The Bose ShowTime STS118E is engineered for system integrators and AV designers specifying permanent, high-output installed sound systems in demanding venues. With a single 18-inch high-excursion woofer and low-frequency extension reaching 29 Hz, this passive subwoofer is built to anchor music-forward systems in performance venues, houses of worship, sports facilities, themed entertainment environments, and outdoor gathering spaces where consistent, full-range impact is required night after night.
Unlike consumer or portable subwoofers, the STS118E is designed from the ground up for fixed installation. Its exterior-grade birch plywood enclosure, powder-coated perforated stainless steel grille, and IP55-rated construction make it suitable for semi-exposed and direct-exposure outdoor deployments without additional weatherproofing. Four stainless-steel M10 suspension points allow it to be flown when architectural sightlines demand it, while the enclosure is equally optimized for ground-stacked placement — giving system designers genuine deployment flexibility on a single SKU.
The universal pole cup accepts both standard 35 mm and M20-threaded poles, supporting full-range loudspeaker mounting in temporary or hybrid configurations. When integrated with Bose Professional AMU, AMM, or Forum full-range systems, processors, and amplifiers, the STS118E delivers a predictable, scalable low-frequency foundation designed to match the voicing and headroom of the broader Bose Professional ecosystem.
