The LS218 is a next-generation, intelligent, active subwoofer featuring a brilliant combination of leading-edge innovation, refined engineering, and unparalleled ease of use in an easy-to-deploy package.

Delivering extraordinary audio experiences and exceptional performance via system intelligence and premium components, the LS218 is the result of a deep understanding of customer needs and application requirements. The LS218 is easy to configure and deploy for applications ranging from simple, portable, plug-and-play setups to demanding, networked, high-tech AV productions and fixed installations.

Featuring QSC Acoustic Linear Phase (ALP) design, which permits effortless combination and coherent deployment of QSC loudspeakers within the same sound system, the LS218 also provides daisy-chain connections for analog, networked digital audio (Dante®), and AC power (PowerCON TRUE1). Two or more LS218s can be configured in a cardioid arrangement, maximizing low-frequency output in front while minimizing unwanted energy around the sides and rear of the system.

Together with the LA108 or LA112 active line array loudspeakers, the LS218 can be deployed with either an array frame/ground-stack adapter or using loudspeaker poles in both horizontal and vertical orientations.
