QA118S is the companion subwoofer for QA108 passive two-way line array cabinets. The QA118S compact, high power subwoofer system is loaded with a B&CŪ custom made 18” woofer with a 4” voice coil in a bass-reflex designed cabinet  that is capable of handling 1200W at 4ohms. With an extended frequency response down to 36Hz, the QA118S delivers 132dB SPL. The cabinet is constructed with 13ply, 18mm (3/4”) Baltic birch plywood and is finished with a durable scratch and scuff resistant black paint. The cabinet also features integrated, ergonomically-placed carrying handles and a built-in top mount flange for an optional speaker mounting pole serving two-way satellite speakers. An optional four-wheel trolley (WT118S) with locking wheels is also available, allowing users to hold two QA118S subs in place for easy transportation, making them ideal for touring and mobile applications.
