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 ( in)
* 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 subwoofers 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, 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. 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 inch 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
