JBL JRX212

The 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 TransitionT 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.
SonicGuardT 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.
