New immersive sound surround formats place greater performance demands on surround loudspeakers in terms of frequency response, output capability, and mounting flexibility.

QSC’s AcousticPerformance Series loudspeakers meet these challenges with headroom to spare, especially for larger rooms. The uniform power-response of these loudspeakers is a result of Directivity Matched Transition (DMT™), a design approach that matches LF and HF coverage in the crossover region.

The AcousticPerfomance Series loudspeakers are a perfect match for DPA and DPA-Q Series power amplifiers for achieving the high-output, high-impact surround performance required by today’s immersive sound applications.

AcousticPerformance™ is a line of professional, loudspeakers, ideal for a variety of installed sound reinforcement applications requiring high power in a stylish enclosure. All models feature a 3-inch voice coil compression driver combined with high-output woofers to deliver exceptional full bandwidth reproduction.

The uniform power-response of AcousticPerformance loudspeakers is a result of Directivity Matched Transition (DMT™), a design approach that matches the compression driver to the natural coverage angle of the woofer in the cross-over region. Key to the extraordinary accuracy and flat power response of the AcousticPerformance line are the axisymmetric waveguides which help deliver remarkably consistent coverage with smooth and accurate reproduction both on and off-axis.

AcousticPerformance™ models may be used in passive (full-range) mode to minimize amplifier channel count or bi-amp mode for greater control and performance. To further enhance performance, bi-amp and full-range tunings using QSC Intrinsic Correction techniques are available for Q-SYS™ and future QSC products.

All models feature M10 mounting points for deployment via eye-bolts as well as mount points for an optional yoke bracket. 

To further present a professional, clean and unobtrusive look, AcousticPerformance grilles are unadorned; eliminating the need to cover-up logo treatments which can be difficult to hide or remove. The grille is also lined with acoustically transparent backing, adding to the enclosure’s professional appearance.


To minimize impact and disposal fees at the job site, all AcousticPerformance loudspeakers are packaged in environmentally friendly, recyclable cartons.
