Description
The Yorkville PSA18S is a high-performance subwoofer designed to deliver powerful, extended low-frequency reinforcement for the Paraline compact line array series. Featuring 3000 watts of peak power and an 18” neodymium woofer with a 4” voice coil, it produces deep, authoritative bass that perfectly complements PSA28 full-range enclosures, while remaining versatile enough to pair with a wide range of top boxes. Its IP54-rated construction ensures dependable operation in both indoor and outdoor environments.
Designed for flexible deployment, the PSA18S supports ground-stack or flown configurations with integrated rigging hardware and included eyebolts for safe suspension. A 35 mm (1 3/8”) stand adapter allows it to be used as a stable base with the Yorkville SW-TUBEHD mounting pole, while four 4” wheels make transport and positioning quick and effortless.
Connectivity and protection are built in, with XLR input and output for clean signal routing, locking powerCON TRUE1 connectors for secure power input and pass-through, and onboard limiting to safeguard performance under demanding conditions. The PSA18S is a robust, tour-ready subwoofer solution that delivers impactful low end with reliability and ease of use.
