Premier 12" Shallow Mount Subwoofer with 1500 Watts Max. Power

  • 400 Watts Nominal Power
  • Unique Design with just 3-1/4" Mounting Depth
  • Small Enclosure Use (0.5 ~ 1.0 Cubic Feet)


Our newest line of 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 3-1/4" - less than half a typical subwoofer in this class.

This Premier® 12" shallow subwoofer handles 1500 watts max., 400 watts nominal power, 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.

To ensure that you get more natural bass, we’ve incorporated out new Basalt fiber technology into our shallow subwoofers. With the new Interlaced Basalt/Carbon Fiber Reinforced IMPP Cone, the volcanic-rock fibers create a cone that is lightweight, rigid, well damped, stable in temperature extremes, and more environmentally friendly. In short, this bass really rocks.

One of the new patent-pending features is called the "Air Suspension Control System". This design locks in air 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.

Shallow Subwoofer Enclosure   The available UD-SW12B Subwoofer Enclosure is the perfect complement for the Premier TS-SW1201S2/S4 subwoofer. It features a shallow-depth design that makes it easy to fit behind the seat of many Trucks and SUV's, or use it in any vehicle where space is at a premium.
