We have tested the JBL 4349 studio monitor!

JBL is headquartered in Northridge, California. The JBL 4349 studio monitors are compact in size. The JBL 4349 studio monitors are capable of clear, definite and deep bass. The 32 Hz bass response is quite low, so there is no need to use a subwoofer.

Features of JBL 4349


This is a two-way, bass-reflex studio monitor speaker that can be placed on a stand or shelf. Recommended receiver power: 25 – 200 WRMS. Frequency transmission: 32 Hz to 25 Hz, crossover frequency: 1.5 kHz, sensitivity: 91 dB. Rated impedance: 8 Ohm.

The high and ultra high frequency parts can also be adjusted independently using the switches on the front panel.


The 300 mm subwoofer provides high output with low distortion. The 75 mm sound coil guarantees maximum output with minimal distortion.


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

Dimensions: 736.6 mm x 444.5 mm x 317.5 mm, weight: 37.7 kg. A separate stand is available for purchase.


This compact speaker is available in walnut or black. They are quite heavy, so they are not so easy to move. The housing is made of stiffened 25 mm thick MDF boards. It has a front double reflex port. Due to the size of the speaker, it also fits comfortably with a 30 cm subwoofer, 2 reflex holes and a horn tweeter.

There is a pair of ring membranes made of 38 mm Teonex polymer inside the device. The cross-section of the membrane is V-shaped, which the manufacturer says reduces distortion.

This characteristic horn radiator is made of Sonoglass, a fiberglass-based composite, and is designed to significantly increase the distortion caused by a standard horn.

The style of the speaker is retro, the company’s classic blue baffle and grille make it instantly recognizable.


Testing took place in a medium-sized studio. We tested the pair of monitors with a NAD T758 V3 receiver. Some absorption panels with diffusers were placed on the walls of the studio, and deep-absorbing corner elements with membranes in the corners provided the right sound. Based on our measurements, the ceiling will even need some broadband acoustic panels for perfect sound.

When choosing speakers, an important consideration is where and for what purpose you want to use them. It doesn’t matter what type of speaker you choose for your studio or your home theater system. The JBL 4349 is a good choice in both cases.

The JBL 4349 studio monitor was surprisingly sharp and produced dynamic depths. We heard extended, clear highs. We found much better sound compared to the previously tested studio monitors. It was characterized by a wide stage picture, accurate and detailed production. His open, neutral sound was amazing. If we still had to find a flaw, we would mention the slight blur in the lowest ranges, and the lack of fine detail and a stable, clear sound in some places while listening to classical music.

The bass sounded so dynamic, fast, and powerful that we didn’t feel the urge to get a separate subwoofer at all. However, bass sounds are not the biggest strengths of this speaker. The middle and high tones were clear and extensive, with flawless dynamics.

For optimal sound, place the speakers at a suitable distance from the wall, each other, and the listening position. It is a good idea to place the monitors on a stand, because if you place them on a piece of furniture, cabinet, or bookshelf, you may be facing a resonance problem.


These compact speakers offer unique and unparalleled clarity, intense bass and dynamics. It is perfect not only for studio monitoring, but also for a home sound system or musical parties. You can expect realistic, spacious sound if you choose the JBL 4349.
The bass are amazingly percussive, you can’t complain about the middle and deep sounds either, they were dynamic and clear. The speaker box has a solid, resonance-free design.
The price could be a little more affordable.
