The JBL JRX 212 is a Passive PA Speaker, offering 250 Watts @ 8 Ohms, with a 12" Woofer, and a 1" Compression Driver. The JRX 212 is a portable, twelve-inch, two-way speaker system designed specifically for live performance stage monitoring applications. JRX 200 delivers the performance and prestige JBL is known for at an affordable price point. To meet these conflicting design goals, they looked at every element of the speaker system design. JBL kept everything that makes a speaker perform and sound its best and we eliminated things that don't. With performance, value and popular price points, JBL are going to be building a lot of JRX 200 speakers. This means they can apply efficient, high-volume production methods and purchase materials at the lowest cost. That's how JRX 200 delivers unprecedented value.
The main features of the JBL JRX 212 include:
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 damage
Dual-angle pole-mount socket allows the speaker to tilt 10°for more uniform audience coverage
