QSC AD-S6 – AcousticDesign 6.5-Inch 2-Way IP54 Surface-Mount Loudspeaker (Pair, Black)

Product Overview

The QSC AD-S6 is a 6.5-inch, 16-ohm passive two-way surface-mount loudspeaker sold as a pair for premium commercial sound reinforcement. Part of QSC's AcousticDesign Series, it suits restaurants, retail, education, transportation terminals, and houses of worship where coverage, performance, and aesthetics matter.

Unlike its transformer-equipped AD-S6T sibling, the AD-S6 is a 16-ohm low-impedance design intended for high-fidelity distributed systems without a line transformer, paired with a separately available amplifier of about 300W per pair.

Product Description

Each AD-S6 combines a 6.5-inch weather-treated paper-cone woofer (1.5-inch voice coil) with a waveguide-coupled 1-inch silk-dome tweeter, delivering a 58 Hz to 20 kHz frequency range, 89 dB sensitivity, and a 116 dB peak SPL. DMT (Directivity Matched Transition) provides smooth 105° conical coverage with uniform response across the listening area.

The sealed ABS enclosure, powder-coated aluminum grille, and sealed input panel cover meet IEC60529 IP-54 for dust and splash resistance, supporting indoor or covered outdoor use across an operating range of -4 to 122°F. A 4-pin Euroblock input with thru-output simplifies daisy-chained wiring.

The included X-Mount system installs the loudspeaker in seconds at repeatable angles with no long-term sag, and QSC Intrinsic Correction voicings are available through Q-SYS or CXD amplifier platforms. Integrators needing a 70/100V transformer version in the same form factor can specify the QSC AD-S6T.

Frequently Asked Questions

Why is the AD-S6 16-ohm and not 70/100V?
The AD-S6 is a low-impedance design for high-fidelity distributed systems where a transformer is not required. If you need 70V/100V distributed operation, choose the transformer-equipped QSC AD-S6T.

What amplifier power is recommended?
QSC recommends approximately 300 W of amplifier power per speaker, with 150 W RMS / 300 W program power handling.

Is it rated for outdoor use?
Yes, it meets IEC60529 IP-54 for dust and splash resistance, suitable for covered or semi-exposed outdoor commercial environments.

What warranty and support come with this loudspeaker?
QSC installed loudspeakers are covered under QSC's standard limited warranty; refer to QSC's published warranty terms for the current coverage period applicable to this model. Creation Networks provides pre- and post-sale support for system design and integration questions.
