Alpine SWR-12D2 12 Inch Subwoofer
These redesigned fifth-generation Type-R Alpine SWR-12D2 12 inch 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.
Extreme bass fits in more places
The Type-R Alpine Subwoofers have been completely redesigned again to offer more installation flexibility and application versatility to build the ideal sound system. At 4-1/2″ for the 8″, 5 – 7/8” for the 10”, and 6 – 3/8” for the 12”, these new designs offer a near 20% reduction in mounting depth, while offering even greater output capability.
More Excursion = More Output
The new FEA-Optimized 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 21mm of X-max, allow the new Type-R Subwoofers to deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality.
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 black anodized 65 mm voice coil offers more than 35% more surface area, allowing for increased power handling to 1000W RMS / 3000W Peak. To get the best performance, we recommend you pair Type-R subs with Alpine’s new PDX digital amplifiers.
