Dual 4Ω

R-Series 12-Inch 750-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-W12D2 and R2-W12D4 is compatible with the KTE-12G 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.

TW3-Series 12-Inch 400-Watt Thin Subwoofer Driver, 4-Ohm or 8-Ohm DVC The 12" TW3 thin subwoofer driver by JL Audio offers a shallow mounting depth with an excursion capability that is remarkably capable of greater excursion than JL's W3v3 full size subwoofers. JL Audio’s TW3 sub utilizes a patented thin-line woofer technology that compresses the architecture of the 12TW3 woofer using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and spider, while allowing the placement of the large motor structure to be moved further forward on the chassis than with conventional designs. JL Audio 12TW3-D4 and 12TW4-D8 are optimized for small enclosures and offers JL's tab-ear mounting design to maximize cone area within their mounting footprints. Deep, powerful and accurate JL Audio bass is now possible in more applications than ever. Very shallow mounting depth (3.25 / 3.50 Inches) No pole vent: permits mounting close to rear wall of enclosure. Very small sealed enclosure volume requirements Very long linear excursion capability (0.60 In / 15.2 mm, one-way) DMA-optimized motor designs “concentric tube” architecture Patented “floating cone attach method” technology Cast alloy frame Injection molded, mica-filled polypropylene cone Rubber surround Aluminum-alloy dust cap and rear cap with JL Audio logo Precision-built in USA at JL Audio’s Miramar, Florida factory with global components General Specifications Continuous Power Handling 400W RMS Recommended Amplifier Power 200W - 400W RMS Nominal Impedance Dual 4Ω/8Ω JL Audio 12TW3 Manual
