Jamo Studio 7 Series: a successful comeback for the Danish giant?


Mis à jour le 25 October 2022.

Jamo Studio 7
The speakers in the Jamo Studio 7 range are suitable for music and home theater. The pack we tested included a pair of Jamo S27F floorstanding speakers, a pair of Jamo S17B speakers and the Jamo S43C center speaker.

The Jamo Studio 7 range marks the return of the Danish manufacturer to the passive speaker market. These new releases have a typically Scandinavian minimalist design. They feature specific drivers and rigorously selected components to provide an energetic and detailed sound without distortion. The manufacturer has also worked on the phasing of the drivers by tilting the cabinet back by 7°, hence the name of the series. We were able to test the Jamo S17B bookshelf speakers (€549), the Jamo S27F floorstanding speakers (€949) and the Jamo S43C center speaker (€329). 

Can Jamo reach previous heights of success with this promising speaker range?

Jamo includes a set of metal spikes and rubber feet with the Jamo S27F floorstanders. The bookshelf and center speakers only come with rubber feet.

The Jamo S27F speakers come with a set of adjustable spikes and a set of rubber feet. The latter are also included with the Jamo S17B and Jamo S43C speakers.

The included spikes decouple the Jamo S27F floorstanding speakers from the floor. Their height can be adjusted if the speaker is placed on an uneven surface.

Jamo Studio 7 Series: presentation

The new Jamo Studio 7 range includes six models. There are two pairs of bookshelf speakers (Jamo S15B and Jamo S17B) and two pairs of floorstanding speakers (Jamo S25F and Jamo S27F). These speakers are suitable for both music and home theater. They are accompanied by two center speakers (Jamo S25C and Jamo S43C), which are ideal for home theater use. 

The manufacturer therefore offers two home theater speaker systems: the Jamo S17HCS pack (€1,299) and the Jamo S25HCS pack (€1,499). Naturally, it is also possible to create your own custom 5.0 or 7.0 channel system with the different speakers in the range. 

The range comes in two different colors: cobalt blue (the version we tested) and light gray.

Bulky yet appealing

The Jamo Studio 7 speakers are quite massive, as their width and depth are quite significant in relation to their height. The 6.7” midbass drivers of the Jamo S17B and Jamo S27F reinforce this bulky appearance. The embossed pattern on the cones also accentuates the feeling of power emanating from these speakers.

Apart from the Jamo S43C center speaker, the speakers in the Jamo Studio 7 range are quite massive, but they are still charming.

Despite this, the speakers are still very appealing. The rounded vertical edges soften their silhouettes. The silver color of the base, the baffle and the rings around the drivers provides an elegant contrast with the cabinet. The light gray and cobalt blue finishes are finely textured and seem robust. The construction is rigorous, the details are meticulous.

7° tilt

The Jamo Studio 7 speakers get their name from their cabinet, which is tilted back to a 7° angle. This optimizes the phasing of the bookshelf and floorstanding speakers’ drivers. As a result, the time alignment of the various frequencies is improved to provide a more coherent soundstage.

The Jamo Studio 7 bookshelf and floorstanding speakers’ titled cabinet optimizes the phasing of the drivers.

Moreover, the speakers’ angled base houses the various elements of the crossover. Carefully selected to provide a precise and clear sound, the inductors and electrolytic capacitors are placed far away from the driver magnets. Isolated from any interference, they can reproduce the tiniest details in recordings.

The base of the floorstanding and bookshelf speakers in the Jamo Studio 7 range houses the crossover. Composed of passive components, it is physically isolated from the driver magnets to eliminate any interference.

Embossed paper cone midbass driver

All of the speakers in the Jamo Studio 7 range have a two-way bass-reflex design. They feature one or several midbass drivers with an embossed paper cone. Each cone has an embossed “T” pattern that improves rigidity. It effectively reduces the risk of cone deformation, resulting in less distortion, even at high volume. The transient response is also improved. All of these factors ensure tight, energetic bass.

Tweeter and waveguide

The Jamo Studio 7 speakers are equipped with a 1” soft fabric dome tweeter. This tweeter unit uses a copper faraday ring to increase sensitivity and decrease distortion. It is also mounted at the center of a small waveguide to ensure uniform high frequency distribution. Thanks to the latter, directivity is reduced and the sound remains balanced, even outside of the speaker’s axis. Lastly, the rounded edges of the cabinet reduce sound wave diffraction. This design limits the baffle effect and the resulting coloration of the sound.

Placed in a waveguide, the tweeter provides low directivity to improve the coherence and balance of the soundstage, even outside of the speaker’s axis.

Jamo Studio 7 Series: listening conditions

For our review of the Jamo Studio 7 Series speakers, the manufacturer sent us a Jamo S43C center speaker, a pair of Jamo S17B bookshelf speakers and a pair of Jamo S27F floorstanding speakers. 

We used them with a Denon A/V receiver to enjoy Qobuz in high resolution via the Roon playback software. The TCL 65C825 mini LED TV and Pioneer UDP-LX500 4K UHD Blu-ray player also allowed us to watch a few movies and series.

