Alpine SWR-T12 12' Thin Subwoofer (4Ω)

The Type-R Thin subwoofer series combines the intense low-bass performance and ground-shaking output of the traditional Type-R subwoofers in a thin package optimized for extremely small enclosures.

More Mounting Options without Compromise

The Type-R Thin series have been engineered to offer more installation flexibility and application versatility to build the ideal sound system. At 3-1/4” deep for the 10” and 3-1/2” deep for the 12”, these subs provide deep bass performance where it normally couldn’t fit. And the 0.35 cubic foot (SWR-T10) and 0.6 cubic foot (SWR-T12) ideal enclosure sizes mean great bass performance can go just about anywhere in your vehicle.

Exclusive Alpine Technologies Ensure High Performance

The new Type-R Thin boasts no less than 7 unique Alpine technologies in its industry-first design. These innovations allow the Type-R Thin to have the output and power handling of the traditional Type-R series in less than half the depth. The new Type-R Thin design has the same DNA of the standard Type-Rs - demanding cleaner, deeper bass extension, faster, more accurate transients and even greater output capability.

Revolutionary Segmented Spider Design Provides the Excursion of a Tall Subwoofer

You can count on Type-R Thins to deliver strong, impactful output like its predecessors. Most shallow-mount subwoofers have less output than traditional deep subwoofers, since their shallow frame limits how far their cones can move at high power levels. The Type-R Thin uses Alpine’s patent pending Pass-Through Gap Geometry, allowing the unique Thermoplastic Elastomer Segmented Spider to completely pass through the motor structure. This means the cone and voice coil assembly have the clearance needed for over 50mm of peak-to-peak excursion, allowing for massive output even in such a shallow frame.

Consistent, Reliable Performance out of the Box

There’s no need to play your sub for hours to break it in to achieve consistent performance. This sub is designed to deliver consistent performance right out of the box. Since this revolutionary design is made with an injection mold resin, rather than phenolic stiffened textile, this new spider requires no break in to achieve ideal performance. A Co-Molded Aluminum collar attaches the voice coil to the spider to ensure a reliable, high-strength design.

These two graphs are from the industry standard measuring system, Klippel which illustrates the excursion of the subwoofer both relative to the strength of the magnet system, and the stiffness and linearity of the suspension.
