It has a double gold-plated connector. The woofer is a 300 mm pressed paper diaphragm with a cast basket, the tweeter is the JBL patented D2415K dual 38 mm high frequency compression driver.

Dimensions: 736.6 mm x 444.5 mm x 317.5 mm, weight: 37.7 kg. Optional stand available.

Design

This compact speaker is available in walnut or black. They are quite heavy, so they are not so easy to move around. The cabinet is made of 25 mm thick MDF boards. It has a front dual reflex port. Due to the size of the speaker, the 30 cm woofer, the 2 reflex ports and the horn tweeter fit comfortably.

A pair of 38 mm Teonex polymer ring diaphragms are located inside the unit. The diaphragm has a V-shaped cross-section, which the manufacturer claims reduces distortion.

This distinctive horn radiator is made of Sonoglass – a glass fibre-based composite – and is designed to significantly increase the distortion caused by a conventional horn.

The style of the speaker is retro, with the company’s classic blue baffle and grille making it instantly recognisable.

Testing

Testing took place in a medium-sized studio. The monitor pair was tested with a NAD T758 V3 amplifier. The walls of the studio were fitted with a few acoustic panels with diffusers, and in the corners, membrane deep absorption corner elements ensured the right sound quality. Based on our measurements, the ceiling will also need some broadband acoustic panels for perfect sound.

An important consideration when choosing speakers is where and for what purpose you want to use them. It makes a difference which speaker you choose for your studio or home theatre system. The JBL 4349 is a good choice for both.

The JBL 4349 studio monitor produced surprisingly powerful and dynamic bass. We heard extended, clear highs. Compared to the studio monitors we had previously tested, we experienced much better sound. It had a wide stage image, accurate and detailed production. Its open, neutral sound was amazing. If there were any faults to be found, it would be the slight blurring in the lowest ranges and the lack of fine detail and stable, clear sound when listening to classical music.

The bass was so dynamic, fast and powerful that we felt no urge to buy a separate subwoofer. Nevertheless, the bass is not the biggest strength of this speaker. The mids and highs were clear and extended with impeccable dynamics.

For optimum sound, it is advisable to place the speakers at an appropriate distance from the wall, from each other and from the listening position. It’s a good idea to place the monitors on a stand, because if you put them on furniture, a cabinet or a bookshelf, you’re likely to encounter resonance problems.

Conclusion

These compact speakers offer unique and unrivalled clarity, intense bass and dynamics. Not only perfect for studio monitoring, but also for home sound systems or music parties. You can expect a realistic, spacious sound when you choose the JBL 4349.
The lows were incredibly punchy, and the mids and lows were dynamic and clear. The speaker’s cabinet is of a solid, resonance-free design.
The price could be a little more affordable..
