Item# PRX425


Affordable, professional performance

PRX425 dual fifteen-inch, two-way is the perfect choice for DJ’s and bands who need low-frequency extension from the convenience of a stand-alone cabinet. PRX400 passive speakers were designed to provide the sensitivity, frequency response and power handling needed to address a multitude of demanding audio environments while still being reasonably priced. For musicians, DJ’s, House of Worship, public address, or suspended in a commercial environment like a school or nightclub, they can be used with a powered mixer or a full rack of amps and signal processing, delivering the sound power and bandwidth necessary to make loud music sound natural and even quiet speech intelligible. Comprised of tour tested JBL components in rugged enclosures with professional connectors and suspension points, three 2-way designs and an 18" sub-woofer tackle tough jobs affordably and professionally.
