SONUS FABER LUMINA III DRIVERS
This hands over to a 150mm mid/ bass driver, which looks to have more in common with the bass drivers of the Lumina III – which are bespoke to the Lumina – than the midrange unit, which is also shared with the Sonetto. As with many modern designs, this tweeter is responsible for a huge proportion of the frequency response, with the crossover being set at 1.8kHz. The tweeter itself is mounted in a shallow waveguide to further help with distortion. The company says that this helps to control the break-up characteristics of the dome and improves dispersion. Key to how this functions is the framework that Sonus faber calls Damped Apex Dome (DAD) that extends over the dome itself. Give them a bit of room to breathe and a system that plays to their strengths, and you’ll be treated to a wonderfully musical experience.This means that it uses the same 29mm soft dome tweeter as the rest of the range and indeed the Sonetto range above it. They have an unusual blend of abilities that puts them up with the best at this price. The Lumina V are thoroughly charming speakers. Rivals such as the Spendor A4 or ProAc Response DT8 are certainly more precise in the way they outline instruments and voices, and particularly bass notes, but the Sonus Fabers’ natural sonic grace and easy-going nature balance the scale. Tonally, these speakers fall on the richer, full-bodied side of neutral, but never err so far as to sound less than articulate. Yet, despite the obvious muscularity on offer, there is still enough space to deliver dynamic nuances and low-level subtleties properly.

Large-scale dynamics come through with verve and composure, with little sense of the speakers hardening up, even at higher volume levels. Those two bass drivers generate an admirable amount of low-end heft and combine that with enough agility to avoid dragging the pace of the music. We play Holst’s Jupiter and they render the classical piece with all the scale and majesty it deserves. The Lumina V have no difficulty in delivering sonic fireworks when the music demands. Sure, the piano in the track is reproduced with finesse, and the bass has authority, but these speakers are more concerned with trying to integrate these elements into a cohesive and musical whole rather than trying to dazzle us with their abilities. Similarly, we listen to Cave’s Into My Arms and it is the emotional impact of this heartfelt love song that takes priority. While we can pick out low-level details if we want to, or take apart the production with ease, these things aren’t as interesting to the Sonus Fabers as making sure the energy of Kiwanuka’s You Ain’t the Problem is communicated properly. Vocalists such as Michael Kiwanuka or Nick Cave come through with grit and passion intact the Lumina V manages to deliver voices with rare palpability. It is as articulate and expressive as we’ve heard at this level. But, given a bit of time, they begin to work their way into our affections. They’re not as forward, direct or overtly exciting as some rivals. These Sonus Fabers prove to be something of a slow burner for us.
