DD Audio VO-B4A Voice Optimized High-Output Bullet Tweeters

Get the highs your high-output car audio system needs with the DD Audio VO-B4A Voice Optimized Bullet Tweeters. Designed for loud car, truck, motorcycle, and custom pro-audio systems, the VO-B4A combines a 38.6mm voice coil, titanium diaphragm, neodymium motor, CNC-machined aluminum body, 108 dB sensitivity, and 2kHz–20kHz frequency response.

Each VO-B4A handles 50 watts RMS and 150 watts peak at 4 ohms. Their extremely high 108 dB sensitivity makes these tweeters an excellent choice for systems where the highs need to keep up with powerful midrange speakers and subwoofers.

If you're searching for where to buy DD Audio VO-B4A tweeters, shop East Car Audio. East Car Audio specializes in high-output car and truck audio and already carries the VO-B4A alongside DD Audio speakers, amplifiers, subwoofers and other equipment for complete custom builds.

🔥 108 dB Sensitivity — Built to Get LOUD

The standout specification of the DD Audio VO-B4A is its impressive 108 dB sensitivity.

High sensitivity allows the tweeter to produce substantial acoustic output with relatively little amplifier power. In a system with multiple high-output mids, powerful subwoofers, custom door panels or speaker racks, that efficiency helps the highs remain present instead of getting buried by the rest of the system.

DD Audio specifically developed the VO-B4 as a high-output, PA-style bullet tweeter designed for the mobile environment.

🔊 Titanium Diaphragm + Neodymium Motor

The VO-B4A uses a titanium diaphragm paired with a 37-ounce neodymium motor and 38.6mm CCA voice coil.

DD Audio combines these components with a custom CNC-machined aluminum body to achieve strong output while keeping the tweeter compact enough for mobile installations.

The result is a tweeter designed for crisp, aggressive high-frequency output in loud pro-audio-style systems.

🎶 2,000 Hz – 20,000 Hz Frequency Response

DD Audio rates the VO-B4A from:

2kHz – 20kHz

This broad high-frequency range makes the VO-B4A a strong match for Voice Optimized midrange speakers in systems designed around maximum output and clarity.

Proper crossover setup is important. DD Audio's published information identifies the VO-B4A as a tweeter, so it should not be operated as a full-range speaker.

🚪 Perfect for Custom Door Panels & Speaker Racks

The compact VO-B4A works especially well in high-output installations such as custom door panels, speaker pods, motorcycle fairings, custom consoles, speaker racks and demo builds.

DD Audio specifically designed the B4's horn to project a wider field of sound at close distances than similarly styled tweeters.

This makes it especially useful when the listener is relatively close to the tweeters—as is normally the case inside a vehicle.

🔧 Dual Mounting Options

Installation flexibility is another major advantage.

DD Audio designed the VO-B4A so installers can flush mount it using the trim bezel and back nut or use the machined mounting holes for a top-mounted installation when space is limited.

The current DD Audio specification table lists a 1-15/16" mounting diameter and 1-3/8" mounting depth.

📦 What's Included

Your current East Car Audio listing is for a PAIR, so I would make this extremely obvious near the price:

2 × DD Audio VO-B4A Voice Optimized Bullet Tweeters

🔥 SOLD AS A PAIR — YOU RECEIVE 2 TWEETERS

Your East Car Audio tweeter collection currently identifies the VO-B4A listing as a pair.

🚚 Great for Loud Car & Truck Audio Builds

The DD Audio VO-B4A is a particularly good match for high-output systems in:

Chevy Silverado • GMC Sierra • Ford F-150 • Ford F-250 • Ram Trucks • Cars • SUVs • Motorcycles • Custom Audio Builds

These are potential custom applications rather than guaranteed factory-fit applications. Always check the mounting dimensions and available installation space.

For your East Car Audio customers, I would also internally link this listing to DD Audio VO Series midrange speakers. That helps shoppers build a complete mids-and-highs system and gives Google additional context about the relationship between your products.
