What good is a shallow-mount sub if it doesn't move air? Alpine's Type-R Thin subwoofers combine low-profile design with high power handling to pump out powerful bass in your vehicle's hard-to-fit spaces. These shallow subs offer a mounting depth of 3.5 inches, but their cone excursion is nearly as long as that of their regular counterparts — you'll hear deep, satisfying bass from the resulting massive air movement.

Big bass, not much space
The special spider design uses a series of adjacent rolls to get the cone moving without requiring a lot of space, combining with the advanced motor structure that reduces the sub's profile while maintaining accuracy. A dynamic neodymium magnet structure allows the sub to handle more power than the typical shallow-mount sub.

Handles plenty of power
The SWR-T12 12" thin subwoofer handles up to 600 watts RMS for tremendous thump. Its aluminum woofer cone works with the multi-roll Santoprene™ surround for performance that will really surprise you. The finned aluminum heat sink is directly coupled to the frame for rapid heat dissipation that'll keep your sub running cool. Type-R Thin subs present ideal solutions for applications with limited available space, such as pickup trucks and compact cars.
