QSC Triple LA108 + LS118 Ground Stack Line Array System

Product Overview

This QSC ground-stack line array system combines six LA108 active 8-inch line array loudspeakers with two LS118 powered 18-inch subwoofers for scalable, full-range coverage. Array frames and stack adapters let three LA108 modules per side ground-stack on the subwoofers for larger audiences. Self-powered modules with onboard DSP and QSC Intrinsic Correction deliver consistent throw and tonal balance without external amplification. It ships as a complete kit with array frames, stack adapters, and jumper kits.

Product Description

Six LA108 active line array boxes (1,300W each) and two LS118 subwoofers (4,000W each) form a stereo ground-stacked system suited to mid-size live events. The included LA108 array frames and stack adapter kits set array splay and couple the boxes to the subwoofers, while three North American jumper kits handle interconnection. Compare or expand with the standalone QSC LA108 and QSC LS118 subwoofer.
