Bose Professional STS118E ShowTime 18-Inch High-Output Passive Installation Subwoofer
The STS118E is a passive, installation-grade 18-inch subwoofer that matches the scale and voicing of high-output Bose Professional loudspeaker systems. With extension down to 29 Hz, the STS118E provides the low-frequency impact required for music-forward and high-energy applications while remaining practical for permanent installations in both indoor and outdoor environments. The STS118E is optimized for ground-stacked placement and includes integrated suspension points, allowing system designers to adapt deployment based on room layout, sightlines, and architectural requirements. A universal pole cup supports both standard 35 mm poles and M20-threaded poles for temporary applications.
The IP55-rated construction enables deployment in exposed and semi-exposed locations across a wide range of venues. Finished in white, the ShowTime STS118E integrates cleanly into a variety of architectural environments while delivering long-term durability. When paired with compatible Bose Professional full-range loudspeakers, processors, and amplifiers, the subwoofer provides a reliable low-frequency foundation that supports high-output sound systems with consistency, durability, and predictable performance.
