They deliver deep, clean, accurate bass and feature Alpine’s HAMR Surround for maximum cone excursion, delivering tons of bass output. the new ceramic dust cap is very lightweight and rigid, keeping distortion to an absolute minimum.

The new, enlarged motor structure ensures better overall woofer control for clean, strong bass response.

New Motor Structure

The 2nd-Gen R-Series Subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control from the subwoofer cone compared to the previous generation. An integrated Faraday ring minimises distortion for cleaner bass output. A Kevlar-treated cone ensures durability in the subwoofer for reliable performance, even at high volumes.

Next-Gen Sound Performance

Since the Type R platform, Alpine’s R-Series sound system family has been known for its incredible output and reliable performance. Now Alpine introduces the next-generation of sound performance with the 2nd-Gen R-Series Subwoofers with even more bass output.

Additional Reliability

A new polypropylene/ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass. This premium, unique material also has higher heat reliability that ensures non-stop bass performance.

Flexible Application

The 2nd-Gen R-Series Subwoofers contain a Dual Voice Coil (DVC) with easy configuration jumpers that allow for flexible applications. A new “EZ-Change” twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for additional protection to the cone.

Increased Accuracy

These subwoofers feature Alpine’s High Amplitude Multi-Roll (HAMR) Surround technology. This rubber surround allows the subwoofer cone to efficiently move air while staying cool. This technology allows for 20mm of total cone excursion and motion that creates incredible accuracy from the subwoofer.

Sizes & Variations

The new R-Series subwoofers are available in 12”, 10” and 8” size configurations and come in dual 2Ω and dual 4Ω impedances.
