Product Details

Pioneer TS-SW841D 8" 500W Shallow Mount Subwoofer 4 Ohm

Pioneer's TS-SW841D 8" shallow mount subwoofer is designed to provide wider installation options for a broad range of vehicles. The TS-SW741D features 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 2-1/2", which is less than half that of a typical subwoofer in this class.

This 8" shallow subwoofer handles 500 watts max, 120 watts RMS, and delivers deep bass with top-notch sound quality thanks to features like Pioneer's extremely strong and lightweight IMPP Composite Double Cone Woofer, the patent-pending M-shaped surround, and more. Compatible with sealed enclosures as small as 0.15 cubic feet or for use in free-air applications.

One of their new patent-pending features is called the "Air Suspension Control System". This design locks air in-between the main cone and drive cone, ensuring smoother and more precise movement of the cones, for superior linearity. The locked-in air behaves like a spring, so there's no need for a traditional spider structure. The drive cone also deflects air pressure inside the enclosure, which further contributes to the remarkable bass of the small package.

Includes six self-tapping screws for subwoofer mounting.
