The JRX218S is loaded with a massive JBL 18" woofer featuring a stamped steel frame and 3" voice coil. It is rated at 350 watts (continuous) and 1400 watts (peak)—and that's based on JBL Professional's 100 hour torture test. Recommended crossover settings: 30 Hz high pass filter, 24 dB/octave and an 80 to 100 Hz low pass filter, 24 dB/octave. The JBL JRX218S delivers the performance and prestige JBL is known for at an affordable price point. Components: JBL M118-4 18" woofer.

The JRX200 Series doesn't scrimp on the hardware. 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 grill.
All woofers and compression drivers used in the JRX200 Series are manufactured in Northridge, California by JBL Professional.
Competitive systems typically use particle board construction and rely entirely on glue to hold it together. For the JRX200 Series, JBL selected a more rugged and acoustically superior 3/4" MDF material for the enclosures. And to make sure they stay together, they 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.
"Power Handling" and "Peak Power Handling" ratings are based on the average and peak power capacity of product samples subjected to a 100 hour power test using random noise with a 6 dB crest factor, in accordance with IEC standards.
