JBL PRX300 Series – Value Speakers for Live Performance




Available in India through Narain Pro Audio & Lighting LLP – Harman Professional’s official distribution partners – the PRX300 is a new set of value speakers developed by JBL Professional for live performance and installed sound applications. The new series comprises of four models:

  1. PRX312MD (12” two-way stage monitor)
  2. PRX315D (15” two-way speaker)
  3. PRX318SD (18” subwoofer)
  4. PRX325D (Dual 15” two-way speaker)

The PRX312MD, PRX315D, and PRX325D are two-way speaker systems that feature a JBL 2412 1-inch ferro-fluid cooled compression driver with a titanium diaphragm that enables the speakers to deliver clean and warm high notes with uncompromised reliability. JBL SonicGuard technology improves system stability by protecting the high frequency driver with additional protection offered through the precision-crafted crossover network that feeds the two drivers with clear-cut frequencies with minimum overlap. It can capably handle high power with its high-voltage capacitors and inductors. The patented Progressive Transition waveguide mounts on top of the tweeter and provides superior coverage control, reduced distortion, and smoother frequency response. Each speaker uses a premium low frequency driver (12”/15”) with an edge-wound ribbon voice coil of 2 ½ inch (64mm) in diameter that assures solid bass, high efficiency and large power handling capabilities. The PRX325D features two 15” low-frequency drivers, wherein the upper woofer operates at mid and low ranges while the lower woofer focuses on bass only, thereby delivering extended low-frequency performance, and eliminating the need for additional subwoofers.

For applications that demand the need of a dedicated low-frequency fidelity source, the PRX318SD compact direct-radiation 18-inch subwoofer system proves to be the perfect solution; with its JBL 2043-G 18-inch woofer and 3-inch voice coil in a direct radiation format reproducing loud and powerful low frequencies. The sub system is capable of handling 350 watts of continuous power with a peak of 1400 watts.

All four models in the series feature rugged cabinets constructed with MDF (Medium Density Fiberboard) for extreme durability and improved low frequency response. Two all-steel handles integrated to the sides of the case make transport and setup easier, while the front of the units sport a dent-resistant grille made from 18-gauge perforated steel that protects the components from damage. A 36-mm socket allows mounting of the PRX312MD, PRX315MD, and PRX325MD on a speaker pole and work as a main or fill, with the socket supporting either up-straight standing or 10° tilting. A 36-mm pole mount receptacle on the top of the PRX318SD receives the SS3BK pole to facilitate use with either of the above loudspeakers.
