Alpine

R-Series 8-Inch 350-Watt Subwoofer Driver, 2-Ohm or 4-Ohm Dual Voice Coil Since the Type R platform, Alpine’s R-Series sound system family has been known for its incredible output and reliable performance. Now Alpine introduces the next-generation of sound performance with the 2nd-Gen R-Series Subwoofers with even more bass output. The 2nd-Gen R-Series Subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control from the subwoofer cone compared to the previous generation. An integrated Faraday ring minimizes distortion for cleaner bass output. A Kevlar-treated cone ensures durability in the subwoofer for reliable performance, even at high volumes. A new polypropylene/ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass. This premium, unique material also has higher heat reliability that ensures non- stop bass performance. The 2nd-Gen R-Series Subwoofers contain a Dual Voice Coil (DVC) with easy configuration jumpers that allow for flexible applications. A new “EZ- Change” twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone. The R2-W8D2 and R2-W8D4 is compatible with the KTE-8G Grille System (sold separately). The 2nd-Gen R-Series Subwoofers contain Alpine’s High Amplitude Multi- Roll (HAMR) Surround Technology. This rubber surround allows the subwoofer cone to efficiently move air while staying cool. This technology allows for 20mm of total cone excursion and motion that creates incredible accuracy from the subwoofer.

Alpine 350-Watt 10-Inch Truck Subwoofer Enclosure, 2Ω Final Impedance With a compact wedge-style design and shallow mount, the SBT-S10V (2-ohm system) is a perfect fit for truck applications, with a design that works in small spaces. Radial Vented VC Heat Sink & Airflow Management System actively manages voice coil temperatures by forcing air directly across the heat sink system. FEA Optimized Dual-Sided Machined CRC Motor Structure creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output. 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 provides accurate, distortion-free control at extreme excursions. Specifications 2Ω Impedance Ported Enclosure Design Frequency Response: 28Hz-200Hz Dimensions 21-5/8" Wide x 15-1/4" Tall x 7-1/4" Deep 1x 3-15/16" Alpine SBT-S10V Manual

Alpine 350-Watt Thin 10-Inch Subwoofer Driver, 2Ω or 4Ω Impedance The 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. The FEA-Optimized Motor Structure together with Alpine's 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 TECHNOLOGIES Radial Vented VC Heat Sink & Airflow Management SystemActively manages voice coil temperatures by forcing air directly across the heat sink system.
