                                  2 Alpine R2-W10D4 10" R-Series next generation 4 Ohm 2250 Max, 750W RMS DVC Car Audio Subwoofer + KTE-10G.3 Grills Alpine R2-W10D4 2250W Max (750W RMS) 10" R-Series Dual 4-Ohm Car Subwoofer The new R-Series subwoofers take a great platform to the next level. Although the R-Series subwoofers are new for 2017, they come from an impressive Alpine lineage – the Type-R subwoofers. Type-R subwoofers have been known for their power handling, clean output, and deep bass excursion at a mid-line price. Using the highly successful Type-R subwoofers as a foundation, we applied various performance and hardware improvements to the design, fundamentally transforming them into the new R-Series subwoofers – The Next Evolution of Proven Performance. STRONGER CONE ASSEMBLYR-Series subwoofers feature a Kevlar-treated cone for durability. This cone and the Santoprene surround allow the subwoofer to deliver 19mm X-max for incredible, hard-hitting bass. A new method of attaching the spider and cone to the voice coil ensures rigidity throughout the motor structure and increases the subwoofer's accuracy. MORE RIGID DUST CAP Talc, a common mineral used in products such as baby powder and paint, has been found to have incredible damping properties while being less dense than the traditional Mica filler used in dust caps. By adding a calculated amount of talc to the mica polypropylene in the dust cap, we increased the cap's vibration absorption while lowering its density. The lighter dust cap contributes to a faster attack and a more accurate reproduction of low frequencies. NEW POWER RATING All four R-Series subwoofers are rated at 750W RMS. They perfectly match the PDR-M65 Mono Power Density Amplifier, creating an efficient system. General Features: 10" Dual 4 ohm Type-R Subwoofer Peak Power Handling: 2250 watts RMS Power Handling: 750 watts Recommended power range: 300 - 750W RMS CTA-2031 compliant power ratings Parabolic pulp/kevlar cone H.A.M.R. surround Polypropylene, mica, and talc dust cap Reinforced cone neck and spider joint Cast aluminum frame with integral shorting sleeve 8AWG push terminals with VC configuration jumpers 2.6" High excursion overhung voice coil 111 oz.

Alpine S-W10D2 1800W Max (600W RMS) 10" S-Series Dual 2 Ohm Car Subwoofer with Absolute VGS10 Ported Subwoofer Box Alpine introduces the all-new S-Series Subwoofers; their unique design substantially improves bass output and provides installation versatility. Each S-Series subwoofer uses a custom-stamped steel frame and is available in twelve, ten, and eight-inch. These high-strength frames were designed to withstand the rigors of the improved S-Series motor. They have frame leg vents, a vented back plate to help cool the subwoofer voice coil and motor parts, and a shallow design to help fit in smaller spaces. The S-Series Subwoofers incorporate two strontium ferrite magnets stacked together, providing increased motor strength and excursion, ultimately delivering an accurate bass to your music. The convenient push-type insert terminals with a dual voice coil jumper system will significantly reduce installation time. Just strip the speaker insulation at the wire end, then insert the bare wire into the hole of the spring-loaded push terminal. At the same time, the concealed mount gasket system creates a clean, finished appearance for any vehicle.
