2-way, surface-mounted commercial 8" speaker (Black)
Our take on the QSC AD-S8T by Crutchfield's Eric Angevine
Big sound for your distributed audio system
If you have a big space that needs plenty of bass, the QSC AD-S8T is your go-to speaker. This speaker features a hard-hitting 8" woofer and a 1" compression-driver tweeter that produces sizzling highs.
AD-S8T speakers are weather-resistant, so you can use them for music and live paging of customers indoors or out. QSC includes a sturdy and highly adjustable X-mount assembly that allows you to mount and aim this large speaker easily and safely. The speaker also features multi-tap transformers for use with 70-volt or 100-volt audio systems, and 8-ohm nominal impedance allows plenty of power distribution options as well.

AcousticDesign Series: QSC's AcousticDesign series offers integrators a premium quality installed sound solution where performance, coverage, and aesthetics are paramount. Combined with unprecedented ease-of-installation and high weather resistance, the AcousticDesign series provides integrators a versatile and confident install solution.
Surface Mount Speaker: The QSC AcousticDesign AD-S8T is a surface mounted 70/100V, 8" two-way loudspeaker system, ideally suited for a wide variety of foreground and background sound reinforcement applications.
Two-Way Driver Design: The AD-S8T features a high quality 8" weather treated paper cone woofer on a 2" voice coil. A carefully selected 1" exit, 1.4" compression driver perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction.
DMT (Directivity Matched Transition): Consistent and even 105° axisymmetric (conical) coverage is achieved through DMT (Directivity Matched Transition), a QSC innovation which matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point. The result is a coherent transition between transducers and improved off-axis response.
70/100V or 8-Ohm: The even, accurate frequency response of the AD-S8T is aided by a 60-watt low-loss, low-saturation transformer with selectable taps, including an 8Ω bypass. To preserve weather resistance, the rotary selector is located on the back of the enclosure, protected by a weather grommet.
Euro-Style Connector: The Euro-style connector allows pre-wiring of the speaker and when combined with the quick "snap-on" deployment of the loudspeaker to the mount, installation is completed in a fraction of the time required versus competitive models.
Rugged Enclosure Rated for Indoor & Outdoor Use: With rugged ABS enclosures, sealed input panel covers, and powder-coated aluminum grilles for weather resistance, the AcousticDesign surface mounted series exceed IEC60529 IP-54 ratings for dust and splash resistance. The AD Series loudspeakers qualified for outdoor use using the following tests.
- Salt Fog: MIL-STD-810G Method 509.5 for 100 hrs.
- Humidity: MIL-STD-810G Method 507.5, Natural cycle B2, cyclic high RH for 7 days.
- High & Low Temperature: Tested to QSC internal standards between -20° and 50° C.
X-Mount System: Installers will appreciate the award-winning X-Mount system included with each full-range AcousticDesign model. This ingenious mounting solution achieves unprecedented ease-of-installation in horizontal, vertical, wall, or ceiling deployments. Knurled surfaces at the pivot planes ensure the load will not drift or sag over time. Articulation marks allow pre-configuration of the X-Mount while on the ground with no special tools required. Once secure, the loudspeaker installs in seconds, allowing the installer to work safer, smarter, and faster.
Note: The AD-S8T also includes M10 fittings for optional yoke mount (YMS8T) or shoulder eyebolt (M10 Kit-C) accessories for installation versatility.
Black or White Finish + Paintable: The AcousticDesign series feature a stylish appearance free of obtrusive logo adornments for aesthetically sensitive installations. AcousticDesign surface loudspeakers are available in QSC standard black or white, and may be painted to match any decor.
