ALPINE SWR12 D2/D4 – 12 Type-R Subwoofers (2 + 2 )/(4 + 4 ) These redesigned fifth-generation Type-R subwoofers include an abundance of enhanced features to achieve staggering power handing capabilities, cleaner output, deeper bass extension and ultra-responsive control than ever before.
Maximum bass output Alpine’s Type-R subwoofers will bring big bass to just about any vehicle. The SWR-12D2 12′ sub features a cone made from Kevlar treated pulp the same material used to make bulletproof vests and its durable HAMR Santoprene surround allows for huge amounts of excursion. This sub was built for bassheads that want the best of both worlds: accurate response and otherworldly thump.

Bring on the power The SWR-12D2 can handle an astounding 1000 watts of RMS power, so be sure to choose a suitable amplifier as these bass monsters definitely want lots of power. Its dual oversized 2-ohm voice coils offer the wiring flexibility you’ll appreciate as your system changes and grows, so you can always pull maximum power from your amp. It works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.
Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.
Highlights: 12′ subwoofer with dual 2-ohm voice coils Kevlar reinforced pulp cone with HAMRS Santoprene rubber surround frequency response: 24-200 Hz power handling: 300-1,000 watts RMS (500 watts per coil) peak power: 3,000 watts sensitivity: 84.7 dB top-mount depth: 6-3/8′ sealed box volume: 0.75-1.00 cu. ft. ported box volume: 1.25-1.50 cu. ft. warranty: 1 year Our 60-day money-back guarantee Extreme bass fits in more places The Type-R Subs have been designed to offer more installation flexibility and application versatility to build the ideal sound system. At 149 mm for the 10 (25 cm) and 162 mm for the 12 (30 cm), these new designs offer even greater output capability.
More Excursion = More Output The new FEA-Optomized Motor Structure together with our revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives the new Type-R Subwoofers the highest X-max and SPL output in the category.
With a real-world, measured 21 mm of X-max, allow the new Type-R Subwoofers to deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality.
More Motor Force = More Control
Starting with a new ten piece, segmented magnet structure, the new Type-R subwoofers deliver more accurate, louder and cleaner bass with even more control. This new magnet assembly is also an integral part of the next generation of Alpine’s Patented Radial Vented VC cooling system.
Keep it Cool = Keep it Playing Alpine’s Patented Radial Vented VC Heatsink and Airflow Management System (US Patent 7,634,101) helps to minimize power compression and ensures reliable long playing time by actively eliminating output-robbing heat away from the Voice Coil. The new one-piece cast aluminum frame with integrated shorting sleeve uses the entire frame as a heatsink, to allow for sustained power output and handling, even in the most extreme of applications.
FEA Optimized = Maximum Linearity Alpine’s Patented Compound Radius Curve pole geometry ensure for an ultra symmetrical magnetic field, while optimizing flux density to greatly reduce distortion, while further improving power handling and output.
Improved Power Handling The oversized 65 mm voice coil offers more than 35% more surface area, allowing for increased power handling to 600W RMS / 1800W Peak. To get the best performance, we recommend you pair Type-R subs with Alpine’s new PDX digital amplifiers.
4 Unique Alpine Technologies
1. 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 allows for extreme excursions with accurate, distortion-free control.
2. FEA Optimized Spider w/reinforced Layer Spider Integration Ensures reliable and consistent control of the tinsel-leads to eliminate any possible mechanical noises or interference typical of many high-excursion designs.
3. Redial Vented VC Heat Sink & Airflow Management System Actively manages voice coil temperatures by forcing air directly across the heatsink system.
4. FEA Optimized Machined CRC Motor Structure Creates a symmetrical magnetic field while optimizing flux density to greatly reduce distortion, while further improving power handling and output.
