Description

ShowTime 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, STS118E provides the low-frequency impact required for music-forward and high-energy applications while remaining practical for permanent installations in indoor and outdoor environments. 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. IP55-rated construction enables deployment in exposed and semi-exposed locations across a wide range of venues. Available in black or white finishes, ShowTime STS118E integrates cleanly into a variety of architectural environments. When paired with compatible Bose Professional full-range loudspeakers, processors, and amplifiers, the subwoofer provides a reliable low-frequency foundation that supports high-output systems with consistency, durability, and predictable performance.
