QSC PL-DC24 – Dual 4-in 2-Way Passive Directivity Control Loudspeaker, Black

Product Overview

The QSC PL-DC24-BK is a two-way passive dual-4-inch directivity control point source loudspeaker designed for stage fills, delays, and under-balcony fill where a compact horizontal profile is required. With a fixed 110° x 50° horn and an asymmetrical enclosure profile, this passive directivity control loudspeaker delivers consistent coverage from a low-visibility cabinet. The black (RAL 9011) exterior-plywood enclosure carries IP54 weatherization with polyurea paint for installed indoor and covered outdoor use. It is a purpose-built solution for distributed fill and supplemental coverage in fixed-install systems.

Product Description

The PL-DC24 pairs dual 4-inch neodymium LF transducers in a V-shaped layout with a 0.7-inch exit compression driver to deliver a system bandwidth of 119 Hz to 20 kHz (−3 dB). System sensitivity is 97.5 dB (1 W/1 m), with continuous SPL of 111 dB and peak SPL of 123 dB. The fixed-horn point source design provides 110° x 50° coverage, and the asymmetrical 15° profile between top and bottom supports horizontal orientation for stage-lip and fill applications. Power handling is 120 W continuous and 240 W program at 8 Ω. The cabinet connects via a single locking 4-pole 14 AWG Euroblock in an IP65-sealed input cup. Rigging options include rear, top/bottom, and side M8 points for the PL-DC24-YM yoke mount or PL-DC24-FM flush mount. Weatherization features exterior plywood, stainless screws, a UV-treated grille, hydrophobic mesh, polyurea paint, and an IP65 input cup with cable gland. At 8.7 lbs, it installs in tight locations with minimal hardware load.
