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. ALPINE HALO DESIGN The enclosures 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. 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. 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 a higher heat reliability that ensures non-stop bass performance. 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. OPTIMIZED SOUND PERFORMANCE 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.
