JBL 4367 & 4429 retro reprise


Created to bring professional-grade JBL performance to home audio, the JBL 4367 and 4429 studio monitors rekindle a classic lineage by combining new acoustic systems with the company’s iconic pro-audio design, featuring blue front baffles and exposed mid/high-frequency horns.

JBL 4367
The JBL 4367 (above) uses D2 compression driver technology featuring the D2430K dual-diaphragm/dual-voice-coil driver, which employs two annular (ring-shaped) diaphragms and two voice coils to deliver extended high frequency response to 40kHz “with extremely low distortion even at high volume levels. The annular diaphragms are not subject to the break-up modes of a conventional dome surface, and the use of two voice coils yields a dramatic increase in output and power handling.” The D2 driver operates into JBL’s newly developed High-Definition Imaging waveguide, which provides a “neutral frequency response both on and off-axis in vertical and horizontal planes, together with a seamless frequency blend with the woofer”. JBL's 2216Nd 380mm Differential Drive cast aluminium frame woofer from the M2 is modified with a new spider and surround treatment. It employs a pure pulp cone material, dual 75mm voice coils and dual neodymium motor structures to deliver articulate, authoritative low-frequency performance down to 30Hz.
Invoking its control monitor design heritage, the JBL 4367 features front-panel high frequency and ultra-high frequency trim adjustments for the fine-tuning of audio response according to the system and room. Its heavy-duty dual binding posts allow bi-amping or bi-wiring while its 94dB sensitivity and 6 Ohm impedance enable the 4367 to be driven by low powered amplifiers such as valve designs. The bass-reflex enclosure includes dual front-firing ports and is internally braced at critical points to ensure maximum clarity and definition. Available in a choice of furniture-grade walnut or black walnut finishes, the JBL 4367 weighs in at a respectable 61.2 kilos and is classed as a floorstander.

JBL 4429

JBL 4429
The considerably smaller JBL 4429 system is a wholly updated version of the company’s 4425 studio monitor, introduced in 1985. The 4425 was the first JBL design to combine a compression-driver and Bi-Radial horn with a large-format woofer for true studio performance in a transportable size. The new JBL 4429 incorporates a number of important improvements over the 4425 and its successors. Its acoustic design benefits from the addition of a 19mm titanium diaphragm, ultra-high frequency compression driver (138Nd), which joins an improved 50mm titanium diaphragm high frequency compression driver (175Nd-3) in a one-piece SonoGlass horn system.
A new crossover network provides a smooth handover with a 300mm JBL pure-pulp cone woofer (1200FE-8) augmented by twin reflex ports in an improved, braced cabinet for “quick, tight bass, which complements a natural, well-focused midrange and clear, distinct highs”. Combining high sensitivity (91dB (2.83V/1m)), and high (200W) power handling it is available in walnut veneer, the 4429 system includes front mounted MF and HF attenuators and dual gold-plated five-way binding posts.
