The VO-B4 is truly a PA-Style bullet tweeter designed for the mobile environment. When it comes to PA style products, many companies simply use off the shelf parts and slap their name on it, but that’s not DD’s style. We wanted to make the best sounding, easiest mounting high output tweeters on the market. That’s why we designed the VO-B3 and VO-B4. The VO-B4 custom CNC body is designed to be as short as possible to allow for easy mounting in door panels and motorcycle fairings. We also opened up the horn body compared to similarly styled tweeters. This allows you to get a wider field of sound in close proximity to the tweeter. Another unique feature of the VO-B4 is its dual mounting options. You have the option to flush mount with the trim bezel and back nut or for more space-constrained installs you can top mount using the machined screw holes in the tweeter body.
