PRX400 passive speakers were designed to provide the sensitivity, frequency response and power
handling needed for almost any professional audio environment while still being reasonably
priced. Whether you use a powered mixer or an equipment rack full of amps and signal
processing, PRX400 passive speakers deliver the sound power and bandwidth necessary
to make loud music sound natural and even quiet speech intelligible.
PRX400 passive speakers are comprised of tour tested JBL components and feature professional
®
connectivity via Neutrik
constructed from an 18mm Birch/Poplar multi-laminate hardwood covered in highly resilient
™
DuraFlex
M10 suspension points for safe deployment in light duty installations. With three
2-way designs and an 18" sub-woofer, PRX400 passive series tackle tough jobs
and feature rugged 16 gauge steel grilles. All full range models utilize twelve
Speakon combination connectors. PRX400 cabinets are artfully
affordably and professionally.

At Home Anywhere
Perfect for musicians, DJ’s, House of Worship, public address, or even suspended in a commercial environment like
a school or nightclub, PRX400 speakers were crafted to address a multitude of demanding audio environments.
The PRX412M and PRX415M can be used as mains or monitors and with the addition of the PRX418 subwoofer
you’ll have a sub/sat system capable of generating 135 dB of full-range, high quality audio. The PRX425 dual 15"
two-way is the perfect choice for DJ’s and bands who need low-frequency extension from the convenience of a
stand-alone cabinet.
Survival of the Fittest
Like all JBL Professional products, the PRX400 Series
speakers have survived JBL’s 100 hour power test. We
submit each component and each system in the PRX400
Series to 100 hours of continuous, high level input.
Very few of our competitors survive the brutality, but
this test ensures that your JBL speaker will perform
perfectly for a lifetime of long, loud nights. We
also submit all of our speakers to a barrage of
other unforgiving environmental and strength
tests. By exposing our products to harsh
temperatures and humidity we can make
certain they will function anywhere on
the planet. We conduct pull tests on
the suspension points, drop tests
on the cabinets, and packaging
crush tests in an effort to ensure
that you can hit the stage with
confidence and pride.
Enhanced Performance
As JBL Professional is part of the Harman family of professional audio companies, we
have a unique opportunity to partner with sister company Crown Audio. By accessing the
sophisticated sound shaping DSP technology employed in their Crown
are able to offer enhanced performance tunings as a pre-set in their products. Not only have
we coded the crossover points for a sat/sub setup, we’ve utilized their parametric filters and
peak x+ limiters to craft a beautiful tuning curve that highlights the true potential of the system
design. Tunings will also be available in the dbx DriveRack® PA+ signal processor.
