The New 2022 R-Series Subwoofers
The next generation of sound performance is here with the 2nd-Gen R-Series Subwoofers featuring a larger motor structure for more accurate and authoritative bass.

Alpine’s new 2nd generation R-Series Subwoofers feature enhanced sound performance in an exciting new aesthetic. With a larger motor structure featuring double-stacked neodymium magnets and an integrated faraday-ring results in a deeper, cleaner and tighter bass while the all-new Kevlar-treated cone ensures this extra performance is reliable – even at higher volumes.

The new EZ-Change twist-lock grille mounting system makes subwoofer installation easier than ever-before. The optional grille (KTE-12G), exudes a tough look with the benefit of added protection.

Quality and Performance unrivalled in the industry, Alpine’s new 2nd Generation R-Series continues to be the benchmark in sound quality for the audio enthusiast.


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 minimizes 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.

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