| JBL 15 in. low frequency driver with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more cross-sectional wire area in the voice coil gap than round wire designs, for greater efficiency and power handling. Ferro-fluid cooled compression driver with titanium diaphragm improves high frequency performance as well as system reliability. The advanced network topology crossover design shapes the frequency response to deliver coherent summation in the crossover region. High-voltage capacitors and inductors with massive cores and heavy gauge wire enable the crossover network to handle high power without saturating. Progressive Transition highfrequency waveguide provides superior coverage control, reduced distortion, and smoother frequency response. The rugged, acoustically superior enclosure is constructed from 19 mm (.75 in ) MDF (Medium Density Fiberboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance. SonicGuard protects the highfrequency driver from excess power without interrupting the performance. Non-resonant, all-steel handles are used. Attractive 18-gauge perforated, steel grille protects components from damage. Dual-angle pole-mount socket allows the speakers to tilt 10 degrees for more uniform audience coverage.
A sophisticated, advanced network topology design is utilized in JRX100 models to ensure quality performance. To minimize distortion due to coil saturation, heavy gauge wire is used for inductors and SonicGuard high-frequency driver protection guards against damage caused by inadvertent overpowering of the system. All full-range models feature Neutrik Speakon and 1/4" input connectors.
All JRX100 series models are constructed of carpet-covered, 3/4" 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.
A new feature of the JRX100 line is the dual-angle pole socket. This feature allows the speaker to be mounted in either a conventional, vertical position, or with a 10 degree down angle. By aiming the speaker down, it is possible to achieve more even audience coverage and reduce the destructive acoustic reflections from walls.
The dual-angle pole socket is featured on two JRX100 models - the JRX115 and the JRX112M. The JRX115 is a 15" two-way front-of-house speaker with 1000 watts peak power capacity and 250 watts continuous.
