Description
JBL PRX418S 18" Subwoofer
The PRX418S is a compact, road-ready subwoofer that delivers authoritative low-end extension without excessive bulk. Its front-loaded vented design and robust construction make it equally at home in fixed installations or touring rigs, handling demanding SPL requirements across a wide range of venues.
Design & Build
Built with a birch/poplar multi-laminate hardwood enclosure finished in durable DuraFlex, the PRX418S resists wear from transport and harsh environments. The 16-gauge steel grille with CNC-machined construction and acoustically transparent lining protects the 18" JBL Selenium woofer while maintaining clean sonic output.
Audio Performance
The PRX418S integrates seamlessly into sub/sat systems, providing tight, focused low-frequency reinforcement from 35–250 Hz (-10 dB) with a usable peak response of 52–120 Hz (+3 dB). Its 800W continuous / 1600W program / 3200W peak power handling and 130 dB SPL peak maximum output deliver clean, controlled bass even at extended throws.
