JBL Professional MRX515 Speaker System

JBL Professional is constantly pushing the threshold for better, more useful products for the working musician and DJ and once again JBL Professional hits the target with their MRX500 Series loudspeakers. The MRX500 delivers outstanding performance for the DJ and musician where a smaller, lighter, more portable system is required with no sacrifice in sound quality or durability. Up to 30% lighter than comparable systems, the MRX was designed from the ground up utilizing JBL's Differential Drive® transducer technology. Specifically engineered for MRX and completing the design, a series of rugged plywood enclosures, covered with JBL’s DuraFlex™ finish, a tough, textured scratch resistant surface, that ensures years of solid performance and professional good looks.

The MRX515 is a portable, high performance, fifteen-inch, two-way speaker system designed for reinforcement of music and speech in entertainment, live or pre-recorded applications. It makes an ideal high-performance satellite speaker for use with subwoofers.

The MRX515 is high-power, lightweight two-way loudspeaker system offering a very high level of performance from a speaker that can be placed on a pole or standard speaker tripod stand. A passive crossover network provides accurate reproduction throughout the cross-over region. JBL's dual angle pole mount 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 DuraFlexT 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.

Detailed Features

Dual Pole Angle Socket Drawing

Dual Pole Angle Socket

Elevating your speakers on a tripod stand or pole is a great idea. But, if you raise the speaker too high, half the output hits the back wall causing unwanted acoustic effects. Leave the speaker too low, and the crowd down front gets blasted while those in the rear can't hear.

The solution, a pole-mount with two sockets so you have the option of mounting your MRX515 with a 10ş down angle. The result, more uniform coverage of your audience and less energy wasted hitting the walls. Of course you can still use the other socket to position your speakers with no down angle.

JBL 2408H Compression Driver


The MRX515 utilises a 380 mm (15 in) JBL 265H Differential Drive® woofer which handles 400 watts continuous, yet the entire system weighs only 19.5 kg (43 lbs). For the high frequencies, a JBL 2408H 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver is mounted to a 70° x 70° horn.

100 Hour Torture Test

Like all JBL Professional products, the MRX Series is brutalized in JBL’s speaker torture test. Unique in the industry, the JBL torture test submits each component in the MRX Series to 100 hours of continuous, high level input, ensuring that the MRX will deliver its extraordinary sound even after years of tough handling and thousands of hours of performance.
