JBL SRX812 12" Two-Way Bass Reflex Passive System

The JBL SRX812 commands a powerhouse presence on any stage, delivering responsive, articulate bass from its 12-inch woofer paired with crystalline midrange clarity from the two-way configuration. You'll feel the musical connection between your performance and what's hitting the audience—every nuance translates with gut-punching low-end authority and uncolored reproduction that keeps your tone honest and present. This passive system rewards you with immediate, engaging feedback that works equally well anchoring hip-hop beats, grooving through funk, or pushing hard rock rhythms with precision and punch.

Audio Performance & Coverage

The SRX812 generates a maximum SPL output of 135dB with sensitivity of 95dB at 1W/1m, ensuring articulate projection across medium to large venues. Its 41Hz–20kHz frequency range at –10dB (with –3dB response from 57Hz–20kHz) and 90 x 50 degree coverage pattern provide seamless integration into distributed systems while maintaining tight, controlled directivity.

Design & Build Quality

Constructed from 18mm plywood with a rugged 14-gauge steel grille finished in durable Duraflex coating, the SRX812 handles the demands of touring and frequent transport. The dual 36mm pole sockets and 12 M10 suspension points provide flexible rigging options, while the 50-degree monitor angle allows tilted deployment for optimal coverage in any configuration.
