The Sonus faber Lumina II is a very different object from the active wireless systems elsewhere in this series. It is a passive two-way bookshelf speaker: no streaming platform, no built-in amplifier, no room-correction microphone and no app. That sounds less convenient, but the simplicity is part of the appeal. The Lumina II gives you a beautifully made loudspeaker that can remain useful while amplifiers, streamers and digital formats change around it.

For design-conscious listeners, the Italian presentation matters almost as much as the technical specification. Sonus faber uses a multilayer wood front baffle, real wood veneer options and black leather wrapping across the cabinet. The result feels closer to furniture craft than to ordinary black-box hi-fi.

This review combines Sonus faber's current specifications with independent listening assessments and practical system-building advice. It is an editorial ownership guide rather than a claim of private laboratory measurement by THE LUXE JOURNAL.

What the Lumina II Is

The Lumina II is a two-way vented bookshelf loudspeaker. It uses a 29mm Damped Apex Dome soft-dome tweeter and a 150mm paper-cone midwoofer. The crossover point is 1.8kHz.

Sonus faber quotes a frequency response of 55Hz to 24kHz, sensitivity of 86dB SPL at 2.83V/1m and a nominal impedance of 4 ohms. Recommended amplifier power is 30 to 150 watts per channel with an undistorted signal.

Each speaker measures roughly 304mm high, 180mm wide and 263mm deep, and weighs about 5.8kg. That makes the Lumina II genuinely compact, but not a lightweight lifestyle speaker.

Design and Materials

The strongest visual detail is the front baffle. Depending on finish, the speaker can combine walnut, wenge or piano-black surfaces with maple inlays, while the top and sides are wrapped in black leather.

That mix gives the Lumina II an unusually domestic appearance. It works in warm modern interiors, libraries, studies, bedrooms and living rooms where a hard-edged studio monitor would feel too technical.

The proportions are also easy to style. On elegant stands, the speaker reads like a small piece of furniture rather than a machine. The cabinet is narrow enough to sit beside a console or bookcase without dominating the room.

Front-Firing Reflex Port: A Practical Advantage

Sonus faber places the reflex port on the front. The company specifically says this makes the Lumina II less sensitive to positioning close to a back wall.

That does not mean you should push the speaker into a corner. All loudspeakers interact with room boundaries. But compared with a rear-ported design, the Lumina II gives you more flexibility in apartments and shallower rooms.

Start with the speakers on stands, slightly away from the wall, then move them closer in small steps until bass weight and image depth feel balanced.

Amplifier Matching Matters

At 86dB sensitivity and 4-ohm nominal impedance, the Lumina II is not exceptionally efficient. It deserves a capable amplifier with good current delivery rather than the cheapest compact amp available.

Sonus faber's recommended range of 30 to 150 watts is broad. For a small room and moderate listening level, a quality 40- to 60-watt amplifier can work very well. For a larger room or more demanding music, extra power and control are useful.

The key is quality, not simply the biggest watt number. A well-designed integrated amplifier from Naim, Hegel, Rotel, Marantz, Rega, Cambridge Audio or similar brands can form a strong system depending on budget and tonal preference.

Sound Character: Natural, Open and Refined

Independent listening reviews have consistently described the Lumina II as open, detailed and natural, with a presentation that fits Sonus faber's reputation for musical smoothness.

The tweeter avoids the exaggerated sparkle that can make some compact speakers sound exciting for ten minutes and tiring after an hour. Vocals and acoustic instruments are the main attraction. Strings, piano and voices have texture and body rather than sounding sharply outlined.

That makes the Lumina II especially strong for jazz, classical, singer-songwriter material, vocal pop and acoustic recordings.

It is not a dull speaker. Detail is present, but the overall balance leans toward refinement rather than aggressive analysis.

Bass: The Main Limitation

The official response begins at 55Hz, and independent testing has highlighted that deep bass is the main limitation. The Lumina II can produce useful mid-bass and enough weight for normal listening, but it does not have the low-frequency authority of a larger floorstander.

On acoustic bass, drums and most pop music, the presentation remains convincing. On deep electronic bass, organ, large orchestral scale or cinema effects, the missing bottom octave becomes easier to notice.

This is where system planning matters. In a small room, the limited low bass can actually be an advantage because it reduces the risk of boom. In a larger living room, a carefully integrated subwoofer can transform the system without replacing the speakers.

Stereo Imaging and Placement

A passive stereo pair gives you more placement freedom than a one-box system. Put the Lumina IIs on stable stands, create a symmetrical listening triangle and experiment with toe-in.

Because the speaker has a conventional tweeter-above-woofer layout, aiming the speakers slightly toward the listener can help focus the centre image. Do not assume maximum toe-in is best. Small changes alter treble balance and soundstage width.

