QSC PL-CA12 – Two-Way Passive/Bi-Amp 12-in Coaxial Loudspeaker, Black

Product Overview

The QSC PL-CA12-BK is a two-way full-range 12-inch coaxial installation loudspeaker engineered for high-output, long-throw point source coverage with extended low-frequency reach. With 80° conical DMT coverage and a trapezoidal enclosure, this passive coaxial loudspeaker delivers coherent imaging and high SPL for main and fill applications in larger venues. The black Baltic plywood enclosure carries IP54 weatherization with polyurea paint for installed indoor and covered outdoor use, and supports flown sub-satellite systems with the PL-SUB15. It is a purpose-built solution for primary coaxial reinforcement in fixed-install systems.

Product Description

The PL-CA12 combines a 12-inch neodymium LF transducer with a 3-inch voice coil and a coaxial 3-inch voice coil compression driver to deliver a system bandwidth of 47 Hz to 20 kHz (−3 dB) with point source coherence. The 80° conical DMT coverage provides controlled, long-throw dispersion suited to deeper rooms. System sensitivity is 102 dB (1 W/1 m), with continuous SPL of 119 dB passive and 120.5 dB bi-amped. Power handling is 330 W continuous and 660 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, 3x M10, and a single M8 for the PL-CA12-YM yoke mount, with additional M10 points on the sides and rear; the PL-CA12-SL suspension link pairs with the PL-SUB15 for flown sub-satellite configurations. The 53° trapezoidal 15 mm Baltic plywood enclosure, polyurea paint, IP54 rating, and IP65 input cup support installed environments. At 44 lbs, it delivers high-SPL full-range coaxial output.

Key Features

• Coaxial Point Source — 12-inch neodymium LF and coaxial 3-inch compression HF deliver coherent imaging from a single axis.
• 80° Conical DMT Coverage — Controlled, long-throw dispersion for deeper rooms and main coverage.
• Extended Low-Frequency Reach — Response down to 47 Hz (−3 dB) supports full-range music program.
• Passive or Bi-Amp Operation — Separate LF and HF ratings support both passive and bi-amp deployment.
• Flown Sub-Satellite — PL-CA12-SL suspension link pairs with PL-SUB15 for integrated low-end arrays.

Technical Specifications

Frequently Asked Questions

Can the PL-CA12 be flown with a subwoofer?

Yes. The PL-CA12-SL suspension link pairs the cabinet with the PL-SUB15 for flown sub-satellite configurations.

Does it 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 80° conical pattern across the crossover region.

What mounting accessory is available?

The PL-CA12-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 amplifier power is recommended?

The loudspeaker is rated for 330 W continuous and 660 W program at 8 Ω.
