Features

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-S4T is a surface mounted 70/100V, 4.5" two-way loudspeaker system, ideally suited for a wide variety of foreground and background sound reinforcement applications.

Note: The AD-S4T is sold in pairs.

Two-Way Driver Design: The AD-S4T features a high quality 4.5" weather treated paper cone woofer on a 1" voice coil. A carefully selected horn-loaded 0.75" silk dome tweeter with 0.75" voice coil perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction.

DMT (Directivity Matched Transition): Consistent and even 120° 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-S4T is aided by a 30-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.

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.
