Alpine, SWR-8D2

Extreme bass fits in more places

The Type-R Subs have been completely redesigned to offer more installation flexibility and application versatility to build the ideal sound system. At 115 mm of mounting depth for the 8” (20 cm) this new design offers 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 12 mm of X-max, allow the new 8” (20cm) 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.