For this test, we paired the Jamo Studio 7 speakers with a Denon AV receiver that was connected to a TCL 4K TV and a 4K Blu-ray player. We were able to listen to music and watch movies and series to test the audio qualities of these speakers.

Jamo Studio 7 Series: our impressions

During stereo music sessions, the Jamo Studio 7 speakers displayed impact and energy. The level of details wasn’t the highest and the outlines weren’t the clearest, but the soundstage was pretty wide and the depth was satisfactory. The speakers were respectful of the original recordings: the vocals and instruments were realistic and quite nuanced. However, precision was sometimes lacking with more rapid and complex tracks. The power handling was good, and there was no saturation or coloration at high volume. We enjoyed a pleasant sound at moderate volume.

Jamo Studio 7 S17B
With the Jamo S17Bs, the bass was energetic and tight, the midrange expressive and the high frequencies smooth.

With the Jamo S17B bookshelf speakers, the lows had a good foundation and were energetic and tight. They weren’t terribly deep, but we didn’t find this particularly frustrating. The mids were expressed with conviction. The vocals were correctly positioned and realistically embodied in front of the listener. The high frequencies were somewhat in the background. We would have liked them to have been a little more incisive and smooth.

Jamo Studio 7 S27F
The Jamo S27F floorstanding speakers are characterized by a nice presence in the lows which, unfortunately, lack depth. The mids are balanced and the highs are very soft.

Naturally, the Jamo S27F floorstanders offered lows with more presence. The latter were ample, responsive and punchy. However, they weren’t much deeper than with the bookshelf speaker. Given its size, we expected more from this model! Compared to the S17B, the mids were more withdrawn and weren’t as expressive. Overall, we found the Jamo S17B bookshelf speaker to be more balanced.

Jamo Studio 7: home theater pack
In home theater use, the Jamo Studio 7 speakers were engaging, with a solid foundation in the bass and an excellent spatialization of effects. The coherence of the soundstage was remarkable.

In a home theater setup, the Jamo Studio 7 speakers were in their element. They offered good energy and excellent responsiveness. On the soundtracks of both The Rings of Power and Saving Private Ryan, they really immersed us in the different atmospheres. The Jamo S43C center channel speaker had no trouble asserting itself next to the Jamo S27F floorstanding speakers. Dialogues were rich and perfectly clear. From both the front and the back, effects were distributed with assurance and coherence throughout the room. The bass was powerful and well controlled. The addition of a subwoofer, however, will provide more immersion.

Jamo Studio 7 Series: compared to…

Elipson Prestige Facet HCM 14F System 5.0

Elipson Prestige Facet HCM 14F System 5.0

The speakers in the Elipson Prestige Facet HCM 14F System 5.0 pack are a little more precise and detailed than the Jamo models. They also offer more nuance across the different frequency ranges. Moreover, they deliver more extensive bass with (just like the Jamos) a lot of energy. Design-wise, we preferred the Jamo Studio 7 speakers.

B&W 603 S2 25th Anniversary Edition HC 5.0

B&W 603 S2 Édition 25e Anniversaire HC 5.0

Sold for over €2000, the speakers of the B&W 603 S2 25th Anniversary Edition HC 5.0 pack inherit technologies from more premium ranges. The double aluminum dome tweeter of the British speakers delivers a transparency that the Jamos can’t match. As for the Continuum cone, it offers more substantial and nuanced mids than the Scandi speakers’ paper cone, even though the latter provides great presence in this frequency range.

Monitor Audio Bronze 200 HCM 5.0.2

Monitor Audio Bronze 200 HCM 5.0.2

The Monitor Audio Bronze 200 HCM 5.0.2 speakers’ C-CAM tweeter provides more clarity and accuracy than the Jamo pack. However, the highs delivered by the Studio 7 speakers are smoother and more velvety. In addition, their 6.7” drivers offer more extensive and energetic lows.

Jamo Studio 7 Series: who are they for?

The speakers in the Jamo Studio 7 range will appeal to those who enjoy an energetic and lively sound. Music lovers and home theater enthusiasts alike will enjoy the expressive mids and punchy, albeit not very deep, bass. They will also be impressed by the beautiful design and elegant finish of these speakers.

Jamo Studio 7 Series: conclusion

The Danish manufacturer has achieved its goal with the elegant and impressive speakers in the Jamo Studio 7 Series. They offer great energy and can withstand listening sessions at high volumes without creating any coloration or saturation, in both music and home theater setups. They are not the most detailed in their price range, but they exhibit a nice overall balance and remarkable coherence. They may lack bass depth, but this can easily be compensated for by adding a subwoofer. Models like the Dali Sub E-9 F or the GoldenEar ForceField 3 are ideal.

Jamo Studio 7
The Jamo Studio 7 speakers will delight movie and series fans, allowing them to create a very convincing home theater speaker system for under €2000 if they choose the models in this review.

We liked

  • The design and finish
  • The energy and impact in the lows
  • The expressive mids

We would have liked

  • More precision
  • For the lows to have been deeper
