Product Research


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.

Customer Q&A

1 question already asked

we just got our AD-S8T speakers. The tap switch looks like it is set on 7.5W on the 70V side and 15W on the 100V side. Is that the settings?
