JBLJRX212M 12" 2-Way Passive Loudspeaker System With 1,000W Peak Power Handling
1/4
Independent shopping perspective
The Korena take
Built around stage-monitor use, the JRX212M is a 12-inch, two-way passive loudspeaker with a 1-inch compression driver on a Progressive Transition waveguide. Its 8-ohm load and recommended 250–500 W amplifier range make the amplifier requirement clear, while the speaker itself is rated at 250 W/1,000 W. The stated 90° horizontal by 50° vertical dispersion helps define its coverage area. A pole mount also allows placement on a speaker stand or subwoofer.
Strong match
Who this is for
- Live-performance stage monitoring with a 250–500 W amplifier into 8 ohms.
- Monitor placement where 90° horizontal and 50° vertical coverage is required.
- Using a monitor on a speaker stand or atop a subwoofer.
Consider the trade-offs
When to look elsewhere
- Systems that require a powered monitor rather than a passive loudspeaker.
- Amplifiers outside the stated 250–500 W recommendation into 8 ohms.
