JBL has introduced two pro-style loudspeaker monitors designed to bring studio grade performance to home audio. The JBL 4367 and 4429 combine the company’s iconic pro-audio design with a number of acoustic refinements. Distribution is through Karma-AV.

The JBL4367, with distinctive blue front baffle and exposed mid/high-frequency horn, can be used in two-channel Hi-Fi stereo systems and JBL Synthesis applications in a 2.2 configuration with S2S-EX subwoofers, or in an L/C/R configuration as part of a complete JBL Synthesis theatre.

It borrows drivers and technologies derived from the company’s M2 Master Reference Monitor. These include the brand’s patented D2 compression driver technology featuring the D2430K dual-diaphragm/dual-voice-coil driver, which employs two ring-shaped diaphragms and dual voice coils, for greater output and power handling, to deliver an extended high frequency response to 40kHz.

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.

The speaker also uses a cast aluminium frame woofer modified from the M2, with a new spider and surround treatment. Dual 75mm voice coils made from a pure pulp cone material deliver a low-frequency performance down to 30Hz.

The 4367 also features front-panel high frequency and ultra-high frequency trim adjustments, to fine tune audio response to the system and room. Maximum output power is 300 watts.

The 4367 is available in a choice of furniture-grade walnut or black walnut finishes, and retail for £11,800 a pair.

The sibling JBL 4429 system is an updated version of the company’s 4425 studio monitor, introduced back in 1985. That model was the first JBL design to combine a compression-driver and Bi-Radial horn with a large-format woofer. The new JBL 4429 incorporates a 19mm titanium diaphragm, ultra-high frequency compression driver, and improved 50mm titanium diaphragm high frequency compression driver, in a one-piece SonoGlass horn system.

Built for high (200W) power handling, the 4429 is available in walnut veneer and retails for £5,800.
