Alpine - Next Generation S-Series 8" Dual-Voice Coil 4-Ohm Subwoofer - Black

The new design and enhanced performance of the R2-Series subwoofers offer deeper bass and tighter bass control compared to the previous generation. Updates to the new generation include larger, double-stacked magnets, an integrated Faraday ring, and a Kevlar-treated cone. All of these updates equal unmatched durability and reliable performance, even at high volumes. The R2-W8D2 handles up to 350 watts RMS. Its dual oversized 2-ohm voice coils allow you to draw maximum power from your mono amp. Since it works well in sealed or ported enclosures you'll enjoy your music the way you like to hear it.

Engineered To Fit And Sound Great In Your TruckThis SWT Truck Subwoofer combines the intense low-bass performance and ground-shaking output of the traditional Type-R subwoofers in a thin package optimized for extremely small enclosures.Shallow Mounting DepthThe SWT 10” Truck Subwoofer has been engineered to offer more installation flexibility without sacrificing big output to build the ideal sound system for your truck. At 4-1/8” deep, these subs provide deep bass performance where it normally couldn’t fit in a truck. And the vented pole optimized for 4-1/8” deep box is the ideal enclosure size meaning great bass performance can fit just about anywhere in your truck.More Excursion = More OutputThe FEA-Optimized Motor Structure together with our revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives the new SWT Truck Subwoofers the highest X-max and SPL output in its category.The new SWT Truck Subwoofers deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality. With a real world, measured 11mm of X-max, the SWT subwoofers perform like traditional models, yet fit in smaller spaces.4 Unique Alpine TechnologiesRadial Vented VC Heat Sink & Airflow Management SystemActively manages voice coil temperatures by forcing air directly across the heat sink system.FEA Optimized Dual-Sided Machined CRC Motor StructureCreates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.FEA Optimized Injection Molded TPE Spider with Pass-Through Gap DesignProvides the mechanical clearance needed for over 50mm of peak-to-peak excursion, unleashing massive output potential from a small packageFEA Optimized HAMR Surround

The CompR 8” Subwoofer is a 2-Ohm dual voice coil design, making it easy to get the most out of your amp. Our signature red double stitching makes an outstanding bond between the improved Santoprene surround and polypropylene woofer cone. Revolutionary SoloKon technology joins the cone to the vented back brace, creating a single integrated until that both cools the motor and eliminates distortion. To make our subs even more reliable KICKER engineers developed Forced Air Cooling to help our subs run 25% cooler than before.
