ScanSpeak D2004, 602000 Tweeter - Illuminator Range

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.

This tweeter features a 3/4" Textile dome, patented symmetrical drive (SD-2) motor, non resonant aluminium rear chamber, a large roll surround for wide and even distribution and a sonically transparent protective grill.
