The PS18S Parasource 18-inch powered subwoofer is the largest and most powerful model in Yorkville's Parasource series, built to deliver authoritative low-frequency performance for professional PA systems. Featuring a high-output 18-inch woofer with a 4-inch voice coil and a high-efficiency Class D amplifier, it delivers up to 1200 watts program power with impressive clarity and control.
Engineered as the ideal low-end companion for the PS15P powered loudspeaker, the PS18S provides tight, impactful bass that enhances live music, DJ playback, and installed sound applications. Flexible XLR and 1/4 inch TRS inputs with link outputs allow easy system integration, while support for line or speaker-level signals adds setup versatility.
Housed in a rugged 15 mm birch cabinet with all-metal handles and an integrated pole mount adapter, the PS18S is built for durability, portability, and reliable performance in small to medium venues.
