Overview:
Audio professionals looking for a next-generation intelligent subwoofer will be impressed with the QSC LS 118, an active subwoofer that's designed to complement the LA 108 and LA 112 line array loudspeakers, featuring a brilliant combination of cutting-edge innovation, refined engineering, and unparalleled ease of use in an easy-to-deploy package, well suited for live venues, fixed installations, mobile entertainers, AV rental, and event production.
The LS 118 utilizes a 3600W Class-D amplifier module, which powers the 18" woofer for a frequency response of 41 to 98 Hz with a max SPL of 136 dB. The rear panel features a 2.4" full-color display with a rotary push-button for setting up speaker configurations and fine-tuning the sound. The two 3-pin XLR connectors, powerCON True 1 I/O connectors, and two RJ45 etherCON network I/O connectors are Dante and QSC SysNav compatible. The LA 118 includes a powerCON TRUE 1 power cord.
