JBL JRX212 12 in. Two-Way Stage Monitor Loudspeaker System B-Stock
The JRX212 is a compact, versatile two-way monitor ideal for home studios, small live rooms, and portable session setups. Dual non-resonant steel handles and a 19 mm MDF enclosure make it straightforward to position and integrate into your monitoring chain, while the robust construction ensures reliable operation across extended recording and mixing sessions without fatigue or coloration.
Acoustic Performance & Coverage
This system delivers 99 dB sensitivity and a 129 dB maximum SPL, providing commanding monitoring output even at moderate amplifier levels—useful for capturing accurate reference in untreated rooms. The dual-angle pole-mount socket with 10° tilt capability allows flexible placement for optimal listening position and acoustics, while the Advanced Network Topology Crossover Design at the low-mid transition ensures smooth integration between the dedicated low and high frequency drivers, maintaining clarity and balance across the critical midrange where mix decisions are made.
Drivers & Power Handling
The JBL M112-8 woofer features a 64 mm edgewound ribbon voice coil—providing greater wire cross-sectional area than round designs for improved efficiency and extended headroom. Paired with the JBL 2414H-C compression driver fitted with a 25 mm polymer diaphragm, the system handles 250 watts continuous and 1000 watts peak without distortion, supported by an 8 Ω nominal impedance and recommended amplifier range of 250–500 watts @ 8 Ω.

What amplifier power do I need to run the JRX212?
