JBL JRX118SP 18" Powered Subwoofer, 55Hz-300Hz Frequency Response, 230V (Europe Only)
Your card will only be charged once item ships.
The JBL JRX118SP is an 18-inch, direct-radiating, 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 ¼"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.
