Product Description
JRX118SP is a 18 in. Powered Subwoofer and the rugged enclosure is constructed from 19 mm (.75 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.
Product Features
- Durable black carpet to protect from life on the road
- Heavy duty, all steel handles
- 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, high contrast 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, high-passed 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
