The Type-R Thin Subwoofers have been designed to deliver greater installation flexibility. At only 89mm deep, this sub provides deep bass performance where traditional subwoofers just can't fit.

This Sub Encompasses many of the great new Alpine technologies. These innovative technologies allow the Type-R Thin Subwoofer to have the output and power handling of the traditional Type-R series in less that half the depth. The design of Alpine's Pass-Through Gap Geometry, allows the Thermoplastic Elastomer Segmented Spider to entirely 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 enormous output dispite such a shallow frame. The all-new FEA Optimised motor structure and HAMR surround supply the new Type-R Thin subwoofers the highest X-max and SPL output in their class.
