QSC / LS118 Powered Subwoofer

The QSC/LS118 is an 18-inch, 4000W active subwoofer.

Delivering an outstanding audio experience and outstanding performance with system intelligence and premium components, the LS118 was designed with a deep understanding of customer needs and application requirements. The LS118 can be easily configured and deployed in a wide range of applications, from simple and portable plug-and-play setups to advanced network-enabled AV production and fixed installations.

Featuring a QSC Acoustic Linear Phase (ALP) design, they can operate seamlessly and consistently with QSC loudspeakers within the same sound system. It also supports daisy-chaining of analog, network-compatible digital audio (DanteR), and AC power (PowerCON TRUE1). Furthermore, by configuring two or more LS118s in a cardioid configuration, you can maximize front low-frequency output while suppressing unnecessary energy to the sides and rear.

When combined with LA108 or LA112 active line array loudspeakers, they can be mounted in both horizontal and vertical orientation using array frame/ground stack adapters or speaker poles.
