Professional Powered Two-Way 12-inch PA Loudspeaker
The JBL PRX912, part of the PRX900 Series of powered loudspeakers and subwoofers, takes professional portable PA performance to a new level with advanced acoustics, comprehensive DSP, unrivaled power performance and durability and complete BLE control via the JBL Pro Connect app. The PRX900 Series is a versatile solution for DJs and bands, music venues, rental houses, corporate A/V providers, or anyone who needs durable professional systems that deliver powerful, room-filling sound in any portable or installed scenario.

This powered two-way 12-inch loudspeaker is built entirely from the ground up to leverage JBL’s most advanced acoustic innovations. A next-generation driver system—powered by an ultra-efficient Class D amplifier—delivers clarity and definition at maximum volume, with improved dispersion and smooth low-frequency extension.

PRX912’s class-leading DSP package, accessible via an onboard color LCD or the JBL Pro Connect app, features 12-band parametric EQ for system tuning and nuanced tonal control; integrated dbx DriveRack technology includes live and fixed Automatic Feedback Suppression, soft system limiter with Soundcraft Overeasy option and speaker delay settings and presets.

The JBL Pro Connect app provides complete hardware and DSP control of up to 10 speakers; integrate PRX900 Series models with JBL EON ONE MK2, PRX ONE and EON700 systems and access app-exclusive functions including speaker snapshots and grouping.

The PRX912 is designed to withstand the rigors of the road. Its composite cabinet features a computer-modeled internal ribbing design that increases overall cabinet rigidity, which improves acoustic performance and durability. Like with every JBL product, everything is reinforced by industry-leading test and validation protocols.
