Is this box too good to sound true? Far from! The new Sonus Faber Liuto inspires both heart and mind

  1. Review: “Sonus Faber Liuto” speakers to 4000 euro
  2. Data sheet

Liuto is of course – Italian – and referred to a musical instrument that is popular in the Renaissance and the Baroque: the lute. From the perspective of the engineer, it belongs to the tough tasks due to their delicate tone. And so require a box, which is of course especially because, named after her to shine most tender tones. Dare one would find it you already if the optical impression: gently curved shapes and leather dominate the impression. Since many technicians could cherish the fear, the installed drivers and the sound adjustment be a beautiful speaker secondary virtues, finally he sell himself so well. A thesis, which is of course far from Sonus President Cesare Bevilacqua: You invest as much effort in chassis development and sound like in the finish. And the budget for Sonus relationships is rather scarce in this case: the new, which at the same time represents a top of the range of a whole series is narrow 4000 euros.


That competent developers at work who proves even the concept: the flawless 3-way system separates at 350 and 3000 Hertz. This is the way to ensure that the measured 15 cm midrange driver – a special woven and then baked plastic – covers the entire formant area. These are those pitches, formed the vocal sounds of the human voice so over the timbre of a voice as well how about the sound of the vowels. Some speakers experts might argue now that at least a part of the voice range to the woofers distributed in the sense of uniformity and thus not a seamless transition is possible. This is technically correct, in practice but the hearing in this field locates already very inaccurate. And the advantage resulting from a discharge of the smallish sized main tweeter bass and fundamental interests, weighs more due to the resulting clarity. Especially since the bass beyond any doubt is raised, to be able to play as a Basic sound: his 22 cm diaphragm from an aluminium-magnesium alloy promises power, but at the same time control. The already narrow housing of the Liuto is rounded towards the rear to reduce resonance and standing waves. A conglomerate equal to three minimal differently tuned reflex tubes should provide for a better suggestion of space in the Tiefstton and also keep a minimum compression.


Such threatening of course also in the treble range, where everything is filigree. At the Liuto Sonus developers opted not for the ring radiator has almost become a trademark, but for a classic fabric dome tweeter. That may not quite the upper limit frequency and reach of the detail of the ring, but promises significant benefits in terms of dynamics and clarity, especially when the coupling is slightly lower. Gently adjust the angle to the already bundling in 3000 Hertz midrange, a small hollow slightly limited the angle of the tweeter. The soft front cover in fine leather and the bevelled edges of the box do to rest. Also during the processing there – is already almost typical for Sonus – to forgive only top marks, the Italians have mastered a black piano lacquer obviously just as perfectly as the processing of solid wood in the significantly higher priced series.


“Creamy” – that was the spontaneous adjective, that the colleagues Bernhard Rietschel blurted out after the first listening test with the Liuto. Now, you can be divided about whether can be sufficiently described a box so the sound, but the warm, pleasant and yet sweet character of the Sonus seems to attack even sober and die-hard tester to such descriptions. Even if truly the music such as Handel’s ‘Messiah’ (Katschner, DHM) of SACD has been leaked – by the way a recording with the eponymous instrument in the Continuo: the lute. The technician would rather attest balance, ESS and a full frequency range of the Sonus instead such whims and praise their Imaging. But it would explain adequately why the Sonus Faber in direct comparison with the 14 Nubert NuVero as well as with their own, significantly cheaper comrade toy Tower remained always the samtigere, long-more suitable and warmer box. Such a vote is often at the expense of agility and dynamics – not the case with the Liuto. If it was required, such as toto’s “hold the line” (25th anniversary concert), she put crisp bass waves and concert dynamics of the membranes, more distinctive (such as when Julianna Rayes “Slowly” from “Dominoes”, B & W Music Club), she refrained from soft and polite. In contrast to the comparison boxes by Nubert and out of the House, almost tried to peel consonants and breathy sounds from the delicate female voice with educate rigor, the Sonus concentrated on the basic sound of the beautiful jazz singer. That the massed choir sounds of Wagner’s “Lohengrin” (Bychkow, profile) over the Nubert minimally more agile and complexer sounded, taking in the face of soft clay and the Liuto fond in buying unconditional long-term fitness. With this speaker you can hear not only a few Arias, but prefer a whole Opera on the piece.
