R2-W12D4Next-Generation 12-inch R-Series Subwoofer with Dual 4-Ohm Voice CoilsThe next generation of sound performance is here with the 2nd-Gen R-Series Subwoofers featuring a larger motor structure for more accurate and authoritative bass.FEATURES Duel Voice Coil (DVC) Subwoofers with Configuration Jumpers Polypropylene/Ceramic Composite Dust Cap Kevlar Reinforced Pulp Cone High-Performance subwoofers Twist-Lock Grille Mount System High-Amplitude Multi-Roll (H.A.M.R.) Surround Large Double-Stacked Magnets What’s in the Box: 12” R2-Series DVC Subwoofer with Cosmetic Trim Ring 2 Jumper Wires for DVC Configuration Owner’s Manual SPECIFICATIONS 750W RMS 2250W Peak Power Handling Frequency Response: 24Hz-200Hz Sensitivity (1W/1m): 84.5dB Nominal Impedance: 4Ω Voice Coil: 65mm X-Max: 20mm Magnet Weight: 144oz Mounting Depth: 6-1/2” (152mm) Cutout Size: 10-7/8” (231mm) Push-Type Speaker Terminals (Up to 8AWG Wire Size) CTA-2031 Compliant NEXT-GEN SOUND PERFORMANCESince 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.NEW MOTOR STRUCTUREThe 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.ADDITIONAL RELIABILITY 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. FLEXIBLE APPLICATION 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-W12D4 is compatible with the KTE-12G grille system (sold separately). INCREASED ACCURACY 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.
