Product Description

Features & Specifications



Alpine R2-W10D2 R Series 10″ Subwoofer with Dual 2-ohm Voice Coils

The R2-W10D2 10″ sub capitalizes on this knowledge with a new motor structure with double-stacked magnets for deeper bass and tighter sound. Its Kevlar-reinforced pulp cone features a durable HAMR Santoprene™ surround that allows for huge amounts of excursion, and an oversized poly ceramic dust cap supplies rigidity to keep the sound tight. It’s the perfect sub for bassheads that want the best of both worlds: accurate response and otherworldly thump. With over 40 years of experience, Alpine has the know-how to deliver the kind of hard-hitting bass you want.

A versatile performer

The R2-W10D2 handles up to 750 watts RMS, so it’s ready for your high-powered amp. Its dual oversized 2-ohm voice coils allow you to draw maximum power from your mono amp. Since it works well in sealed or ported enclosures you’ll enjoy your music the way you like to hear it.

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.

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.

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 added protection to the cone. The R2-W10D2 is compatible with the KTE-10G Grille System (sold separately).

Increased accuracy

The 2nd-Gen R-Series Subwoofers contain 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.
