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 and dual voice coil designs. The Dual 4 Ω subwoofer has the flexibility to be wired at 2 or 8 Ω, 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.
