JBL designed the popular JRX100 series for cost-conscious musicians, DJs and other users of live sound reinforcement speakers. All full-range models feature Neutrik Speakon and 1/4 inch input connectors. JRX100 cabinets are constructed of carpet-covered, 3/4 inch MDF - a material that is structurally and acoustically superior to the particleboard that is used by many competitive products.
JBL constructs the JRX enclosures with advanced adhesives and closely mechanically spaced fasteners, not just glue. They use non-resonant, all metal handles, and an 18-gauge, full metal grille. All JRX100 models have passed the same 100-hour, full rated-power torture test that JBL high-end touring systems must survive.
