Alpine KTX-LK10 10-Inch PrismaLink™ Enclosure Linking Bracket Kit
Product overview:
The Alpine KTX-LK10 is a specialized hardware expansion kit designed to seamlessly connect multiple 10-inch Alpine PrismaLink™ S2-SB10 subwoofer enclosures. Whether you want to step up to a dual-sub setup or create a massive "bass wall" with three or four enclosures, this kit provides the structural integrity and aesthetic finish needed for a professional multi-sub installation.
Features
Seamless Connectivity
The KTX-LK10 is engineered for unlimited multi-link capability. It allows you to mechanically join two or more S2-SB10 enclosures together so they function as a single, rigid unit. This modular design gives you the flexibility to start with one subwoofer and "stack" your system over time as your bass needs grow, without ever needing to replace your existing boxes.
Safety & Convenience
Constructed from heavy-duty steel, the kit includes both front and rear link bracing to ensure your enclosures stay perfectly aligned and securely fastened. It is a comprehensive "bolt-on" solution that includes all necessary mounting hardware. By anchoring the boxes together, you eliminate the safety hazard of individual enclosures sliding or tipping in your cargo area during spirited driving.
Effortless Lighting Expansion
One of the standout features of the KTX-LK10 is the included RGB wiring harness. This allows you to extend the integrated RGB lighting trim bars from one PrismaLink™ enclosure to the next effortlessly. The front bracket also features a silver trim design that matches the PrismaLink™ aesthetic, ensuring that the visual "glow" and hardware finish remain consistent across your entire subwoofer array.
Fine Tune Your Sound
By linking multiple 10-inch enclosures, you can tailor your sound setup precisely. Doubling or tripling the number of subs increases the total cone surface area, allowing for significantly higher sound pressure levels (SPL) and deeper low-frequency extension. Because the brackets are precision-cut for the S2-SB10, they maintain the perfect spacing for the side-firing ports, ensuring your audio performance is never compromised by the physical connection.
