QSC PL-DC8 – 8-Inch 2-Way Passive Installation Loudspeaker with Directivity Control

Product Overview

The QSC PL-DC8 is an 8-inch two-way passive point-source loudspeaker with directivity control from QSC's PL Series of installation loudspeakers. Its reconfigurable, rotatable half-horn assemblies let integrators select symmetrical 120° x 50° or 90° x 50° patterns, or an asymmetrical 105° x 50° pattern, for precise control over where sound lands. Built for the Q-SYS ecosystem, the PL-DC8 is driven by CX-Q Series network amplifiers for custom voicings, protection, and telemetry. Its weatherized IP54 plywood enclosure supports indoor and protected outdoor installations as a front-of-house, delay, or distributed loudspeaker.

Product Description

The PL-DC8 pairs an 8-inch LF driver and HF compression driver in a trapezoidal bass-reflex cabinet with an 11° box angle for array building. Its standout feature is the field-reconfigurable horn: installers can rotate and mix the half-horn sections to tailor symmetrical or asymmetrical coverage to the room, reducing reflections and overspill. Top and bottom M10 points plus M6 hole patterns support a range of mounting positions, and the optional PL-DC8-YM yoke mount adds wall and structure mounting. The passive design presents an 8-ohm load. For full-range systems, add low-frequency support and compare the larger-format QSC PL-DC12 point-source loudspeaker.
