The QSC AP-5122 Loudspeaker is a result of DMT (Directivity Matched Transition), a design approach that matches LF and HF coverage in the cross-over region. The AP-5122 uses a high power-capacity, 76mm (3-inch) diaphragm compression driver and combines it with a 305mm (12-inch) woofer to deliver exceptional full bandwidth reproduction.

The uniform power-response of the AP- 5122 loudspeaker is a result of DMT (Directivity Matched Transition), a design approach that matches LF and HF coverage in the cross-over region. Another key to the extraordinary accuracy and flat power response of the AP-5122 is the axisymetric waveguide with uncompromised performance in both the vertical and horizontal axes. The result is remarkably consistent coverage and smooth, accurate reproduction on and off-axis.

The AP-5122 may be used as a passive (full-range) loudspeaker to minimize amplifier channel count or it may be bi-amplified 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.
