JBL JRX118SP, 18" Powered Subwoofer. 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.
The JRX118SP features...
- Dual inputs with balanced XLR connectors.
- A built-in stereo crossover network - great for systems with EON or other powered satellite speakers.
- >Peak limiter that protects the amplifier and speaker from clipping.
Specifications- Frequency Range (-10 dB): 38Hz - 300 Hz
- Frequency Response (±3 dB): 55Hz - 300 Hz
- Amplifier Power : Peak: 500 watts: Continuous: 300 watts with <0.2% THD
- Maximum SPL: 123dB
- Dimensions (H x W x D): 597 mm x 516 mm x 597 mm (23.5 in x 20.3 in x 23.5 in)
- Weight: 40.4 kg (89 lbs)
- Low Frequency Driver: JBL2043-G
- Input Connectors: XLR/M(x2) (line level, balanced): ¼" TS phone jack (x1)(speaker level)
- Output Connectors: XLR/F (x2) Selectable, Thru or High Pass
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 typically use particle board 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 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.