Keep both speakers at the same height and distance from the listening position. If one sits next to a glass wall and the other next to heavy curtains, the room will sound asymmetrical even if the speakers are perfectly measured.

Do They Belong on Bookshelves?

The product category says bookshelf, but "standmount" is the more useful mental model. Sonus faber notes that Lumina II can work in shelving, and the front port helps, but a dedicated stand normally gives you better freedom to optimise height, distance and toe-in.

If you use a shelf, keep the speaker close to the front edge rather than deep inside a cubby. Leave space around the cabinet and use isolation pads if the shelf resonates.

The ideal luxury setup is still a pair of simple stands with cable routing hidden as cleanly as possible.

System Building: Traditional Hi-Fi Without the Visual Mess

A passive system can look elegant if you resist the urge to stack equipment. One integrated amplifier with built-in streaming or a compact streamer/amplifier is enough for most homes.

Place the amplifier on a low sideboard, keep speaker cables the same practical length and route them along skirting or through discreet channels. If you are renovating, pre-wire speaker cable inside conduit so it can be replaced later.

The Lumina II pairs especially well visually with walnut, leather, travertine, bronze, dark lacquer and books. It also fits naturally into New Chinese and modern European interiors because its materials already feel warm and crafted.

Television Use

Unlike the KEF LS50 Wireless II, the Lumina II has no HDMI input because it is passive. Television integration depends entirely on the amplifier.

Choose an integrated amp or streaming amp with HDMI ARC/eARC or optical input if you want the speakers to handle TV sound. A good stereo amplifier can make dialogue and music far more natural than television speakers, but you will not get a dedicated centre channel.

For viewers who care more about music than surround effects, that trade-off can be sensible.

Who Should Buy the Lumina II?

It is ideal for listeners who want a beautiful passive speaker, prefer to choose their own amplifier and value long-term upgrade flexibility.

It suits smaller and medium rooms, music-first systems, design-conscious studies and living rooms where the speakers need to feel like part of the furniture.

It is also a strong entry into Sonus faber for people who admire the brand's higher-end Italian speakers but do not want the scale or cost of a floorstanding model.

Who Should Avoid It?

Avoid it if you want a single-box solution with no amplifier decisions. The KEF LS50 Wireless II or Naim Mu-so 2 is simpler.

Also avoid it if deep bass is your highest priority and you refuse to add a subwoofer. A larger speaker will provide more physical low-end scale.

If you listen very loudly in a large open-plan room, the Lumina II may also be smaller than the space deserves.

Styling the Lumina II

Give the wood and leather enough light to be seen. A warm lamp nearby can bring out veneer depth without shining directly on the drivers.

Use stands that are visually quiet. Black stands almost disappear; timber stands can work if their tone does not clash with the front baffle. Keep the area between the speakers low and simple.

A turntable, integrated amplifier, record storage and one sculptural vase can create a listening corner that looks intentional even when no music is playing.

Verdict

The Sonus faber Lumina II succeeds because it does not try to be everything. It is not a streamer, TV hub or smart speaker. It is a compact passive loudspeaker built around traditional stereo, tactile materials and a refined sound balance.

Its strengths are natural midrange, open detail, beautiful construction and placement flexibility from the front reflex port. Its weakness is deep bass, which is predictable for the cabinet size.

For a small or medium room, paired with a capable amplifier, that trade-off is easy to accept. The Lumina II offers something active systems cannot fully replicate: a speaker you can keep while the rest of your system evolves around it.

FAQ

How powerful should my amplifier be?

Sonus faber recommends 30 to 150 watts per channel. Quality and current capability matter as much as the headline wattage.

Does the Lumina II need a subwoofer?

Not for every listener. In small rooms and with acoustic music, it can be satisfying alone. A subwoofer is useful for deeper electronic bass, cinema and larger rooms.

Can it sit close to a wall?

Its front reflex port makes it more tolerant of close-wall placement than many rear-ported speakers, but you should still experiment with distance for the best bass and image depth.

Is it good for vinyl?

Yes. Its smooth, natural presentation suits vinyl very well, provided the amplifier includes or is paired with a suitable phono stage.

Can I use it for home cinema?

Yes, especially as front or rear channels in a Sonus faber-based system. For stereo TV use, your amplifier needs the appropriate TV input.

Is the Lumina II made in Italy?

Sonus faber positions the Lumina family around Italian design and manufacturing principles; current product materials describe the model as made in Italy.

Part 5 turns to the Naim Mu-so 2nd Generation, an all-in-one system for buyers who want the opposite philosophy: maximum integration with minimum equipment.
