VO-B4 Super Tweeter is Now Shipping


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 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.

Install Highlight: 1994 Fiat Panda


As many of our loyal fanbase knows, DD Audio has long since been a staple in competition here in the states. That is where we made our name, and still hold our own despite the onslaught of potential competition. Just as that bass bug spread domestically the rest of the world has felt it too, just ask our man, Luuk Tissingh, from Car Audio Shop Mag ‘t wat Harder in the Netherlands!

In his shop, which opened in 2012, he and a customer embarked on a project with their 1994 Fiat Panda, aiming to build a demo monster to show what they could do with our products. To say they hit the mark would be an understatement! By the time they finished it, they had a music machine capable of doing a whopping 159dB all day with the door open, giving anyone within earshot a heavy dose of VO goodness.

Those lucky enough to have experienced this animal in person were blown away, not only by the volume and pressure it is able to generate, but the quality of the sound as well. It’s easy to see why with an equipment list like this:

It is only fitting, since Luuk first became familiar with our product in the dB Drag lanes back in 2005, that this little gem is slated for a rebuild to compete in EMMA competition this season. We look forward to seeing what kind of DD gear you stuff in it this time, and best of luck in your classes! Thanks again to the great folks at Car Audio Shop Mag ‘t wat Harder for sharing this with us, and keep up the great work!

Dealer of the Month: Green Toad Audio of Conway, Arkansas

Shop Name: Green Toad Audio
Shop Location: Conway, AR
Owner’s Name: Jeremy Smith

DD: How long have you been in business?:
Jeremy: One year.

DD: How did you get started in car audio?
Jeremy: The staff has always been audiophiles, so car audio was a natural addition to our full service automotive repair shop. My service advisor grew up in LA where his dad was a master audio installer, so he was instrumental in setting up our shop.

DD: What made you decide to do car audio for a living?
Jeremy: Our shop Green Toad Tire & Auto has built a name for drivability diagnostics and a commitment to honesty, integrity and perfection. In our city, there was a virtual hole in the car audio market for someone to become a premiere audio retailer/installer. Couple the two together and car audio just made sense.

DD: Does your shop specialize in anything specific?
Jeremy: We are known for high quality installs and only using top of the line equipment.

DD: How long have you been a DD Audio dealer?
Jeremy: Four months.

DD: Where did you first hear about DD Audio, and why did you decide to become a DD Audio Dealer?
Jeremy: When we ultimately made the decision to add car audio to our services, we wanted to sell and install the best. With that decision, becoming the DD Audio retailer was an easy one because DD Audio is synonymous with being the best in performance for competition and daily driving. Being the audiophiles that we are, we have all heard DD Audio at sound competitions, so our love for their sound began years ago.
