The JBL's PRX315D 2 Way passive speaker employs a quality 15-inch low frequency driver with a 2 12 inch edge-wound ribbon voice coil to deliver robust bass, great efficiency, and big power handling capabilities to the system. A 1-inch ferro-fluid cooled compression driver with titanium diaphragm gives clear and warm high notes as well as uncompromised reliability to the system. Apart from the drivers, the system's fault-free performance is dependent on the crossover network, which feeds the two drivers with clear cut frequencies with minimal overlap and can handle high power thanks to its high-voltage capacitors and inductors. The innovative Progressive TransitionTM waveguide is mounted on top of the tweeter and delivers improved coverage control, decreased distortion, and a smoother frequency response to the system.
For high durability and increased low frequency response, the PRX315D encloses all acoustic components in a durable cabinet made of 15mm MDF (Medium Density Fiberboard) with innovative adhesives and mechanical fastener technologies. To make transit and setup easier, the case has two all-steel handles built into the sides. The PRX315D can be mounted on a speaker pole and used as a main or fill speaker thanks to a 36-mm socket.
