Description
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.
Features
- 3/4" Textile Dome Diaphragm
- Large Roll Surround f. Wide Dispersion
- Patented Symmetrical Drive (SD-2) motor
- Black Anodised machined Alu Faceplate
- Gold Plated Terminals
