12 in. Two-Way Stage Monitor Loudspeaker System
The JRX212 is a portable, twelve-inch, two-way speaker system
designed specifically for live performance stage monitoring
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
Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform
