PowerWorks ZETHUS-112BPW
The PowerWorks ZETHUS 112BPW is a powered, two-way 12-inch compact line array loudspeaker designed for medium-to-large live sound reinforcement, touring productions, houses of worship, and multi-cabinet flying installations. Engineered to serve as the core mid/high vocal and acoustic projection module in the modular ZETHUS line array family, it features integrated precision-machined aluminum rigging hardware that allows rapid splay-angle adjustments when flown in curved arrays or ground-stacked atop companion subwoofers (such as the ZETHUS VX118SPW). Driven by a high-efficiency Class-D bi-amplified engine with integrated DSP, the 112BPW delivers defined speech intelligibility, wide horizontal sound coverage, and high SPL capability.
Core Performance Features
-
Integrated Line Array Rigging System: Features heavy-duty aluminum side rigging frames, quick-release locking ball pins, and multi-angle splay brackets (typically $0^\circ$ to $10^\circ$ increments) for precise acoustic array curving and safe flying or ground-stacking.
-
Class-D Bi-Amplified Engine: High-efficiency, lightweight Class-D power module independently powers the 12-inch low/mid transducer and titanium high-frequency compression driver, ensuring high dynamic headroom and low operating temperatures.
-
Cylindrical Wavefront Horn Loading: Equipped with a specialized waveguide coupled to the HF driver, producing a coherent, low-distortion planar wavefront that minimizes inter-cabinet phase cancellation and extends high-frequency throw.
-
Broad Horizontal Dispersion: Features a wide horizontal dispersion pattern (typically $90^\circ$ to $100^\circ$) to provide consistent, wall-to-wall audience coverage while tightly controlling vertical dispersion to prevent ceiling and floor reflections.
-
Onboard Digital Signal Processing (DSP): Provides factory acoustic array presets (varying HF shading and EQ curves depending on the number of arrayed boxes), active crossover filtering, and multi-stage peak/RMS limiters.
-
Tour-Grade Wooden Enclosure: Built from multi-ply void-free Baltic birch/hardwood plywood coated with an abrasion-resistant, water-resistant textured polyurea black finish, fronted by a heavy-gauge powder-coated steel grille.
-
Pro Power & Signal Looping: Fitted with balanced XLR line inputs and thru/loop connections alongside locking power connector in/out terminals, enabling streamlined cable management and power daisy-chaining across flown clusters.
