Our line of shallow subwoofers are designed to provide wider installation options for a broad range of vehicles. These shallow-mount subwoofers feature multiple patent-pending features to deliver the big bass performance of a full-size subwoofer, but in a compact design that can be installed either behind or under seats depending on the type of vehicle. The mounting depth is just 3-1/8" - less than half a typical subwoofer in this class. This 10" shallow subwoofer handles 1,200 watts max., 300 watts nominal power, and delivers deep bass with top-notch sound quality thanks to features like Pioneer's MICA injection-molded resin which gives it the ability to produce accurate bass. Oversized Cone Surface The TS-SW2502S4 utilizes an oversized cone structure that provides greater cone and gasket surface without changing its standard external dimension. This cone surface allows the subwoofer to produce louder and deeper bass by moving more air. Reinforced Cone Structure The cone structure of this subwoofer uses a highly rigid cone made with MICA injected molded resin which creates a rigid and durable cone, giving it the ability to produce accurate bass. Shallow Compact Design Designed to perform in small enclosures or spaces that traditional subwoofers can't fit, like behind the backseat of pick-ups, the TS-SW2502S4 can produce a lot of bass without having to sacrifice space in a trunk or truck cab. Need an enclosure? The UD-SW250D downfiring shallow subwoofer enclosure or the UD-SW250T behind-the-seat shallow subwoofer enclosure are the perfect companions for the TS-SW2502S4. The innovative, compact, space-saving enclosure design makes it easy for the UD-SW250D or the UD-SW250T to be installed freely in a variety of automobile trunk spaces or inside pickup truck cabins.
