2x Alpine R2-W12D4 12" R-Series "R2" Subwoofer, Dual 4-Ohm, 750 Watt RMS - (R2-W12D4)
Alpine R2-W12D4 12" R-Series "R2" Subwoofer, Dual 4-Ohm, 750 Watt RMS
PRODUCT OVERVIEW
The next generation of sound performance is here with the new R-Series subwoofers featuring a larger motor structure for more accurate and authoritative bass.
New Motor Structure – The new R-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation.
Oversized Dust Cap – The new hybrid poly ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass.
Increased Accuracy – Alpine’s High Amplitude Multi-Roll (HAMR) Surround Technology allows the cone to efficiently move air while staying cool resulting in incredible accuracy from the subwoofer.
