JBL JRX212 12″ 2-Way Stage Monitor Portable Loudspeaker System
The JBL JRX212 2-way passive stage monitor gives you professional performance affordably. JBL engineers reexamined every element of the speaker system design, kept everything that makes a speaker perform and sound its best, and redesigned things that don’t. For increased efficiency and power handling, the JRX212 sports a 12″ low-frequency driver with a 2.5″-diameter edgewound ribbon voice coil that delivers more cross-sectional wire area in its voice coil gap than round-wire designs, while a 1″ polymer-diaphragm compression driver maximizes high-frequency performance and system reliability.

Key Features
- JBL 12 in low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling.
- JBL 2414H-C 25 mm (1 in) polymer diaphragm compression driver improves high frequency performance as well as system reliability.
- The advanced network topology crossover design shapes frequency response and delivers “coherent summation” in the crossover region.
- High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high-power without saturating.
- Progressive Transition high frequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response.
- The rugged, acoustically superior enclosure is constructed from 19 mm (.75 in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance.
- SonicGuard protects the high frequency driver from excess power without interrupting the performance.
- Non-resonant, all-steel handles are used.
- Attractive 18-gauge hexagon perforated, steel grille protects components from damage.
- Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage.
