JBL JRX100 Series JRX118SP 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.

The JRX118SP is an 18 inch directradiating powered subwoofer. A built-in 500 watt (peak) amplifier accepts stereo or mono line level inputs via balanced, XLR connectors as well as single channel speaker level input via a 1?4inch phone jack. Integral signal processing includes a stereo crossover and limiting for the internal amplifier. A pair of XLR output connectors may be used to pass the input signals to another system or to send a high-passed, line-level stereo signal to a pair of powered, full-range speakers. The JRX118SP is designed to supplement and extend the low frequency performance of full-range systems in live sound and music playback applications. It is an excellent choice for use with powered full-range speakers or in systems using powered mixers. Key Features: •The rugged enclosure is constructed from 19 mm (3?4in) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for durability and improved lowfrequency performance. The enclosure is covered in black carpet. •Heavy duty, all steel handles are used. •A top mounted, cast aluminum 35 mm pole mount receptacle can receive an optional SS3BK pole to facilitate use of the JRX118SP as a base for a mid-high speaker cabinet. •Built-in 500 watt (peak), 300 watt (continuous) amplifier. Controls, connectors, and indicators are clearly labeled with large, highcontrast graphics for easy operation in poorly lit environments. •Integral, preset limiter prevents clipping distortion. An LED illuminates to indicate that limiting is taking place. •Line-level stereo inputs are summed before being sent to the subwoofer’s internal amplifier. This feature allows the JRX118SP to operate in stereo systems using a single subwoofer. •An integral crossover also provides balanced, line-level, stereo, highpassed outputs to feed powered satellite speakers or an external amplifier for passive satellites. •A speaker-level, 1?4" TS phone jack is provided. This input is useful in applications, such as those employing powered mixers, in which it is more practical to bring a full-range, speaker-level signal to the subwoofer amplifier. |
