JBL JRX118SP

 The JRX118SP powered subwoofer incorporates a specially designed amplifier with 500 watts peak and 300 watts continuous power output into the same driver as the non-powered version. It offers dual inputs with balanced XLR connectors, a built-in stereo crossover network and peak limiter to protect the amplifier and speaker from clipping.

All JRX100 series models are constructed of carpet-covered, ¾" MDF - a material that is structurally and acoustically superior to the particleboard that is used by many competitive products. To ensure durability, JBL constructs these enclosures with advanced adhesives and closely mechanically spaced fasteners, while competitive systems typically rely on glue. Non-resonant, all metal handles are used and an 18 gauge, full metal grille protects the drivers. All JRX100 models have passed the same 100-hour, full rated-power torture test that JBL high-end touring systems must survive.
