Key Features

8" (20cm) TypeR Subwoofers - Alpine SWR8D2

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.

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 38 mm voice coil allows for increased power handling of 350W RMS / 1000W 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.

  • Question: 18 August 2016
    Car: Skoda Octavia - 2005 >

    I have PDX-F4, 2 x SPR-60C on channels 1 and 2. Looking to bridge 3 and 4 to drive 8 inch subwoofer. Your SWR8D2 would seem too much load.Am I mistaken?

    Answer: 
    Good afternoon
    The alpine SWR8D2 is fine.It is a dual 2 ohm woofer which you can wire in series to achieve a 4 ohm load which is perfect for that amp.
