The LS218 is a next-generation intelligent active subwoofer that combines cutting-edge technology, sophisticated engineering, and superior operability. It delivers high performance in an easy-to-install package.

System intelligence and high-quality components deliver superior performance and an exceptional audio experience. The LS218 was developed with a deep understanding of customer needs and real-world operating environments. It can be easily set up and deployed in a wide range of applications, from simple portable plug-and-play systems to advanced network AV systems and fixed installations.

It employs QSC's proprietary Acoustic Linear Phase (ALP) design, allowing for easy combination of QSC speakers within the same system while maintaining phase compatibility. It also supports daisy-chaining of analog audio, network digital audio (Dante?), and AC power (PowerCON TRUE1).

Using two or more LS218s allows for a cardioid configuration, maximizing low-frequency energy to the front of the system while suppressing unwanted low-frequency radiation to the sides and rear. When paired with the LA108 or LA112 active line array speakers, it supports both vertical and horizontal mounting using an array frame/ground stack adapter or speaker pole.
