QSC PL-DC8 – 8-in 2-Way Passive/Bi-Amp Directivity Control Loudspeaker, White

Product Overview

The QSC PL-DC8-WH is a two-way passive 8-inch directivity control point source loudspeaker finished in white (RAL 9003) for installs requiring reconfigurable coverage and a low-visibility cabinet. With rotatable half-horn assemblies offering symmetrical and asymmetrical patterns, this passive directivity control loudspeaker adapts its dispersion to room geometry while blending with light architectural surfaces. The exterior-plywood enclosure carries IP54 weatherization with polyurea paint for installed indoor and covered outdoor use. It is a purpose-built solution for main and fill coverage in fixed-install reinforcement systems.

Product Description

The PL-DC8 pairs an 8-inch neodymium LF transducer with a 2-inch voice coil and a 1-inch exit compression driver to deliver a system bandwidth of 61 Hz to 20 kHz (−3 dB) from an 11° trapezoidal enclosure. The reconfigurable and rotatable half-horn assemblies provide symmetrical 120° x 50° (default), 90° x 50°, or asymmetrical 105° (60°+45°) x 50° coverage. System sensitivity is 99 dB (120° x 50°) or 100 dB (90° x 50°), with continuous SPL up to 114 dB passive and 116 dB bi-amped. Power handling is 260 W continuous and 520 W program at 8 Ω. The cabinet supports passive operation at a 1.6 kHz crossover or bi-amp operation at 1.5 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-DC8-YM yoke mount and M10 KIT. The white RAL 9003 finish, IP54 weatherization, polyurea paint, and IP65 input cup support challenging fixed-install environments where aesthetics matter. At 26.7 lbs, it delivers full-range output with flexible pattern control.

Key Features

• White RAL 9003 Finish — Light-toned enclosure blends with ceilings and pale architectural surfaces.
• Reconfigurable Coverage — Rotatable half-horn assemblies provide 120°, 90°, or asymmetrical 105° horizontal patterns.
• 8-Inch Neodymium LF — Single driver with 2-inch voice coil delivers extended low-frequency reach down to 61 Hz (−3 dB).
• Asymmetrical Horn Option — 60°+45° split coverage targets non-symmetrical seating from a single cabinet.
• Passive or Bi-Amp Operation — Selectable crossover at 1.6 kHz passive or 1.5 kHz bi-amp adapts to system architecture.
• Trapezoidal Enclosure — 11° cabinet geometry supports tight array clustering and corner placement.
• IP54 Weatherization — Polyurea paint and IP65 input cup support covered outdoor installation.

Typical Applications

• House of worship — full-range reconfigurable coverage that blends with light sanctuary finishes.
• Auditorium — main or fill coverage with pattern control tuned to the audience plane.
• Multi-purpose room — adaptable dispersion with extended low-end for music and speech.
• Commercial meeting space — high-output reinforcement for presentations and program audio.
• Government space — installed coverage for council chambers and assembly halls.

Technical Specifications

Frequently Asked Questions

How does the PL-DC8-WH differ from the PL-DC8-BK?

The specifications are identical; only the enclosure finish differs, with the WH model supplied in white RAL 9003.

How is the coverage pattern changed?

The PL-DC8 uses reconfigurable and rotatable half-horn assemblies to select 120°, 90°, or asymmetrical 105° (60°+45°) horizontal coverage.

Does it support bi-amping?

Yes. It operates passively at a 1.6 kHz crossover or bi-amped at 1.5 kHz.

What rigging hardware is available?

The cabinet provides M10 and M6 points and is compatible with the PL-DC8-YM yoke mount and M10 KIT.

Can it be installed outdoors?

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

What amplifier power is recommended?

The system is rated for 260 W continuous and 520 W program at 8 Ω.
