The PS18SF Parasource 18-inch flyable powered subwoofer is engineered to deliver massive, precise low-frequency performance for both portable and installed PA systems. Featuring a high-output 18-inch woofer with a 4-inch voice coil and a high-efficiency Class D amplifier, it produces up to 1200 watts program power and delivers clean, impactful bass with minimal distortion.
Built with integrated fly points, the PS18SF allows safe suspension in theaters, clubs, houses of worship, and other venues requiring flown or mounted subwoofers. Flexible XLR and 1/4 inch TRS inputs with link outputs accept line or speaker-level signals, making integration with full-range loudspeakers like the PS15P seamless and effortless.
Housed in a rugged 15 mm birch cabinet with durable metal handles and a reinforced steel grille, the PS18SF combines professional performance, portability, and installation versatility. Ideal for live bands, DJs, and fixed installations, it provides authoritative low-end reinforcement without taking up valuable floor space.
