The JBL 214552 JRX225 Passive PA Speaker is a portable, dual fifteen-inch, two-way speaker system designed specifically for applications in live music performance and music playback.
JBL JRX 225 features: Dual JBL low frequency drivers with a 64 mm (2.5 in) diameter edge wound 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 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? 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 Fibreboard) using advanced adhesives and mechanical fastener technology for extreme durability and improved low-frequency performance. Sonic Guard? 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.
