JBL PRX412M 12 Inch 2-Way Stage Monitor Speaker 600W PA System

Compact 12-Inch Stage Monitor and Utility Loudspeaker

The JBL PRX412M is a passive 12" two-way loudspeaker designed for stage monitoring, speech reinforcement, live performance, and portable PA applications. Its asymmetrical low-profile cabinet can be used horizontally as a floor monitor or vertically as a main or satellite speaker.

The PRX412M combines a 12" JBL MB112-8 woofer with a 1" JBL 2414H-C polymer-diaphragm compression driver and provides controlled 90° × 50° coverage.

Who Should Choose the PRX412M?

Choose the PRX412M when you need a versatile passive loudspeaker that can serve as a stage monitor, portable main speaker, speech-reinforcement cabinet, or satellite speaker above a subwoofer.

Its compact profile and flexible mounting options make it useful for musicians, venues, houses of worship, schools, event spaces, and portable PA systems.

12-Inch JBL Woofer

The PRX412M uses a JBL MB112-8 12" low-frequency driver designed to provide strong vocal and music reproduction from a compact enclosure.

The speaker is passive and requires a compatible external power amplifier.

1-Inch Compression Driver

A JBL 2414H-C 1" polymer-diaphragm compression driver handles high-frequency reproduction through a 90° × 50° horn.

The coverage pattern is designed to provide smooth on-axis and off-axis response whether the cabinet is used vertically or horizontally.

300W Continuous / 600W Program Power

JBL specifies 300W continuous, 600W program, and 1200W peak power handling.

These are speaker power-handling ratings, not built-in amplifier output. The PRX412M is a passive loudspeaker.

8-Ohm Impedance

The PRX412M has an 8-ohm nominal impedance and should be paired with an amplifier that can safely support the connected speaker load.

Confirm amplifier output, speaker quantity, and wiring configuration before connecting multiple cabinets to the same channel.

50Hz–20kHz Frequency Range

JBL specifies a 50Hz–20kHz frequency range at -10dB and a 62Hz–19kHz frequency response at ±3dB.

This makes the PRX412M suitable for vocals, speech, acoustic instruments, and general full-range reinforcement. For deeper low-frequency impact, pair it with a compatible subwoofer.

Stage Monitor or Main Speaker

The asymmetrical enclosure allows the PRX412M to sit horizontally as a floor monitor while maintaining a low profile that helps preserve audience sight lines.

It can also be used vertically as a main or satellite speaker.

Dual-Angle Pole Socket

The built-in 35 mm pole socket supports both 0° vertical mounting and a -10° down-tilt position for improved audience coverage when used on a tripod or over a subwoofer.

M10 Suspension Points

The enclosure includes twelve M10 suspension points for compatible installation and rigging applications.

Use properly rated hardware and appropriate installation practices for any suspended application.

Speakon and 1/4-Inch Connections

Parallel Neutrik Speakon NL-2 / 1/4" phone combination connectors provide flexible professional speaker connections.

Use appropriately sized speaker wire based on amplifier power and cable length.

Durable Plywood Enclosure

The enclosure is constructed from 18 mm birch/poplar plywood and finished with JBL's DuraFlex coating.

A heavy-duty 16-gauge perforated steel grille with acoustically transparent backing helps protect the drivers during transport and live use.
