QSC strongly encourages you to use LS118, KS118 or KS212C subwoofer(s) together with LA108/LA112 loudspeakers. The determination of the subwoofer count depends on a number of factors including acoustics of the performance venue, whether it is indoors or outdoors, program content and sound pressure level expectations. A recommended starting point would be to use one subwoofer unit for every four (4) loudspeakers (two per side) you are using in your PA system.
