Product description


JBL Professional PRX400 Series 18″ High-Power Subwoofer is designed to provide the sensitivity, frequency response and power handling needed for almost any professional audio environment while still being reasonably priced. Whether you use a powered mixer or an equipment rack full of amps and signal processing, PRX400 passive speakers deliver the sound power and bandwidth necessary to make loud music sound natural and even quiet speech intelligible. PRX400 passive speakers are comprised of tour tested JBL components and feature professional connectivity via Neutrik Speakon combination connectors. PRX400 cabinets are artfully constructed from an 18mm Birch/Poplar multi-laminate hardwood covered in highly resilient DuraFlex and feature rugged 16 gauge steel grilles. All full range models utilize twelve M10 suspension points for safe deployment in light duty installations.

With three 2-way designs and an 18″ sub-woofer, PRX400 passive series tackle tough jobs affordably and professionally. Perfect for musicians, DJ’s, House of Worship, public address, or even suspended in a commercial environment like a school or nightclub, PRX400 speakers were crafted to address a multitude of demanding audio environments. Rugged 16-gauge grilles provide serious protection for the JBL tour tested components. Backed with acoustically transparent cloth the grilles are designed for sonic accuracy, structural strength and professional good looks.

Permanently mounting the PRX400 is easily managed via twelve built-in M10 suspension points constructed from 14 gauge steel. They have been tested with a yield-strength of 1000 pounds each ensuring a safe and secure mount. Ergonomically engineered handles are made from light-weight glass-filled nylon for added strength and durability. Intelligently engineered for both balance and comfort in the hand, they make carrying, mounting and positioning each enclosure easily managed in any situation.
