PowerWorks ZETHUS-VX118SPW

Core Performance Features

• Tour-Grade Line Array Integration: Outfitted with integrated heavy-duty aluminum side hardware, quick-release locking ball pins, and multiple angle-adjustment points, allowing seamless mechanical flying or ground-stacking with compatible ZETHUS series line array top cabinets.

• High-Efficiency Class-D Power Engine: Houses a cool-running, lightweight Class-D power amplifier module engineered to deliver sustained low-frequency transients, large dynamic headroom, and low thermal dissipation during long, high-SPL concerts.

• 18-Inch Long-Excursion Transducer: Built around a custom-engineered 18" low-frequency woofer featuring a high-temperature 4-inch (100 mm) copper voice coil and massive vented magnet assembly to prevent power compression during prolonged maximum-output operation.

• Onboard Digital Signal Processing (DSP): Provides adjustable crossover points (typically selectable between 80 Hz, 100 Hz, and 120 Hz), phase reversal switching ($0^\circ / 180^\circ$), and multiband peak/RMS dynamic limiters to safeguard the transducer against mechanical over-excursion.

• Heavy-Duty Birch Plywood Enclosure: Constructed from multi-ply void-free Baltic birch plywood, coated with an abrasion-resistant, rugged polyurea textured touring finish and fitted with an acoustic foam-backed, powder-coated steel grille.

• Pole-Mount & Stacking Flexibility: Features a heavy-duty threaded M20 pole-mount plate on top for supporting satellite full-range speakers on distance rods, as well as molded top feet alignment cups for stable multi-cabinet ground stacking.

• Professional Signal & Power Connectivity: Equipped with balanced XLR input and link connectors, as well as locking PowerCON (or equivalent power connector) in/thru loop connections for clean, secure stage power distribution.
