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.

Deeper Bass Output

The enclosures come preloaded with the 2nd-Gen R-Series Subwoofers with 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.

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, which also contributes to increased output from the subwoofers. This technology allows for 20mm of total cone excursion and motion that creates incredible accuracy from the subwoofer.
