PROEL S18 A Active Professional Subwoofer – 18 Inch
The PROEL S18 A marries compact dimensions with uncompromising low-frequency authority. Its Hybrid Band-Pass architecture. Driven by a muscular 1200 W peak Class-D amplifier, produces tight, punchy bass down to 36 Hz. Meanwhile, keeping distortion remarkably low, even at a thunderous 131 dB SPL.
Hybrid Band-Pass Powerhouse
Firstly, the innovative HBP cabinet couples the 18-inch high-excursion woofer to precisely tuned ducts, delivering greater acoustic efficiency than conventional direct-radiating designs. The result is deeper, louder bass with reduced port turbulence and cleaner transients.
Smart Connectivity & Control
Dual Neutrik combo inputs accept both XLR and ¼-inch signals, while dedicated XLR link and filtered outputs simplify system expansion. Also, a selectable 24 dB/octave crossover and phase reverse switch ensure seamless integration with any full-range top cabinet.
Road-Ready Construction
Built from rugged 15/18 mm plywood and armored in polyurethane paint, the S18 A is designed to thrive on the road. Furthermore, flush side handles, an M20 pole socket and four smooth-rolling 75 mm wheels make load-ins effortless without sacrificing structural integrity.
