JBL JRX115 揚聲器
15" 兩路揚聲器系統
這是一種 15" 梯形揚聲器系統，用于多功能廳、歌舞廳和會議擴聲。音箱內配置了美國JBL公司的低頻和高頻驅動單元，配有 35mm 柱桿安裝的雙角度插座、Neutrik 揚聲器使用插座和 1/4" 輸入連接器。
JRX115i 是一種固定安裝的揚聲器系統。3 個 M10 眼圈螺栓和線纜托架替代了便攜式 JRX115 的腳、柱桿插座和手柄。

Two-Way Sound Reinforcement Loudspeaker System
This trapezoidal, 15" speaker system is at home in live sound, dance music and speech reinforcement.
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.
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° for more uniform audience coverage.
