design options. The small size is employed
without compromising sound quality where these compact tweeters are fully
comparable to the renowned full size Illuminator and Revelator tweeters, no matter if
the music is played at high or low listening levels.
KEY FEATURES:
· 3/4" Textile Dome Diaphragm
· Patented Symmetrical Drive (SD-2) motor
· Non Resonant Alu Rear Chamber
· Large Roll Surround f. Wide Dispersion
· Sound Transparant Protective Grill
· Die Cast Housing & Face Plate
