IMPP 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 new 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 (TS-W309S4) and dual voice coil (TS-W309D4) 12-inch designs. The Dual 4 ohm subwoofer has the flexibility to be wired at 2 or 8 ohms, 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.
