JBL MRX-512M 12-Inch 400-Watt Speaker

The MRX512M is a premium, utility/monitor speaker. The MRX512M uses a JBL 262H 305 mm (12 in) Differential Drive woofer and a 2408H 375 mm (15 in) annular polymer diaphragm, neodymium compression driver for 400 watts (continuous) power capacity. A 70° x 70° horn provides smooth, even coverage whether used in the vertical (mains) or horizontal (monitor) orientation.

NL4 connectors are provided on both ends of the speaker to keep cable runs tidy on stage when used in the monitor application and for easy access when used on tripods. A passive network provides accurate reproduction throughout the cross-over region.

For use on a tripod or over a subwoofer, JBL's dual angle pole mount is included. This feature allows the speaker to be mounted in a vertical position or with a 10° down tilt for optimum audience coverage.

The enclosure is constructed of quality plywood and coated in JBL's rugged DuraFlex finish. The attractive CNC-machined, 16-gauge steel grille wraps around the sides of the enclosure. The grilles are internally lined with an acoustically transparent screen to provide additional driver protection and give a very professional appearance.

Applications:
  • Speech reinforcement

  • High-performance satellite speaker for use with subwoofers
Features:
  • 12" Differential Drive woofer for high-power capacity and very lightweight

We used these speakers as mains and bought them because we thought they would be more effective than the 400 series JBLS we were using. We had a hard time driving these enough to get a good volume. We used tow different powered Carvin boards and a 2500 watt Crown power amp. They came highly rated so I am not sure where the problem was coming from--was it user error or the speakers? However, we went back to using the 400 series JBLS and they work pretty well.

          These are one of the most useful stage monitors that I own.
          This speaker is suprisingly light and wonderfully clean sound. Add a pair of 418s subs and they will do fine for FOH at small to medium sized venues as well.

          A step down from the srx712 in maximum output, but a much better value and it gets loud enough for small stages and sounds good doing so with a few EQ cuts.

                  • A:

                    You'll need an amplifier. It won't connect directly to your mixer. Try the EON series for that.

                    A:

                    What you can do is have one speaker on one side and have two connected on the other. That way you can use one as a monitor.
