Qsc LS218

Exceptional performance.
The LS218 is a next-generation smart active subwoofer that combines cutting-edge innovation, sophisticated engineering, and ease of use.

It is easy to configure and deploy for a variety of applications, ranging from simple plug-and-play setups to demanding networked audiovisual productions, as well as fixed installations.


QSC Acoustic Linear Phase (ALP) Design.
Featuring QSC’s Acoustic Linear Phase design, which enables effortless integration and consistent deployment of QSC loudspeakers within a single sound system, the LS218 also offers daisy-chain connections for analog audio, networked digital audio (Dante®), and AC power (PowerCON TRUE1). Two or more LS218 subwoofers can be configured in a cardioid array, maximizing low-frequency output toward the front while minimizing unwanted energy to the sides and rear of the system.

Optimal integration with LA108 or LA112 loudspeakers.
When paired with LA108 or LA112 active line array loudspeakers, the LS218 can be deployed either with a bumper and adapter kit for ground stacking, using a connection mast in a horizontal or vertical orientation, or suspended using M10 lifting eyes.



For a balanced sound experience, we recommend a ratio of three (3) LA112s or four (4) LA108s to one (1) LS218 subwoofer.




The LS218 is covered by a 6-year warranty when registered within 30 days of purchase.
