Alpine SWR-8D2, R Series Dual 2 Ohm Voice Coil 1000 Watts Subwoofer, 8″

Extreme bass fits in more places

The Type-R Subs have been completely redesigned again to offemore installation flexibility and application versatility to build the ideal sound system. At 4-1/2″ fothe 8″, 5 – 7/8” fothe 10”, and 6 – 3/8” fothe 12”, these new designs offea nea20% reduction in mounting depth, while offering even greateoutput capability.

More Excursion = More Output

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

More MotoForce = More Control

Starting with a new ten piece, segmented magnet structure, the new Type-R subwoofehas ove20% more motoforce than its predecessodelivering more accurate, loudeand cleanebass 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 powecompression 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 fosustained poweoutput and handling, even in the most extreme of applications.

FEA Optimized = Maximum Linearity

Alpine’s Patented Compound Radius Curve pole geometry ensure foan ultra symmetrical magnetic field, while optimizing flux density to greatly reduce distortion, while furtheimproving powehandling and output.

Improved PoweHandling

The oversized black anodized 40 mm voice coil offers more than 35% more surface area, allowing foincreased powehandling to 350W RMS / 1000W Peak. To get the best performance, we recommend you paiType-R subs with Alpine’s new PDX digital amplifiers.

4 Unique Alpine Technologies 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 allows foextreme excursions with accurate, distortion-free control.

FEA Optimized Spidew/reinforced LayeSpideIntegration

Ensures reliable and consistent control of the tinsel-leads to eliminate any possible mechanical noises ointerference typical of many high-excursion designs.

Redial Vented VC Heat Sink & Airflow Management System

Actively manages voice coil temperatures by forcing aidirectly across the heatsink system.

FEA Optimized Machined CRC MotoStructure

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