10-Inch 750-Watt Alpine R-Series Halo Loaded Subwoofer Enclosure with ProLink Connectivity 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.   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.
