COIL GAP VENTING

Cooling vents are machined into the back plate coil gap for increased heat dissipation.

CAST ALUMINUM BASKETS

Redesigned for strength, stability, and precision. Using cast aluminum allows for added heat dissipation properties as well as high rigidity and low resonance. All these qualities combined, result in a basket that supports powerful high excursion designs.

STAMPED STEEL BASKETS

Using rigid steel with a specialized coating results in a sturdy, durable, low resonance design. Precision punched DD logos were incorporated into lower venting section.


The new Redlines serve up deeper lows along with the powerful impacts DD subs have long been known for.

200 SERIES

We designed the 200d series to have high output on as little as 100-300 Watts, enhancing the efficiency with a smooth, wide bandwidth. They’re hand built and tuned to work well in sealed enclosures as well as compact vented designs.

Available Sizes: 10″, 12″

500 SERIES

The 500d series is one of the best performing subs you can find in its power class. With a highly efficient design, the 500 series can easily be driven to high output levels on as little as 150-400 Watts. When stepping up from the 200 series, the 500’s use a longer coil, more powerful motor and the suspension is designed to handle higher transient peaks. These are very versatile subs that work well in sealed enclosures while providing the extra energy and control needed for vented enclosures applications.

Available Sizes: 6″, 8″, 10″, 12″

600 SERIES

The 600d Series is a great entry point for a higher performance system design that keeps the vehicle as close to stock as possible. The 600 Series will perform like a boss on as little as 300-600 Watts per, meaning even multiple woofer systems can be driven with one moderate powered amplifier. This keeps electrical upgrades minimal with less added strain on the vehicle. It has a high energy, double stack motor paired with a laminated triple layer poly cotton spider suspension. The 600 Series works best with vented and multi-order enclosures.

Available Sizes: 8″, 10″, 12″, 15″
