Pioneer's TS-W261S4 10" subwoofer is the perfect addition to your stereo system that'll be sure to add more thump. This Pioneer Champion Series sub features a ribbed cone that's injection-molded for exceptional precision and strength. A double-layered elastic polymer surround supports the woofer during cone excursion so you'll get accurate, hard-hitting bass notes even when the music's turned up loud. Wire a pair of these in parallel and they're a great match for a mono amplifier. Pioneer’s IMPP Composite Cone is newly re-designed to deliver a durable cone structure for accurate, yet powerful bass. The subwoofer now provides a single piece cone and drive cone, in addition to a lightweight and rigid dust cap. This combination offers more rigidity throughout the cone versus competitors in its class. An extremely durable, yet lightweight cone is vital to prevent cone failure at high sound pressure levels.
