QSC PL-CA8 – Two-Way Passive/Bi-Amp 8-in Coaxial Loudspeaker, Black

Product Overview

The QSC PL-CA8-BK is a two-way full-range 8-inch coaxial installation loudspeaker built for higher-output distributed and foreground coverage where point source imaging and full-range program are required. With 110° conical DMT coverage and a trapezoidal enclosure, this passive coaxial loudspeaker delivers consistent on- and off-axis response with bi-amp capability. The black 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 main fill audio in fixed-install systems.

Product Description

The PL-CA8 combines an 8-inch neodymium LF transducer with a coaxial compression-driver HF section to deliver a system bandwidth of 73 Hz to 20 kHz (−3 dB) with point source coherence. The 110° conical DMT coverage provides wide, symmetrical dispersion suited to overhead and wall-mounted distribution. System sensitivity is 97 dB (1 W/1 m), with continuous SPL of 115 dB passive and 116 dB bi-amped. Power handling is 230 W continuous and 460 W program at 8 Ω, with separate LF and HF ratings supporting bi-amp operation. Connectivity includes two Speakon NL4 connectors and a parallel locking 4-pole Euroblock in an IP65-sealed input cup. Rigging uses 4x M6 patterns, 2x M10, and a single M8 for the PL-CA8-YM yoke mount, plus 2x M10 on the sides. The 57° trapezoidal 15 mm Baltic plywood enclosure, polyurea paint, IP54 rating, and IP65 input cup support installed environments. At 24 lbs, it delivers higher SPL with point source coherence in a mountable cabinet.

Technical Specifications

Frequently Asked Questions

Does the PL-CA8 support bi-amping?

Yes. It provides separate LF and HF power ratings and dual Speakon connectors for both passive and bi-amp operation.

What is conical DMT coverage?

It refers to QSC's Directivity Matched Transition coaxial design, which maintains a consistent 110° conical pattern across the crossover region.

What mounting accessory is available?

The PL-CA8-YM yoke mount attaches via the cabinet's M6, M10, and M8 rigging points.

Can it be used outdoors?

Yes, in covered locations. It carries IP54 weatherization with Baltic exterior plywood, polyurea paint, and an IP65 sealed input cup.

What connectors are provided?

Two Speakon NL4 connectors and one parallel locking 4-pole Euroblock in an IP65 sealed input cup.

What amplifier power is recommended?

The loudspeaker is rated for 230 W continuous and 460 W program at 8 Ω.
