Throughout the decade of the 1970s and beyond, the JBL? Model 4310 was found in more professional recording
studios than any other monitor, setting the standard of power and realism for all that followed. The JBL 4319 studio
monitor, with its unmistakable blue baffle and grille, continues the proud tradition. Engineered to play loud and long
with unequalled dynamics, sonic clarity and tonal accuracy, the 4319 features a massive, 300mm (12-inch) woofer
driven by a Differential Drive? (U.S. patent no. 5,748,760 and other patents pending) dual voice-coil assembly, a
large inverted-dome midrange driver and a fast magnesium/aluminium dome tweeter. Together, these advanced
transducers deliver quick, tight bass, a natural, well-focused midrange and clear, distinct highs to create listening
experiences with all the richness and detail of the original performance. Die-cast transducer frames dissipate heat
to minimize distortion caused by power compression, and a heavily braced enclosure virtually eliminates unwanted
internal resonances. Music professionals and critical listeners have only the highest expectations for JBL studio
monitors, and the JBL 4319 delivers brilliantly.
