JRX212

Key Features:

䉴

JBL 12 in low frequency driver

with a 64 mm (2.5 in) diameter

edgewound voice coil which

provides more cross-sectional wire

area in the voice coil gap than

round wire designs, for greater

efﬁciency and power handling.

䉴

JBL 2414H-C 25 mm (1 in) polymer

diaphragm compression driver

improves high frequency

performance as well as system

realibility.

䉴

The advanced network topology

crossover design shapes frequency

response and delivers “coherent

summation” in the crossover

region.

䉴

High-voltage capacitors and

inductor s with massive cores and

heavy gauge wire enable the

crossover network to handle high

power without saturating.

䉴

Progressive Transition™ high

frequenc y waveguide provides

superior coverage control, reduced

distortion, and smoother frequency

response.

䉴

The rugged, acoustically superior

enclosure is constructed from

19 mm (.75 in) MDF (Medium

Density Fiberboard) using

advanced adhesives and

mechanica l fastener technology for

extreme durability and improved

low-frequency performanc e.

䉴

SonicGuard™ protects the high-

frequenc y driver from excess

power without interrupting the

performanc e.

䉴

Non-resonant, all-steel handles are

used.

䉴

Attractive 18-gauge hexagon

perforate d, steel grille protects

component s from damage.

䉴

Dual-angle pole-mount socket

allows the speaker to tilt 10° for

more uniform audience coverage.

The JRX212 is a portable, twelve-inch, two-way speaker system designed

speciﬁcally for live performance stage monitoring applications. With enough

sensitivity and power handling to cut through the performance volume on

stage, the JRX212 has a smooth response so it can deliver maximum gain

before feedback. It also includes JBL’s dual-angle pole socket making it

equally at home as a front-of-house speaker.

1. “Frequency Range” and “Frequency Response” are based on half-space response.

2. “Power Capacity” and “Peak Power Capacity” ratings are based on the average and peak power capacity of product

samples subjected to a 100 hour power test using random noise with a 6 dB crest factor, in accordance with IEC

standards.

3. Height dimension includes feet.

JBL continually engages in research related to product improvement. Some materials, production methods and design

reﬁnements are introduced into existing products without notice as a routine expression of that philosophy. For this

reason, any current JBL product may differ in some respect from its published description, but will always equal or

exceed the original design speciﬁcations unless otherwise stated.
