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.
