The VO-CTAL8 and VO-CTAL10 horns were engineered to be used with the VOW8a and VOW10a mid woofer and a CT25 or CT45 compression tweeter to offer a compact, full-range, high output solution. Made of precision machined aluminum and finished with red anodizing, the horn’s design allows for an energetic yet smooth response over the compression tweeter’s frequency range. By using aluminum instead of plastic the horn is more durable, acts as shorting ring, and aids in the driver’s thermal handling.
Horn, Woofer, and Compression Tweeter Sold Separately.

Adding that DD sound to your car has never been so easy. If you don’t have the means or time to construct an enclosure for your DD subs then these DdBox spec enclosures are all one needs to quickly and easily add great bass to your vehicle. They’re available in loaded and unloaded versions, so no matter what level of bass you’re craving there’s a pre-fab DD Box that will be right for your application.
Building a great sounding mobile audio system doesn’t end once you’ve acquired the necessary DD Audio components. If you want your equipment to sound like it was intended to you still need to optimize the install environment. All of our installation accessories utilize the best materials available and are designed with the installer and the peak performance of the equipment in mind.
To achieve the desired system performance it’s sometimes necessary to alter the audio signal from its pre-amp or post-amp waveform. DD offers a full line of passive and active solutions allowing you to bend those frequencies to your will.
No matter the specific application DD Audio offers an amplifier to cover your needs. Our amplifier designs emphasize high performance, functionality and reliability. All DD Audio amplifiers are built using industry leading part manufacturers and are held to the highest level of build quality. You can rest assured when your system is powered by DD Audio, you’re using the best power on the planet.
DD coaxial and component speakers utilize sound quality design features coupled with high energy motor systems to set the standard for aftermarket audio upgrades. All DD speakers incorporate Faraday rings, high temperature voice coil wire, state of the art cone technology, and countless hours of R&D time. All these features come together to give you the sound to truly enjoy the ride.
It is the goal of DD Audio to create the finest audio products possible, dedicated to the ultimate performance of the product no matter the lengths required of the design or manufacturing process.
This motor system also utilizes the DD exclusive FREE FLOW COOLING SYSTEM; separate cooling vents machined into the voice coil, top plate and pole piece which focus cooling air into the magnetic gap. This high-tech, precision machined cooling system actually lowers the working temperature of the voice coil, thereby lowering the stress on the entire audio system. The more the speaker moves, the more air is pumped onto the coil wire.
The dustcap and spiders of a speaker create changes in air pressure as the cone system moves up and down in accordance with the input signal, and the amount of movement is proportional to the amount of input signal.
The dustcap is used to push cooling air down through the pole piece. The pole piece has cross ventilation passages machined from the center vent to the outside of the pole piece, with rows vent holes at the top and bottom of the pole. Cooling air is pumped directly onto the aluminum former as well as drawing heated air out of the magnet cavity.
The spiders are used as forced air pumps o channel air through vents machined into the top plate inner diameter. These vents move cooling air directly to the voice coil wire. Additional vents are machined from the top plate inner dimension to the outside of the top plate and work in conjunction with vents tooled into the speaker baskets.
The voice coils are also part of the Free Flow Cooling System with rows of cooling vents located above the coil windings, below the coil windings and at the top of the former in the dustcap cavity. Cooling air is pumped through these rows of holes to move heat away from the wire; as close as possible to the source of heat.
The surround uses our EROM( Extended Range Of Motion) profile, copied en masse to become an industry wide standard. The EROM design gives long, controlled excursion while keeping the cone diameter as large as possible. This profile also saves mass over the sculpted rubber surrounds and inner tube style surrounds, less mass is louder and faster.
The EROM profile, nearly parallel walls with a half-round top, is more self-supporting than the wide half-roll type surrounds. This enables the surround to become part of the suspension compliance, helping to control the high forces of the accelerating moving mass and enabling the coil to better track incoming signal.
The DD EROM profile innovation allows for more cone area, lower mass and increased stiffness. It’s no wonder than the DD EROM has become the most copied surround in the world.
As current flows through the voice coil, it generates its own magnetic field which interacts, or modulates the motor’s permanent magnet field. A shorting ring cancels these magnetic field changes and lowers inductance, extending the frequency range and reducing harmonic distortion.
