Product Spotlight: VO-B4 Super Tweeter

February 28, 2018
DD Audio Product Spotlight | WRITTEN BY KEVIN DOYLE | February 2018

Ever since we introduced the VO-B3 to our customers it’s been one of our most popular tweeters ever! So, why not up the ante with a bigger, louder version? Behold, the VO-B4 SUPER TWEETER!

SPL vs Freq Chart

When comparing the VO-B3 to the VO-B4, customers will notice increased frequency response, higher efficiency and a higher max power handling. This was accomplished by using a larger diaphragm and voice coil 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 similar styled tweeters. Another unique feature of the VO-B4 is it’s 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.
