PASSIVE SPEAKER ( SPEAKER PASIF ) JBL JRX 212
12 in. Two-Way Stage Monitor Loudspeaker System
FEATURES :
JBL 12 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 frequency response and delivers " 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 speaker to tilt 10° for more uniform audience coverage.
