Add authoritative low end to professional AV, security and monitoring systems with the QSC AD-S28TW-BK AcousticDesign surface mount subwoofer. Purpose-built for integrators, this pro subwoofer supplies tight, intelligible bass that reinforces paging, background music and surveillance audio without overpowering speech or camera audio feeds. The AD-S28TW-BK pairs with QSC AD Series loudspeakers and delivers 200W RMS handling and a high 94 dB sensitivity for efficient output from existing amplifiers. Its dual 8" polypropylene woofers and ported, weather-resistant enclosure produce controlled bass that extends into the mid-30s Hz range, while the built-in passive 120 Hz low-pass simplifies crossover setup for system installers. Surface-mount form factor and durable finishes make it ideal for retail, hospitality, transportation hubs, and security/monitoring rooms where reliable low-frequency performance is required.
