The JRX112M 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.
  • Ferro-fluid cooled compression driver with titanium diaphragm 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 highfrequency driver from excess power without interrupting the performance.
  • Non-resonant, all-steel handles are used.
