JRX215
JRX215：15' 两路扬声器系统 JRX215 和JRX212 固定安装扬声器
JRX215 和JRX212 是便携式JRX200 扬声器系列中的两个型号产品。两者都是为悬吊安装设计的，不适合作叠积和柱杆安装，因为手柄、脚和柱杆安装插座都已拆除。3 个内部的金属螺栓，吊绳穿到附加的M10眼圈螺栓中。在完整的包装中，提供3 个锻造眼圈螺栓。其他全部特性与相对应的便携式扬声器相同。

FEATURES
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.
JBL 2414H-C 25 mm (1 in ) polymer diaphragm compression driver 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? high frequency 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 high frequency 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° for more uniform audience coverage.
