18 in. Powered Subwoofer

For those who prefer the simplicity of a self-powered subwoofer, there's the JRX118SP.

 

特点

  • 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.
  • 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 W (peak), 300 W (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, .25 in 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.
