QSC AD-S5T AcousticDesign 5.25 inch Surface-Mount Loudspeaker
The AD-S5T is the small end of the AcousticDesign surface-mount family, pairing a 5.25 inch paper cone woofer with a 1 inch damped fabric dome tweeter behind a wide 115 degree conical DMT pattern. That coverage is what makes it useful in low-ceiling rooms, corridors and restaurant seating where speakers sit close to the listener and even coverage matters more than throw.
It carries a transformer with 70 V taps at 7.5, 15, 30 and 60 watts plus bypass to 8 ohms, so it drops into a distributed line or runs low impedance from a small amplifier. Input is on a Euroblock connector with parallel output terminals for looping the next box in the run, and the enclosure is offered in black or white.
