JBL 4309 Bookshelf Monitor Speakers Announced

JBL announces a distilled, more compact version of its 4349 bookshelf monitor speakers.

JBL's 4309 Studio Monitor features a 2410H-2 1-inch compression driver mated to the latest High-Definition Imaging (HDI) horn which is joined by a 6.5-inch, cast frame pure-pulp cone woofer.

An Ultra High-frequency tonal adjuster is located on the front panel below the horn and allows the sound to be tailored to your taste and room. The control works with the JBL 4309's crossover network design that features air-core inductors, cast wire-wound resistors and low-ESR metallised film capacitors, all said to optimise the speaker's performance according to the maker. The result is a claimed 42Hz – 30kHz (-6dB) frequency response from these 4 ohm-rated loudspeakers.

The 419mm x 260mm x 227mm (HxWxD) cabinet is braced with 3/4-inch thick walls incorporating a bass-reflex design with dual front-firing flared ports. Around the rear, you'll find twin sets of gold-plated binding posts suitable for single-ended or bi-wire/bi-amplified connections. Meanwhile, you'll undoubtedly notice the front baffles sports JBL's iconic blue in honour of the brand's 75th anniversary this year.

 Jim Garrett, Senior Director, Product Strategy and Planning, HARMAN Luxury Audio, told StereoNET:

The combination of the JBL 4309's powerful woofer, compression driver, and horn harmoniously combine to render music with authority and accuracy, a performance impossible with traditional loudspeaker design.

Finally, the JBL 4309 has been awarded the “Red Dot” as part of the Red Dot Design Award [2021] program.

The JBL 4309 Studio Monitor will be available for purchase from June for £1,799 in a choice of walnut (with a blue cloth grille) or black walnut (with a black grille) satinwood veneers.


While the retro styling of the JBL 4309 might not to be everyone's taste there is no denying the heritage of these studio monitors. With that in mind, if the JBL 4349 are too big for your room, the 4309 should accommodate you nicely and still deliver the sound profile you are hoping for.
