QSC LA108-KIT-SA Array Frame Stack Adapter Kit for LA108 Line Array Loudspeakers

The QSC LA108 stack adapter kit expands the L Class ecosystem by enabling safe, repeatable ground stack deployment of LA108 line array modules on QSC subwoofers. Designed to be used with the LA108-AF array frame, the kit couples the fly bar to an LS118 subwoofer or KS118 to create a stable base for compact line array stacks. Once installed, the adapter provides indexed ground-tilt positions—tilt angles of 6°, 0°, ?6°, and ?12°—so you can aim coverage predictably without improvising spacers or shims. That means faster setups, cleaner sightlines, and more consistent results for mobile portable PA rigs, rentals, and fixed installs that can’t fly an array.

This kit is purpose-built for LA108 system owners who need the flexibility to fly or stack from the same array frame. It integrates mechanically with the LA108-AF; no third-party brackets or drilling are required. In typical use, engineers stack up to four LA108 modules on a single LS118 (or KS118) and fine-tune the downward angle to hit the audience plane while keeping energy off the stage and walls. Because the adapter is official rigging hardware from QSC, it aligns with L Class documentation, aiming workflows, and best practices, reducing guesswork for teams that rotate between flown and ground-stacked deployments.

Compatibility is straightforward: use the LA108-KIT-SA with LA108 loudspeakers, the LA108-AF array frame (required), and an LS118 or KS118 subwoofer platform. The included hardware attaches directly to the array frame; no modification to the loudspeakers or subwoofers is needed. For planning, QSC’s tools and documentation outline the allowed stack sizes and tilt selections, helping you stay within recommended configurations while achieving even coverage. Whether you’re building a compact touring rig, augmenting a house-of-worship system, or adding modular options to a production inventory, this L Class adapter kit keeps your LA108 family versatile, fast, and future-ready.
