roksponsmallKarma-AV has added two new JBL studio monitors to its high-end JBL Synthesis range. 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.

The JBL 4367 incorporates drivers and technologies derived from the company’s M2 Master Reference Monitor. It utilises JBL’s patented 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 high frequency response to 40kHz with 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 (HDI®) 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 low-frequency performance down to 30Hz.Drawing on 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 to generous volume levels by up to 300 watts maximum amplifier power. The 4367’s bass-reflex enclosure includes dual front-firing ports and is internally braced at critical points. Available in a choice of furniture-grade walnut or black walnut finishes, the JBL 4367 can be used in 2-channel Hi-Fi stereo systems as well as JBL Synthesis applications in a 2.2 configuration with S2S-EX subwoofers, or in an LCR configuration as part of a complete JBL Synthesis theatre.

The JBL 4429 system is an 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 a braced cabinet. Built for high sensitivity (91dB (2.83V/1m)), and high (200W) power handling, the 4429 is designed to reproduce the dynamic richness and detail of the original performances at all listening levels. Available in walnut veneer, the 4429 system includes front mounted MF and HF attenuators and dual gold-plated five-way binding posts.
