QSC PL-CA6 – Two-Way Passive 6-in Coaxial Loudspeaker, Black

Product Overview

The QSC PL-CA6-BK is a two-way full-range 6-inch coaxial installation loudspeaker designed for distributed and foreground coverage where point source imaging and extended bandwidth are required. With 115° conical DMT coverage and a trapezoidal enclosure, this passive coaxial loudspeaker delivers consistent on- and off-axis response from a compact cabinet. The black (RAL 9011) Baltic plywood enclosure carries IP54 weatherization with polyurea paint for installed indoor and covered outdoor use. It is a purpose-built solution for surface-mount distributed and fill audio in fixed-install systems.

Product Description

The PL-CA6 combines a 6-inch LF transducer with a coaxial compression-driver HF section to deliver a system bandwidth of 77 Hz to 20 kHz (−3 dB) with point source coherence. The 115° conical DMT coverage provides wide, symmetrical dispersion suited to overhead and wall-mounted distribution. System sensitivity is 93 dB (1 W/1 m), with continuous SPL of 111 dB and peak SPL of 123 dB. Power handling is 215 W continuous and 430 W program at 8 Ω. The cabinet connects via a single locking 4-pole 14 AWG Euroblock in an IP65-sealed input cup. Rigging uses 4x M6 top/bottom patterns and a single M8 for the PL-CA6-YM yoke mount. The 60° trapezoidal Baltic plywood enclosure is available in black or white; this model ships in black. Polyurea paint, an IP54 rating, and an IP65 input cup support installed environments. At 13.4 lbs, it balances output and bandwidth with a compact, mountable form factor.
