JBL JRX212 2-Way Passive, Unpowered Loudspeaker

Its smooth frequency response, reduced distortion, and rugged enclosure makes the JBL JRX212 an affordable, professional choice for stage monitors. Unpowered. Requires separate power amplifier.

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


- JBL 12" low frequency driver with a 64 mm (2.5 in) diameter edge wound 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 read more coverage.

Note: Unpowered speaker, requires separate power amplifier.
