PRODUCT FEATURES

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 efciently move air while staying cool resulting

in incredible accuracy from the subwoofer.
