2 Soundstream R3.8 Reference R3 8" Dual 2-Ohm Subwoofer Sometimes a woofer comes along that changes the game. The R3 is just that; it has a high roll surround for an extended excursion. With a 4-Layer voice coil and a gigantic motor structure, it can handle some serious authority. This woofer can get down and hang with just about any other woofer out there with incomparable sound quality. Whether an SPL competitor or an SQ competitor, this is a woofer that can do it all.Reference R3 Woofers use fiberglass stranding woven together for ultimate strength and less elasticity.

2 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. 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.
