JBL SRX812 12" Two-Way Bass Reflex Passive System

The JBL SRX812 is a 12 inch two way passive sound system designed for musicians, DJs, rental houses, and installers who need strong output and clear detail in a single cabinet. With peak power handling of 3200 watts, it supplies the headroom required for club dates, outdoor events, and fixed installations without breaking a sweat.

At its core sits JBL’s patented Differential Drive woofer. By using dual voice coils and a lighter magnet structure, this design keeps weight under control while extending low-frequency response down to 41 Hz. A precision waveguide and compression driver handle the highs, so vocals and instruments remain articulate even when the system is pushed hard.

Deployment is simple in almost any venue. M10 suspension points allow installers to fly the cabinet safely, and a standard pole socket makes ground stacking easy for rental rigs. Turn the speaker on its side and it forms a thoughtful stage monitor, giving performers focused coverage without extra brackets.

The cabinet relies on plywood, a textured coating that meets tour grade standards, and a perforated steel grille to survive frequent transport. Ergonomic handles and a manageable 55 pound weight let one person load in or out with minimal strain.

Factory tunings for Crown ITech HD and XTi 2 amplifiers as well as the dbx VENU360 processor streamline system setup and help deliver consistent results. Whether you need a main PA for a mobile DJ rig, additional fills in a church, or a rugged box that can handle nightly rentals, the SRX812 offers the performance and flexibility to get the job done reliably.
