Like all JBL Professional products, PRX400 Series speakers undergo our legendary 100-hour stress test to ensure they’ll perform perfectly over a lifetime of long, loud nights. Every speaker is subjected to a barrage of environmental and strength tests: By exposing our products to harsh temperatures and humidity, we make certain they’ll function flawlessly anywhere your gigs take you. And, we conduct pull tests on suspension points, drop tests on cabinets, and crush tests on packaging to ensure that you can hit the stage with confidence and pride.


PRX400 Series speakers are engineered to support diverse, demanding audio environments. The 12-inch, 2-way PRX412M and 15-inch, 2-way PRX415M can be configured as mains or monitors, and with the addition of the PRX418 18-inch subwoofer provide a sub/sat system that generates up to 135 dB of full-range, professional-quality sound. The 15-inch, 2-way PRX425 loudspeaker is the perfect choice for DJs and bands who need low-frequency extension with the convenience of a standalone cabinet.


As part of the HARMAN family of professional audio companies, JBL develops technologies in collaboration with sister company Crown Audio. By accessing sophisticated sound-shaping DSP technology used in Crown XTi2 amplifiers, we offer enhanced JBL performance tunings as presets in Crown products. Not only have we coded crossover points for sat/sub setups, we’ve taken advantage of Crown’s parametric filters and peak x+ limiters to craft an optimal tuning curve that highlights the true potential of the system design.


Every detail of PRX400 Series speakers has been thoughtfully designed for maximum versatility and ease of use. Ergonomically engineered handles make carrying, mounting and positioning each enclosure easy; they’re made from lightweight, glass-filled nylon for added strength and durability and are intelligently engineered for comfort and balance. Optional Gator bags and gas-assist and manual-adjust speaker stands provide a reliable foundation for your next gig, event or club tour.
