    AcousticDesign surface loudspeakers offer a variety of models specifically taylored for demands of higher fidelity applications. Designed for clarity and presense, these loudspeaker systems deliver pristine audio reproduction for installations requiring a refined audio experience. Models ship complete with the award winning X-Mount system and weather input cover.

    Consistent and even conical coverage is achieved through Directivity Matched Transition (DMT), 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.

    AcousticDesign models with (T) suffix feature low-loss, low-saturation transformers with selectable taps, including an 8Ω bypass. To enhance weather resistance, the rotary selector is located on the back of the enclosure, protected by a weather grommet.

    To further enhance performance and speed of install with optimum result, advanced voicing filter sets using QSC Intrinsic Correction techniques are available via Q-SYS networked audio processing or CXD amplifier platforms for a complete QSC systems solution.
