QSC PL-DC12 – 12-in 2-Way Passive/Bi-Amp Directivity Control Loudspeaker, Black

Product Overview

The QSC PL-DC12-BK is a two-way passive 12-inch directivity control point source loudspeaker engineered for high-output main coverage with reconfigurable dispersion in demanding fixed installs. With rotatable half-horn assemblies offering multiple symmetrical and asymmetrical patterns, this passive directivity control loudspeaker tailors its coverage to large-venue geometry. 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 primary reinforcement in auditoriums, houses of worship, and large multi-purpose venues.

Product Description

The PL-DC12 pairs a 12-inch neodymium LF transducer with a 3-inch voice coil and a 1.4-inch exit compression driver with a 3-inch voice coil to deliver a system bandwidth of 50 Hz to 20 kHz (-3 dB) from a 30 degree trapezoidal enclosure. The reconfigurable and rotatable half-horn assemblies provide symmetrical 90x50 degree (default), 70x50 degree, or 110x50 degree coverage, plus asymmetrical 100, 90, and 80 degree splits. System sensitivity ranges from 101 to 103 dB depending on horn configuration, with continuous SPL of 119 to 121 dB passive and 121 to 123 dB bi-amped. Power handling is 450 W continuous and 900 W program at 8 ohm. The cabinet supports passive operation at a 1.1 kHz crossover or bi-amp operation at 1 kHz. Connectivity includes two Speakon NL4 connectors and a parallel locking 4-pole Euroblock in an IP65-sealed input cup. Rigging uses 3x M10 on top and bottom, 2x M10 on the sides, and 4x M6 patterns for the PL-DC12-YM yoke mount and M10 KIT. IP54 weatherization with polyurea paint and an IP65 input cup supports challenging fixed-install environments. At 46.8 lbs, it delivers high-SPL full-range output with flexible pattern control.

Key Features

• Reconfigurable Coverage — Rotatable half-horn assemblies provide 90, 70, or 110 degree symmetrical and multiple asymmetrical patterns.
• 12-Inch Neodymium LF — 3-inch voice coil driver delivers extended low-frequency reach down to 50 Hz (-3 dB).
• High SPL Output — Up to 121 dB continuous passive and 123 dB bi-amped for large-venue reinforcement.
• Passive or Bi-Amp Operation — Selectable crossover at 1.1 kHz passive or 1 kHz bi-amp adapts to system architecture.
• Asymmetrical Horn Options — Multiple split patterns target non-symmetrical seating from a single cabinet.
• M10 Rigging — Multiple M10 and M6 points with M10 KIT and PL-DC12-YM yoke support flexible mounting.
• IP54 Weatherization — Polyurea paint and IP65 input cup support covered outdoor installation.

Typical Applications

• Auditorium — primary high-SPL coverage with pattern control matched to deep seating.
• House of worship — full-range music and speech reinforcement for large sanctuaries.
• Multi-purpose room — high-output adaptable coverage for concerts and assemblies.
• Commercial meeting space — reinforcement for large all-hands and event venues.
• Government space — installed coverage for large council chambers and assembly halls.
