JBL JRX212 12-Inch Passive Stage MonitorThe JRX212 is a portable, twelve inch, two way speaker system designed specifically for live performance stage monitoring applications. With enough sensitivity and power handling to cut through the performance volume on stage, the JRX212 has a smooth response so it can deliver maximum gain before feedback. It also includes JBL's dual angle pole socket making it equally at home as a front of house speaker.
