The HK Audio LINEAR 9 118 Sub BA subwoofer is designed to meet the demands of professional audio environments requiring high sound pressure levels and a deep, penetrating bass. Featuring an 18″ driver with a 4″ voice coil housed in a generously-sized dual vented bandpass cabinet, this subwoofer achieves a low cut-off frequency while maintaining a peak SPL of 136 dB.

Integrated presets allow for easy setup of cardioid configurations, enhancing sound directionality and minimizing rear sound leakage. This unit is perfectly suited as a standalone subwoofer or as a complement to the LINEAR 9 118 Sub A, providing substantial low-frequency reinforcement for any live sound or installation setup.
