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.
  • Frequency : 35Hz – 40kHz (–6dB)
  • Weight: 16.3kg (35.9 lb)
  • Nominal impedance: 6 ohms
  • Sensitivity: 92dB (2.83V/1m)
  • Amplifier power: 200 watts RMS
Brand: JBL
Model: 4319

 The JBL 4319 studio monitor, with its unmistakable blue baffle and grille, continues the proud tradition.

Engineered to play loud and long with unequaled 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/aluminum 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 resonance.

Music professionals and critical listeners have only the highest expectations for JBL studio monitors, and the JBL 4319 delivers brilliantly.
