Affordable, reliable, high quality sound

The JRX212 is a portable, twelve-inch, two-way speaker system designed specifically for live performance stage monitoring applications. The JRX200 series delivers the performance and prestige JBL is known for at an affordable price point. To meet these conflicting design goals, we looked at every element of the speaker system design. We 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, we are going to be building a lot of JRX200 speakers. This means we can apply efficient, high-volume production methods and purchase materials at the lowest cost. That's how JRX200 delivers unprecedented value.

Greater efficiency and power handling

JBL 12 in low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil 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

Advanced network topology crossover design

Shapes frequency response and delivers "coherent summation" in the crossover region

High-voltage capacitors and inductors

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

Rugged, acoustically superior enclosure

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™ protection

SonicGuard™ protects the high frequency driver from excess power without interrupting the performance.

Durable design

Non-resonant, all-steel handles are used along with an attractive 18-gauge hexagon perforated steel grille to protect components from damage.

Dual-angle pole-mount socket

Allows the speaker to tilt 10° for more uniform audience coverage.
