For 2013, Pioneer announced four new Champion Series automotive subwoofers which use a prism patterned IMPP Composite Seamless Cone, new drive cone construction, and improved flange assembly for maximum installation flexibility. The new models include the TS-W260S4 (10-inch), TS-W260D4 (10-inch), TS-W310S4 (12-inch) and TS-W310D4 (12-inch). Available in 10- and 12-inch versions and with dual or single 4-ohm voice coils, Champion car subwoofers produce more air movement without unwanted flexing or “buckling” effects that can create distortion.
The new cone design is further reinforced by a new dual-layer Elastic Polymer Surround technology that is light and flexible yet dramatically more durable, resulting in a subwoofer that can reliably provide strong bass output.
Internal components of the subwoofer were also improved by using a four-layer copper voice coil with an aluminum former that improves heat dissipation for higher input power handling and increased reliability. Additionally, the subwoofer design incorporates air vents in the metal basket construction below the spider to help further cool the voice coil.
