The JBL JRX212 12" two-way passive loudspeaker is ideal for stage monitoring applications and is lightweight and durable thanks to its MDF (Medium Density Fiberboard) construction, making it perfect for touring. The JRX212 is equipped a 12" low frequency driver with a 2.5" diameter edgewound ribbon voice coil for excellent low frequency output along with a 1" polymer diaphragm compression driver for improved high frequency performance. These work together to provide powerful sound output that is clear and punchy sound across the speaker's 60 Hz - 20 kHz frequency range.


  • 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
  • Progressive Transition™ high frequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response
  • Enclosure constructed from 0.75" (19 mm) MDF (medium density fiberboard)
  • SonicGuard™ protects the high frequency driver from excess power without interrupting the performance
  • Non-resonant, all-steel handles
  • 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
