JRX21 is a portable, fifteen-inch, two-way speaker system designed specifically for applications in live music, playback, and reinforcement of speech. With the smooth, natural soundingmid-range of the system, the JRX215 does a great job projecting live vocals, solos and speech.
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 hexagon perforated, steel grille protects components from damage.
|
- Dual-angle pole-mount socket allows the speakers to tilt 10° for more uniform audience coverage.
