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 PTTM 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.

SonicGuardTM 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.

Enclosure Construction Competitive systems typically use particleboard construction and rely entirely on glue to hold it together. For JRX100, we selected a more rugged and acoustically 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 rigid, delivering better low end as a result.

Crossover Network Design-
While the drivers are the muscle of a speaker system, the crossover network is the heart and soul. Just one look at a JRX100 network and a competitive network tells the story. JRX100 networks are built using heavy coils with massive cores and heavy gauge wire so they won't saturate when you drive them hard.

Dual Angle Pole Socket-
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 10° 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.

Put on a set of industrial hearing protectors, step through three sound proof doors and you're in the JBL Power Test room. All JBL Professional speaker designs, including JRX100, come here for a brutal 100 hour torture test. When we specify a speaker as having 250 watts continuous power capacity, that means samples have survived a 100 hour test with IEC noise at 250 watts. And that's 250 watts average – the signal we use actually has 6 dB (1000 watt) peaks. If the systems don't pass, we change the design and start the tests again.

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.

Powered or non-powered– the choice is yours.
JRX115i and JRX112Mi Installation Versions The JRX115i and JRX112Mi are installation versions of portable JRX100 models. Both are designed for suspension where ground stacking or pole mounting is impractical or undesirable. Handles, feet and pole-mount socket have been removed. Three internal metal braces, threaded to receive M10 bolts have been added. To complete the package, three forged M10 eyebolts are provided. All other performance characteristics are identical to their portable counterparts.
