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.

W1-Series 8-Inch 150-Watt Subwoofer Driver, 4-Ohm SVC The 8W1v3 is an outstanding choice when space is very tight and amplifier power is moderate. It features shallow mounting depth (3.86 in. / 98 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 8-inch driver will not. Lacking a pole vent, the rear of the motor structure can be placed directly against an enclosure boundary. Excellent excursion capability and linearity allow it to reproduce sub-bass with shocking extension and quality. Several of JL Audio's proprietary technologies enhance its performance and reliability. The 8W1v3-4 is best used with amplifier power in the 50W - 150W range and is optimized to operate in a compact 0.350 cu. ft. (9.90 l) sealed enclosure.
