JBL 4349 Studio Monitor Review

Around two years prior JBL presented the L100 Classic (checked on here), an advanced variant of the 1970 L100 speaker complete with Quadrex froth grille. Seeing the refreshed rendition of the speaker from the notable Memorex promotion was cool, and evidently I'm in good company to have that impression. The L100 was a hit, and JBL delivered more in its series of new speakers dependent on famous plans yet using new innovation. The JBL 4349 ($7,500) is an enormous stand-mounted screen with an uncovered horn that takes up the top third of the bureau. It very well may be had in either a Black Walnut Wood facade with a dark barbecue or a Satin Walnut Wood Veneer with a blue grille. Go with the Satin Walnut Wood Veneer to expand the retro styling sway.

It might resemble an oldie but a goodie, however JBL's retro-propelled 4349 studio screen comes loaded with the organization's new pressure driver and HDI waveguide.Whichever finish works for you, it's the enormous, dark, shaped composite horn that is probably going to get your consideration when you first see it. The horn is JBL's new High-Definition Imaging ("HDI") waveguide, which houses another 1.5-inch double stomach pressure driver. The lower part of the horn has a board with high-recurrence and super high-recurrence trim controls. The grille covering the lower part of the speaker conceals a 12-inch woofer and a couple of front-terminating ports. The bureau estimates 29 inches high, 17.5 inches wide, and 13.5 inches down, and tips the scales at a strong 83 pounds. The quality of the facade is well done, and the fundamental MDF bureau is strong and very much supported. The details given by JBL express the ostensible impedance as 8 Ohms, with 91 dB effectiveness. Recurrence reaction is evaluated at 32Hz to 25kHz (±6dB).

Before I continue on to talking about arrangement and tuning in, I needed to examine the D2415k pressure driver. It depends on the D2430k utilized in the profoundly respected M2 speaker framework however involves double drivers a large portion of the size as in the M2. The ring-formed polymer drivers utilize a "V" molded math said to diminish separation modes. This new driver is matched with the HDI horn, which goes about as a huge waveguide to give an advanced scattering design. The Sonoglass composite material utilized for the HDI horn is thick and sonically inactive.

The vast majority of my listening was finished with the 4349's being controlled by the Naim Uniti Atom. The 4349s should be put on a stand, so I matched them with the JS-120, a stand that works with a few JBL speakers. The 4349s sit on the stands with practically no mechanical association.

It might resemble an oldie but a goodie, however JBL's retro-propelled 4349 studio screen comes loaded with the organization's new pressure driver and HDI waveguide.Joss Stone's "The Chokin Kind" from her collection The Soul Sessions (Tidal, Virgin) sounded somewhat more slender in the midrange than they did through the as of late investigated B&W 603 S2s or any of the Performa Be models from JBL's sister organization, Revel. The general impression is that of a recessed midrange and more forward high pitch. I attempted various settings of the trim controls and observed turning up the HF change leveled the equilibrium a piece. However, the 4349 plainly outperformed different speakers as far as productivity and lucidity in the upper midrange or more. Regardless of whether mated with the humble Naim or a bigger Krell intensifier, the 4349s played very uproariously and neatly. There were no indications of stress or separation.

Paula Coles' "Tiger" from This Fire (Tidal, Warner) gave an exercise to the 4349's 12-inch woofer. I realize that some might be distrustful of a straightforward paper woofer, however the 4349 is verification that JBL stays equipped for planning entirely competent drivers with more normal materials. For this situation, the generally high hybrid point implies the woofer needs to cover a wide recurrence range. I viewed the bass notes as full and strong however inadequate with regards to a portion of the itemized subtlety I found in the as of late explored Revel F228Be and F328Be and Magico A3 speakers.

JBL 4349 Pros And Cons


The JBL 4349 expands upon the notable retro plan of JBL studio screens, which have been a pillar in proficient settings for a really long time.

The blend of a 12-inch driver and an enormous, ported nook gives solid, full-bodied bass.

The 4349 is very effective and can play uproariously with only a couple of watts of intensification. Fortunately the 4349 is equipped for keeping up with very low contortion levels at incredibly high volumes, keeping up with its levelheadedness well beyond the point numerous speakers would be self-destructing sonically and maybe even truly.


There is an observable plunge in the midrange. I had the option to dial in better apparent equilibrium utilizing the tone controls, yet never enough to totally dispose of the hesitant midrange.

The JS-120 stand appears to be somewhat weak for the 4349. I can perceive how it would be ideal for a more modest speaker, however the 4349 is a major kid. This may not be a worry for low-traffic regions, yet assuming you are putting the speakers in moderate-to high-traffic regions, they ought to be on stable stands that precisely associate with the speaker.

How does the JBL 4349 contrast with the opposition?

There are not many stand-mounted speakers of this size that I can imagine, so the probable contenders to the 4349 are other horn-based, retro-styled plans. Two strike a chord immediately: JBL's own 4367 ($15,000) resembles a leveled up 4349 however includes a 15-inch woofer and a similar pressure driver used in the profoundly respected M2. My restricted listening experience with this speaker was extremely certain.

Klipsch, another veteran horn-speaker maker, likewise offers the Heritage Cornwall IV ($5,998),a three-way with a 15-inch woofer.


The JBL 4349 is an incredible blend of present day innovation and old-school feel. The blend of the all-new D2415k pressure driver and new HDI waveguide gives staggeringly unique highs, with quick homeless people and great imaging, while at the same time remaining very spotless and liberated from twisting. While many "8 Ohm" speakers have critical impedance plunges that make them harder to drive, the 4349 stayed simple to drive neatly and noisily. While I didn't have any low-fueled cylinder enhancers to give a shot with the 4349s, I firmly speculate they would turn out great. The speakers never appeared to pressure even humbly controlled enhancers, including a Russound MBX-Amp, which had the option to drive the 4349 levels sufficiently to make discussion unimaginable without hollering, notwithstanding putting out a small 50 watts for every channel.

While I was not actually an enthusiast of the midrange plunge, a portion of my companions who got an opportunity to tune in with me loved 4349's voicing. The wide scattering given by the HDI horn gave a wide perfect balance to different audience members. We as a whole concurred that the mix of apparently easy elements, detail, and absence of mutilation of the upper midrange and high pitch were amazing. Assuming you love the exemplary studio screen style yet need to exploit the new advancements in speaker innovation, the JBL 4349s merit taking a nearby pay attention to
