Combining a 15-inch neodymium LF driver with a coaxially mounted compression driver in a trapezoidal bass-reflex enclosure, the PL-CA15 delivers coherent 80° conical coverage using QSC's Directivity Matched Transition (DMT) technology — ensuring consistent frequency response across the coverage pattern from low frequencies through high frequencies.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe PL-CA15 enclosure is constructed from 15 mm Baltic exterior plywood with a durable polyurea paint finish and an IP54 environmental rating, making it suitable for challenging installation environments. The coaxial driver arrangement places the HF compression driver at the acoustical center of the 15-inch LF cone, achieving a unified wavefront that eliminates the time alignment and comb filtering artifacts associated with traditional point-source two-way designs. The system operates passively with an 8-ohm nominal impedance, or in bi-amp mode using separate LF and HF amplifier channels for increased headroom and control. The IP65-rated input cup accepts dual Speakon NL4 connectors and a 4-pole Euroblock for flexible wiring. Extensive rigging provisions — including top\/bottom M6 pattern points, three M10 attachment points, M8 yoke attachment, two M10 side points, and two M10 rear pullback anchors — support a wide range of flown and ground-stacked configurations. The PL-CA15-YM yoke mount (sold separately) enables precise pan and tilt positioning.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e15-inch neodymium LF driver

different from a standard two-way loudspeaker?\u003c\/dt\u003e\n\u003cdd\u003eIn a coaxial design, the HF compression driver is mounted at the acoustical center of the LF woofer cone, so both drivers share the same point of origin. This eliminates the time alignment and off-axis comb filtering issues common in traditional two-way designs, producing more consistent coverage across the full frequency range.\u003c\/dd\u003e\n\u003cdt\u003eWhat is Directivity Matched Transition (DMT)?\u003c\/dt\u003e\n\u003cdd\u003eDMT is QSC's technology that matches the directivity pattern of the LF driver to the HF driver at the crossover frequency, resulting in a smooth, uniform 80° coverage pattern from low frequencies through high frequencies without hot spots or pattern narrowing at crossover.\u003c\/dd\u003e\n\u003cdt\u003eCan the PL-CA15-BK be used in bi-amp mode?\u003c\/dt\u003e\n\u003cdd\u003eYes. The PL-CA15 supports both passive (single amplifier channel) and bi-amp (separate LF and HF channels) operation. Bi-amp mode increases continuous SPL by 2 dB and peak SPL by 2 dB compared to passive mode.\u003c\/dd\u003e\n\u003cdt\u003eIs a yoke mount available for the PL-CA15-BK?\u003c\/dt\u003e\n\u003cdd\u003eYes.
