Aiming point

JBL's JRX200 loudspeaker line delivers the level of performance and quality you expect from JBL without cleaning out your savings account. The JRX 212 is a portable 12", 2-way speaker designed for stage monitoring in live performance situations.


The JRX212 monitor features a 12" low-frequency speaker and a 1" compression driver with a polymer diaphragm for high performance and system reliability. The high-frequency driver uses a Progressive Transition high-frequency waveguide to provide clearer sound with less interference. The crossover network uses heavy-duty components to allow high power levels and deliver a clear, coherent sound. JBL's SonicGuard technology protects the high-frequency driver from damage caused by excessive sound levels.

Delivery system

The JRX212's rugged 3/4" MDF enclosure features an 18-gauge steel grille and non-resonant steel handles. A dual-angle pole mounting socket and 500-watt maximum power rating allow the JRX212 to double as a PA speaker for smaller systems. Whether for sound reinforcement or stage monitoring, the JBL JRX212 offers the performance and durability JBL is known for in a surprisingly affordable package.

Product Research


Two-Way Stage Monitor: The JBL JRX212 is a portable, two-way speaker designed specifically for live performance stage monitoring applications. The JRX212 employs a 12" low frequency driver with a 2.5" diameter edge-wound ribbon voice coil for greater efficiency and power handling, and a 1" polymer compression driver for improved high frequency performance as well as system reliability.

Progressive Transition Waveguide: The 1" tweeter is coupled with a Progressive Transition high frequency waveguide which provides superior coverage control (90° H x 50° V), reduced distortion, and smoother frequency response.

SonicGuard HF Protection: Integrated SonicGuard protection circuitry shields the high frequency compression driver from excess power without interrupting the speaker's performance.

Rugged Enclosure: The rugged, acoustically superior enclosure is constructed from 0.75" MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance. An attractive 18AWG hexagon perforated, steel grille protects speaker components from damage. The enclosure also features non-resonant, all-steel handles.

Input/Output Connectors: The JRX212 stage monitor speaker is fitted with a Speakon NL4 connector and a 1/4" TS phone plug connectors. There is also a parallel identical Speakon NL4 and 1/4" connector that facilitates a loop-through connection so you can daisy-chain and power an additional JRX212 speaker.

Dual-Angle Pole Sock: The JRX212 stage monitor also includes a dual-angle pole socket (1-3/8") allowing it to be used as a front-of-house speaker.
