Alpine Electronics Introduces Next-Gen Alpine Halo R-Series Preloaded Subwoofer Enclosures

The subwoofers feature Alpine’s next-generation R-Series Subwoofers

AUBURN HILLS, Mich. (Jan. 07, 2022) – Alpine Electronics of America, Inc. introduces the next-generation Alpine Halo R2-Series Preloaded Subwoofer Enclosures with ProLink™. The enclosures come preloaded with Alpine’s new 10” and 12” R2-Series subwoofers that feature an all-new design to offer cleaner, more controlled bass response.

“Alpine believes in the constant pursuit of better sound,” said Mike Anderson, Vice President and General Manager, Brand Business Unit, Alpine Electronics of America, Inc. “Adding the next-gen R2-Series subwoofers to our Alpine Halo enclosures is just one step towards getting the most premium sound experience in the vehicle.

Deeper Bass Output

Since its introduction, Alpine’s R-Series sound system family has been known for incredible output and outstanding performance. Today Alpine introduces the next-generation of sound performance with the new R2-Series subwoofers, featured in the Alpine Halo R2-Series Preloaded Subwoofer Enclosures with ProLink™.

These next-generation R2-Series Subwoofers feature larger, double-stacked magnets, which results in an increase of 5%-8% more motor strength in the subwoofer compared to the previous generation. This increase in motor strength produces a wider frequency band in the subwoofer, which will in turn play deeper bass with more authority. The new R2 design also delivers improved control over the moving subwoofer cone for tighter, cleaner bass response.

Additional design improvements to the subwoofers include a new ceramic composite dust cap that is lightweight, yet rigid and provides incredible internal damping (vibration absorption) to smooth out the frequency response and reproduce tight bass. This premium, unique material also has a higher heat capacity that contributes to the non-stop bass performance customers have come to expect from Alpine’s R-Series system.

The new R2-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, which also contributes to increased output from the subwoofers.

The new design and enhanced performance of the next-generation R2-Series subwoofers results in a cleaner, more controlled bass response from the Alpine Halo R2-Series Preloaded Subwoofer Enclosures with ProLink™. The ported enclosures feature an optimized vent and rounded internal port edges that maximize the output performance of the subwoofer, for deeper, reliable bass. Each enclosure is also wired for optimized performance with Alpine’s R-Series R-A75M Mono Power Amplifier.

Unique ProLink® Technology

Traditionally, single and dual subwoofer enclosures are sold as independent systems, leaving no room for flexibility when it comes to sound system building. If a single subwoofer enclosure was originally purchased, the only option for adding more bass to the system was to remove the single subwoofer enclosure and purchase a new, dual subwoofer enclosure.

Alpine’s unique ProLink™ technology was designed with the sound system builder in mind. ProLink™ allows more flexibility in both power and price to start with a single subwoofer enclosure and add an additional subwoofer using a Linking Kit (sold separately) to link two enclosures together to create a dual system when more bass is desired.

Groundbreaking Alpine Halo Design

The Alpine Halo R2-Series Preloaded Subwoofer Enclosures with ProLink™ share the premium, unmistakable design of the Alpine Halo Family. The enclosures pull design cues from the Alpine Halo Display with unique, curved edges outlined by a silver trim and a front baffle for a matching system aesthetic. Built with sturdy, 3/4” MDF construction and covered in a premium black carpet, these enclosures give the impression of a custom look, without the custom work.

The R2-SB12V and R2-SB10V will ship in January 2022 at a MAP of $449.95 and $429.95 respectively.

The next-generation R2-Series Subwoofers featured in the Alpine Halo R2-Series Preloaded Subwoofer Enclosures with ProLink™ will also be available as separate components in an 8” option for $219.95 (R2-W8D4, R2-W8D2) 10” for $299.95 (R2-W10D4, R2-W10D2), and 12” for $349.95 (R2-W12D4, R2-W12D2).
