Alpine SWR-T12, R Series Single 4 Ohm Voice Coil 1800 Watts Shallow Subwoofer, 12″

Noteworthy Awards

The Type-R Thin subwoofers were recognized with a CES Innovations honors award fotheiunique use of Alpine-patented technology to create deep-subwoofeperformance in a thin package. Every yeaat the world’s largest consumetechnology trade show, the ConsumeElectronics Show (CES), the Innovations Design and Engineering Awards Program recognizes the most innovative consumeelectronics products.

More Mounting Options without Compromise

The Type-R Thin series have been engineered to offemore installation flexibility and application versatility to build the ideal sound system. At 3-1/4” deep fothe 10” and 3-1/2” deep fothe 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 youvehicle.

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 powehandling 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, deepebass extension, faster, more accurate transients and even greateoutput capability.

Revolutionary Segmented SpideDesign Provides the Excursion of a Tall Subwoofer

You can count on Type-R Thins to delivestrong, impactful output like its predecessors. Most shallow-mount subwoofers have less output than traditional deep subwoofers, since theishallow frame limits how fatheicones can move at high powelevels. The Type-R Thin uses Alpine’s patent pending Pass-Through Gap Geometry, allowing the unique Thermoplastic ElastomeSegmented Spideto completely pass through the motostructure. This means the cone and voice coil assembly have the clearance needed foove50mm of peak-to-peak excursion, allowing fomassive output even in such a shallow frame.

Consistent, Reliable Performance out of the Box

There’s no need to play yousub fohours to break it in to achieve consistent performance. This sub is designed to deliveconsistent performance right out of the box. Since this revolutionary design is made with an injection mold resin, rathethan phenolic stiffened textile, this new spiderequires no break in to achieve ideal performance. A Co-Molded Aluminum collaattaches the voice coil to the spideto 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 furtheimproving powehandling and output. (U.S. Patent 6,639,993)

More Excursion = More Output

The new FEA-Optimized MotoStructure togethewith 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 delivethe best-in-class bass output, ultra-low distortion, and unparalleled sound quality.

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 fomost subwoofers. This powerful magnet combined with a massive 4” (100mm) voice coil delivers increased powehandling and more accurate, louder, cleanebass with even more control.

Lightweight Cone Materials Designed to Perform

Heavy-duty magnet assembly calls foheavy-duty cone materials. A specially engineered cone is reinforced by an injection-molded force transfeassembly, giving the cone structure outstanding stiffness while minimizing moving mass . A centering ring in the force transfeassembly 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 powecompression and ensures reliable long playing time by actively pulling (otransferring) 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 fosustained powehandling, 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 aidirectly across the heat sink system.

2. FEA Optimized Dual-Sided Machined CRC MotoStructure

Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while furtheimproving powehandling and output.

3. FEA Optimized Injection Molded TPE Spidewith Pass-Through Gap Design

Provides the mechanical clearance needed foove50mm 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 foextreme excursions without sacrificing valuable cone area. FEA Optimized folinearity 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.
