By RS Staff Published: October 20, 2015 ⋅ Updated: April 15, 2019 Harman’s JBL has introduced the 4367 Studio Monitor, created to bring professional-grade JBL performance to home audio. The JBL 4367 incorporates drivers and technologies directly drawn from the company’s M2 Master Reference Monitor to deliver musical realism and sonic accuracy, and features an exposed mid/high-frequency horn driver and a blue front baffle that reflect the 4367’s pro audio lineage. “The JBL M2 has quickly established itself as the new reference standard in professional monitoring environments, and the JBL 4367 brings this high level of sonic accuracy to consumers,” said Jim Garrett, director of marketing and product management at Harman. “With the introduction of the 4367, home listeners everywhere can enjoy listening to music exactly as the artists, producers, and engineers intended it to be heard, from a loudspeaker that truly excels in every sonic respect.” The JBL 4367 features the company’s patented D2 compression driver technology, the D2430k dual-diaphragm, dual-voice-coil compression driver, employs two annular (ring-shaped) diaphragms and two voice coils to deliver extended high-frequency response to 40 kHz with low distortion even at high volume levels. The annular diaphragms are not subject to the break-up modes of a conventional dome diaphragm, and the use of two voice coils yields increased output and power handling. The D2 driver operates into JBL’s newly developed High-Definition Imaging (HDI) waveguide that provides neutral frequency response both on-axis and off-axis in both the vertical and horizontal planes and a sonic blend with the woofer. The unique geometry of the HDI waveguide enables the JBL 4367 to deliver superlative imaging on a realistic soundstage, with a natural tonal balance at nearly any listening position in a wide range of acoustic environments. The 4367 employs the JBL 2216Nd 15-inch Differential Drive woofer used in the M2, modified with a new spider and a new surround treatment. The cast aluminum frame woofer employs a pure pulp cone material, dual three-inch voice coils and dual neodymium motor structures to provide low-frequency performance below 30 Hz. The JBL 4367 features front-panel high-frequency and ultra high-frequency trim controls that facilitate optimal sonic adjustment in any system and room. Its heavy-duty dual binding posts allow bi-amping or bi-wiring. The speaker’s 94 dB sensitivity and 6-ohm impedance enable it to be driven to generous volume levels and it can accommodate up to 300 watts maximum amplifier power. The 4367’s bass-reflex enclosure is tuned via dual front-firing ports and is internally braced at critical points to ensure maximum clarity and definition.
