QSC AD-S402T-BK 60W, dB, 2.75" Column Surface-Mount Loudspeaker, Black

Deliver clear, reliable audio where intelligible voice and focused coverage matter most. The QSC AD-S402T column surface-mount loudspeaker is a premium 60W solution engineered for paging, public address, security and surveillance monitoring in acoustically challenging spaces. Its compact 2.75" column form uses four drivers and a PTT network to reduce side lobes and maintain consistent tonal balance, while the 70 V / 100 V transformer options and 16 Ω bypass give AV integrators flexible deployment across distributed PA or low‑impedance systems. Rated IP54 and built with a sealed enclosure, the AD-S402T stands up to dust and moisture for indoor/outdoor installations such as transit hubs, retail environments, campus security and perimeter monitoring. The pan/tilt quick-hang bracket keeps the speaker close to the wall and allows up to -20° downward tilt for precise coverage. Intrinsic Correction voicings via the Q-SYS ecosystem and UL1480A certification simplify tuning and compliance for emergency voice applications. Ideal for integrators specifying dependable voice reinforcement for security, surveillance and facility-wide announcements — contact sales or add the AD-S402T to your next system design.
