Universal Car Stereo Rearfire Vented Sealed Single 12" Alpine R2-W12D4 Type R Car Audio Subwoofer Custom Sub Box Enclosure Package This Package Includes the Following Items: 1 x Absolute VEGS12 Car Audio Single 12" Sealed Subwoofer Sub Box Enclosure MDF Wood 1 x Alpine R2-W12D4 Car Audio Type S Series Sub Dual 4 Ohm 1200W Peak 12" Subwoofer Alpine R2-W12D4 2250W Max (750W RMS) 12" 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. The combination of this cone with the Santoprene surround allows the subwoofer to deliver 19mm of 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 vibration absorption of the cap while lowering the 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. These subwoofers perfectly match the PDR-M65 Mono Power Density Amplifier to create a system that works efficiently together. General Features: 12" Dual 4 ohm Type-R Subwoofer Peak Power Handling: 2250watts 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 127 oz.
