JBL PRX500 Series Loudspeakers
 For every musician, DJ, venue and audio/video provider, high-performance self-powered speaker systems offer a degree of simplicity unmatched by traditional amp and speaker PA systems. Not only are all components matched right out of the box, but they are optimized for maximum reliability. By considering every element in each system and its contribution to the final application PRX500 redefines high performance portable PA. Through design, PRX500 delivers the power, performance and simplicity you need in a package that's been designed to move.
JBL TECHNOLOGY
JBL Professional has been designing leading edge transducers and systems for over 60 years. Concentrating a design focus on continual improvements in higher power handling, smoother frequency response characteristics, lower distortion, less power compression the result is higher and higher performance levels. Now with the introduction of Differential Drive(r) technology not only do we continue on that path but we are now reducing the weight of the components by incredible amounts.
POWERED BY CROWN
Crown has been designing amplifiers for more than 40 years, always incorporating the best of proven technologies and state-of-the-art advancements into their products. The result: a history of rock solid reliability and a dedication to quality and innovation. The final application is always the most critical element of every design.
PERFORMANCE BY DESIGN
It's the fusion of world leading JBL Differential Drive(r) transducers matched with the power of a multi-channel Crown class-D amplifier that delivers all the PRX500 power and performance at about 30% less weight than competitive products. So what makes it portable? It's not just the light weight and in the case of PRX500 it's not just by adding a handle. Not only are the components significantly lighter, the entire enclosure was designed for maximum ease of transport. From engineered enclosures to protective end-caps to ergonomic handles. Each element has been critically designed to make more than the sum of parts, to make high performance self-powered portable PA that's actually portable.
Each model in the PRX500 Series is unique. Not only has each model been designed to excel within a specific application, but to perform seamlessly with the other systems, providing the ability to up-scale your PA. If the first PRX500 system you own is a pair of PRX512Ms, then guaranteed they will still play a crucial role in your PA system when it's grown ten times its size.
NEODYMIUM COMPRESSION DRIVERS
High frequencies are handled by the new 1.5" annular polymer diaphragm compression driver. The use of a polymer contributes to lower distortion than other similar sized titanium compression drivers. A neodymium motor reduces the weight and size. And the discrete design of the phase plug and bullet provide seamless acoustical transition to the waveguide resulting in crystal clear highs and sonic accuracy. Patent Pending.
WAVEGUIDES
When the audience area you have to cover varies from room to room an optimized
waveguide with a predictable coverage pattern is called for. Whether using one
system or pairing systems together in stacked arrays, the PRX500 waveguides
ensure excellent coverage and pattern control with exceptionally low distortion.
DIFFERENTIAL DRIVE TRANSDUCERS
PRX500 utilizes the latest range of JBL's patented Differential Drive(r) transducers. This new range of 400 watt drivers continue to deliver the same extended frequency response, high power output and low distortion as all JBL transducers have been designed to do. It's the unique Differential Drive technology that enables all the performance in a dramatically lighter package. The dual- coil /dual -gap design places the neodymium magnet inside the voice coil assembly efficiently eliminating the need for massive steel pole pieces as found in conventional drivers. The light weight aluminum chassis is also the heatsink, designed to efficiently lower voice coil temperatures and reduce performance-robbing power compression.
POWERED BY CROWN
Class -D amplifiers have been used in the grueling world of professional car audio for years. They are light, efficient and extremely durable, even in the harshest environments. Using this topology Crown designed a remarkable power solution for PRX500. With a fully featured DSP front end, not only does the amplifier section weigh in at less than 9 lbs, it is capable of producing up to 400 watts per channel, across all three available channels. And at no expense to audio quality, right down to the lack of cooling fan noise: there are none, all heat is dissipated via its efficient passive cooling system.
FLEXIBILITY & SELECTION
Input connections are simply made via 1/4" phone jacks or XLRs, the PRX518S provides the flexibility of a stereo loop-thru connection for efficient sub/sat configurations and with the simple press of a button a dedicated precision crossover is applied to the system. To fine tune further the system can be optimized by simply reversing the polarity. All full - range models feature two frequency response settings; "FLAT" for maximum accuracy and reproduction and "BOOST" for extra low frequency weight and highs that will brighten pre-recorded material and enhance any program at lower play-back levels. The PRX512M is unique, as each selectable frequency response setting has been optimized for use as either a front of house speaker, or a dedicated floor monitor, without compromise. Not only does each full-range system have a calibrated level control, but also the ability to switch between a 'mic' and a 'line' level input: yes, for single mic application you don't need a mixer!
DESIGNED CONSTRUCTION
Using the latest mechanical design software and material implementation, including the use of JBL's rugged DuraFlex finish, the PRX500 enclosures have been designed to withstand the abuse of the tour van, without compromising on aesthetics and more importantly adding unnecessary weight.
BUILT-IN PROTECTION
Heavy-Duty protective end caps, independent of the acoustic enclosure construction, effectively create a protective double wall top and bottom. A custom perforated steel grille protects the components. Its acoustically transparent foam backing not only gives each system a high level aesthetic design, but further protects the components.
PORTABILITY
A newly designed handle, this is where form meets function. Not only has it been designed and size optimized for all the PRX500 powered systems, it's practical use of materials, i.e. nonresonant robust ABS for the back plate and a solid durable, but light-weight chunk of aluminum for the bar... all wrapped in an ergonomically focused rubber grip, make it one of the most highly designed handles in the JBL speaker system catalogue.
