Noteworthy Awards

The Type-R Thin subwoofers were recognized with a CES Innovations honors award for their unique use of Alpine-patented technology to create deep-subwoofer performance in a thin package. Every year at the world’s largest consumer technology trade show, the Consumer Electronics Show (CES), the Innovations Design and Engineering Awards Program recognizes the most innovative consumer electronics products.

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.

FEA Optimized = Maximum Linearity

Alpine’s Patented Dual-Sided Compound Radius Curve pole geometry ensures an ultra symmetrical magnetic field with optimized flux density to greatly reduce distortion, while further improving power handling and output. (U.S. Patent #6,639,993)

More Excursion = More Output

The new FEA-Optimized Motor Structure together with the revolutionary High-Amplitude Multi- Roll (HAMR) Suspension Design gives the new Type-R Thin Subwoofers the highest X-max and SPL output in the category.

With a real-world, measured 15mm of X-max, allow the new Type-R Thin Subwoofers to deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality.

Maximize Performance with Power

Match the right amount of power for one or two Type-R thins?

More VC Control in a Smaller, Lightweight Package

Type-R Thin’s 1.5lb neodymium magnet has 5x the magnetic strength than standard ferrite magnets used for most subwoofers. This powerful magnet combined with a massive 4” (100mm) voice coil delivers increased power handling and more accurate, louder, cleaner bass with even more control.

Lightweight Cone Materials Designed to Perform

Heavy-duty magnet assembly calls for heavy-duty cone materials. A specially engineered cone is reinforced by an injection-molded force transfer assembly, giving the cone structure outstanding stiffness while minimizing moving mass . A centering ring in the force transfer assembly is also engineered to lock the voice coil assembly in place. This makes the entire piston assembly extremely strong and linear.

Keep it Cool = Keep it Playing

Alpine’s Patented Radial Vented VC Heat Sink and Airflow Management System (US Patent #7,634,101) helps to minimize power compression and ensures reliable long playing time by actively pulling (or transferring) output-robbing heat away from the Voice Coil

The new cast aluminum frame is directly coupled to the machined aluminum shorting sleeve assembly. This allows the entire frame to act as a heat sink for sustained power handling, even in the most extreme of applications.

4 Unique Alpine Technologies

1. Radial Vented VC Heat Sink & Airflow Management System- Actively manages voice coil temperatures by forcing air directly across the heat sink system.

2. FEA Optimized Dual-Sided Machined CRC Motor Structure - Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.

3. FEA Optimized Injection Molded TPE Spider with Pass-Through Gap Design - Provides the mechanical clearance needed for over 50mm of peak-to-peak excursion, unleashing massive output potential from a small package

4. FEA Optimized HAMR Surround - The High-Amplitude Multi Roll Surround Design allows for extreme excursions without sacrificing valuable cone area. FEA Optimized for linearity and made with injection-molded Santoprene ®, the HAMR surround is a key part of the suspension system that provides accurate, distortion-free control at extreme excursions.
