The JBL JRX212 12" Two-Way Stage Monitor is a portable loudspeaker designed with a low frequency driver and a 2.5 inch diameter ribbon voice coil. This monitor delivers even more cross sectional wire area in the voice coil than the basic round wire designs. This allows the highest level of efficiency and power handling. The JBL JRX212 12" Two-Way Stage Monitor was designed with high voltage capacitors and inductors. This loudspeaker has been engineered with massive cores and heavy gauge wire allowing the crossover network to handle super high power while eliminating saturation. The Progressive Transition high frequency waveguide brings industry topping line coverage control along with reduced distortion and a much smoother frequency response. The rugged and acoustically remarkable enclosure on this high end loudspeaker is built from a .75 inch Medium Density Fiberboard. JBL engineers used super advanced adhesives and a mechanical fastener technology for the ultimate durability and hugely improved low frequency performance. The JBL JRX212 12" Two-Way Stage Monitor is a truly excellent choice for large stages and venues.
