VO-B4 Super Tweeter is Now Shipping

January 18, 2018

Oklahoma City, OK, January 18, 2018 — DD Audio’s VO-B4 is now shipping to authorized dealers. The VO-B4 is the follow up to the very popular VO-B3 super tweeter. When comparing the VO-B3 to the VO-B4, customers will notice increased frequency response, efficiency, and max power handling. This was accomplished by using a larger diaphragm and voice coupled to a stronger motor. The VO-B4 is truly a high-output, PA-Style, bullet tweeter designed for the mobile environment. The VO-B4’s custom CNC machined body and die-cast motor are designed to be as short as possible to allow for easy mounting in door panels and motorcycle applications. The B4’s horn body is designed to project a wider field of sound in close proximity when compared to similarly styled tweeters. Another unique feature of the VO-B4 is its dual mounting options. The installer has the option to flush mount with the trim bezel and back nut, or for more space-constrained installs it can be top mounted using the machined screw holes in the tweeter body.
