JRX215
JRX215：15" 兩路揚聲器系統 JRX215 和JRX212 固定安裝揚聲器
JRX215 和JRX212 是便攜式JRX200 揚聲器系列中的兩個型號產品。兩者都是為懸吊安裝設計的，不適合作疊積和柱桿安裝，因為手柄、腳和柱桿安裝插座都已拆除。3 個內部的金屬螺栓，吊繩穿到附加的M10眼圈螺栓中。在完整的包裝中，提供3 個鍛造眼圈螺栓。其他全部特性與相對應的便攜式揚聲器相同。

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.
