DD Audio 712-D2 12″ Subwoofer

More bass. More power. Greater flexibility.

Get powerful, punchy bass in your car ? from the pedigree of world record-breaking subs.

The TS-W310D4 features a combined IMPP cone, which makes the body ultra-rigid yet lightweight, giving you low distortion and powerful bass at high sound press levels.

MPP Composite Seamless Cone
An extremely durable, yet lightweight cone is vital to prevent cone failure at high sound pressure levels. Pioneer?s New IMPP Composite Seamless Cones meet this need perfectly while delivering accurate yet powerful bass.

Dual-Layer Elastic Polymer Surround
Another world?s first from Pioneer. Dramatically improves durability and lightness for superior response, especially for louder volume.

Large Surface Area
A speaker cone is essential for air to vibrate and carry sound to listeners? ears. Our Champion Series subwoofer cones have 14% more surface area than conventional subwoofer cones, for louder, better bass reproduction.

Single/Dual Voice Coil Design
Pioneer offers single voice coil and dual voice coil designs. The Dual 4 ? subwoofer has the flexibility to be wired at 2 or 8 ?, to get the most from the amplifier. To simplify installation even further, all speaker terminals have been placed on one side of the subwoofer rather than on opposite sides.

Air Vent
The movement of air within the subwoofer is smoothly channeled for optimal ventilation to ensure a quick response and clear reproduction of bass.

Other Features
? Extra-tough suspension for high durability to withstand high input power.
? 4-Layer Copper voice coil with aluminium former for improved heat dissipation.
? Subwoofer design allows for flexible in-car installation in a box or in a free-air type application.
