JBL JRX212 2-way Passive Stage Monitor

The JBL JRX212 is a portable, twelve-inch, two-way speaker system designed specifically
for live performance stage
monitoring applications.


  • 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.
