JBL    JRX125    扬声器 双15" 两路扬声器系统

双 15" 扬声器系统是迪斯科舞厅的大众化的一种系统配置，也是音乐家们期待的具有更低频响特性的简单实用的单音箱系统。JRX125    实际上是一种“准三路扬声器系统”的设计。意味着低频扬声器覆盖了低频和中频频段，作为超低音扬声器使用。因此，这种双    15"    配置可在保持单驱动器优良的中频特性外，同时还可获得双    15"    配置的超低频带特性。

Dual 15" Two-Way Sound Reinforcement Loudspeaker System

The JRX125 is a portable, dual fifteen-inch, two-way speaker system designed specifically for applications in live music performance and music playback.

 

FEATURES

Dual JBL low frequency drivers with a 64 mm (2.5 in) diameter edgewound ribbon voice coil which provides more crosssectional 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 frequency response and delivers coherent summation in the crossover region.

A "Quasi 3-Way" design offers the extra bass for which a dual fifteen system is designed, but without sacrificing performance in the critical mid-range. The upper woofer produces mid-frequencies and bass, while the lower woofer concentrates on bass only. The reduction in mid-range phase cancellation greatly improves midrange sound quality and coverage.

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.
