The JBL SRX818S is a high-output 18-inch passive subwoofer engineered for demanding professional sound reinforcement. It pairs a robust 2279 18-inch 8 ohm low-frequency driver with a heavyweight enclosure to deliver solid low-end extension and impressive punch. With 600 W continuous, 1200 W program and 2400 W peak power handling, the SRX818S delivers authoritative bass that keeps its composure at high levels, reaching a peak SPL of up to 129 dB. Frequency response is tuned for musical, controlled output from 45 Hz to 150 Hz, with usable range down to 28 Hz for extra depth when required.
System integration is straightforward thanks to factory tunings for Crown amplifiers and dbx processors, along with full support in Harman Audio Architect for fast, repeatable deployment. Whether you are building a compact ground-stacked rig or reinforcing a larger FOH system, the SRX818S slots in seamlessly and scales with your inventory.
Ideal for live music, DJ events, touring, and installed sound in clubs, theatres and houses of worship where tight, powerful low-frequency reinforcement is required.
