The SRX828S dual 18" subwoofer brings serious low-end power to any venue, from intimate gigs to large-scale productions. Built for concert touring and permanent installations alike, this powerhouse achieves a maximum SPL of 141dB whilst maintaining the versatility needed by musicians, bands, DJs, and sound engineers. Its wide stance design accommodates top box splaying, whilst indexing feet allow for both standard and cardioid stacking configurations. JBL's engineering attention to detail shines throughout the SRX800 Series, with every component purposefully designed for real-world applications. The ergonomically crafted handles provide a comfortable, non-fatiguing grip that makes transport and setup straightforward, whilst M10 suspension points, indexed feet, and pole/tripod mounts offer flexible array configurations for any installation requirement. At the heart of this subwoofer lies JBL's patented Differential Drive Technology ferrite drivers, featuring 3" voice coils paired with lower mass ferrite magnets. This combination reduces overall weight whilst increasing power handling capacity and providing exceptionally low distortion with extended low frequency response. The inclusion of JBL's 2432H neodymium compression driver - the only 3" voice coil driver in its class - ensures high power levels with smooth, crystal clear sound reproduction. Crown ITech HD tunings and presets are available for optimised performance integration.
