JBL JRX125 Speaker Dual 15 Full Range 500 Watts RMS

JBL JRX125 Details

JRX100 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 JRX100 speakers. This means we can apply efficient, high-volume production methods and purchase materials at the lowest cost. That's how JRX100 delivers unprecedented value.

Progressive Transition™ Waveguide
Just one example of JBL's innovation is the PT™ Waveguide design. For decades, horn designers were faced with trade-offs between well controlled coverage, low distortion, and good frequency response. JBL developed proprietary algorithms which give our PT Waveguides the best performance in all three areas.

Hardware
JRX100 doesn't scrimp on the hardware either. All the JRX models use tough, non-resonant all-steel handles with big, beefy bars. And the entire baffle (not just the woofer) is protected by an 18 gauge steel grille.

JBL Drivers
All woofers and compression drivers used in JRX100 are manufactured in Northridge, California by JBL Professional.
Enclosure Construction
Competitive systems typicall y use particle board construction and rely entirely on glue to hold it together. For JRX100, we selected a more rugged and acousticall y superior 3/4" MDF material for the enclosures. And to make sure they stay together, we constructed them with advanced adhesives and closely spaced mechanical fasteners. Not only are the cabinets rugged, but the denser enclosure walls are more riged, delivering better low end as a result

SonicGuard™
Feedback, dropped microphones, pushing the amps into clipping - all these things can quickly destroy even the best high-frequency drivers. That's why JBL JRX100 speakers include SonicGuard™ protection. SonicGuard circuitry absorbs excess energy without interrupting the performance. No circuit breakers to reset, no fuses to replace and no "poly-switches" to degrade sound quality.

We've all heard shows where the sound was plenty loud and the music was kicking but there just wasn't any energy. Could be that the problem was inadequate bass. If your goal is to get the crowd out on the dance floor, there's no better way to do it than with plenty of tight, punchy, powerful bass. And there's no better way to get bass than with a JBL subwoofer.

The JRX100 line gives you two ways to get the JBL subs you need. If you prefer the simplicity and convenience of a powered subwoofer, choose the JRX118SP. Or if you'd rather have the flexibility of an externally powered rig, go with the JRX118S. Either way you're going to get the performance of a cast-frame, 18" woofer built by JBL.

Elevating your speakers on a tripod stand or pole is a great idea. But, if you raise the speaker too high, half the output hits the back wall causing unwanted acoustic effects. Leave the speaker too low, and the crowd down front gets blasted while those in the rear can't hear. The solution - a pole-mount with two sockets so you have the option of mounting your JRX115 or JRX112M with a 10º down angle. The result - more uniform coverage of your audience and less energy wasted hitting the walls. Of course you can still use the other socket to position your speakers with no down angle.

For those who prefer the simplicity of a self-powered subwoofer, there's the JRX118SP. JBL started with the same woofer used in the non-powered JRX118S and added a specially designed amplifier with 500 watts (peak) and 300 watts (continuous) power output.

Dual 15" speaker systems have become one of the most popular configurations with DJs and musicians who are looking for more low-frequency performance while maintaining the simplicity of a single-box system. The JRX125 is actually a "quasi three-way" design. This means that the upper woofer covers lows and mids. The bottom woofer uses a lower crossover frequency and covers only lows, acting as a built-in subwoofer. So you get the extra low-end of a dual 15" rig while maintaining the superior mid-frequency performance of a single driver system.
