The JBL SRX718S is an 18-inch high-power passive subwoofer built around JBL's patented 2268H Differential Drive woofer. Its compact, front-firing bass-reflex design works equally well as a satellite subwoofer under full-range tops or as a building block in larger subwoofer arrays, making it a mainstay for rental companies, churches, and mobile DJs. The vented, front-loaded enclosure is heavily braced 13-ply birch plywood finished in JBL's rugged DuraFlex coating, with a CNC-machined 16-gauge steel grille lined with acoustically transparent foam. It handles 800 watts continuous (1600W program, 3200W peak) at 8 ohms, reaching a maximum peak SPL of 130 dB, with usable response from 31 Hz to 220 Hz. A large port area reduces port compression and turbulence for cleaner bass at high output. A threaded 20 mm pole socket accepts a satellite speaker above, and T-nuts allow the optional WK-4 caster kit. Order today from Eclipse Sounds with fast nationwide delivery across Kenya.
