The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Sonetto II and Lumina II are 2-way speakers.

Sonetto II features a 1.15" high definition DAD Dome Tweeter and 1 x 6.5" cellulose pulp and other natural fibers Woofer with a Crossover frequency at 2650 Hz. On the other hand, the Lumina II features a 1.15" high definition DAD Tweeter and 1 x 6" paper cone Woofer with a Crossover frequency at 1800Hz.
Frequency Response
Sonetto II has a frequency range of 42-25k Hz whereas Lumina II has a frequency range of 55-24k Hz. With a minimum frequency of 42Hz, the Sonetto II can go significantly deeper on the low side and provide stronger bass compared to the Lumina II's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Sonetto II and Lumina II have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto II sensitivity is rated at 87 dB and the Lumina II's is at 86 dB. This 1 dB difference makes the Sonus Sonetto II a more sensitive speaker compared to Sonus Lumina II, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Sonetto II and the Sonetto II can provide this impedance level.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Sonetto II can handle a max power of 200 watts RMS, whereas Lumina II has a max power handling value of 150 watts RMS, 50 watts less than the Sonetto II.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Sonetto II and Lumina II features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Lumina II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Sonetto II and Lumina II have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Sonus Sonetto II's and Sonus Lumina II's external dimensions. Sonus Sonetto II has external dimensions of 370.0 x 250.0 x 334.0mm (15 x 10 x 13inch) whereas Sonus Lumina II has external dimensions of 304.0 x 180.0 x 263.0mm (12 x 7.1 x 10.3inch).
Sonus Sonetto II is clearly the larger of the two speakers. Its body is 70mm wider, 66mm taller and 71mm deeper than Sonus Lumina II.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Sonus Sonetto II needs about 76% more floor or shelf area. Sonus Sonetto II is 71mm deeper, so it stands that much further out from the wall. Sonus Sonetto II is 66mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Sonus Sonetto II is approximately 835.0cm2 / 129.4inch2 and base area of the Sonus Lumina II is approximately 473.4cm2 / 73.4inch2. The Sonetto II requires 76% more surface area than the Lumina II which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Sonus Sonetto II weighs 6.80kg / 15lbs and the Sonus Lumina II weighs 5.65kg / 12.4lbs. This makes the Sonetto II 20% heavier than the Lumina II.
Here is a comparison of how Sonetto II and Lumina II's weights compare with the average, max and min weights in Passive Bookshelf class.

Both are Sonus faber, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | A | Sonus Sonetto II digs deeper - 42Hz against 55Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 86dB) - both want much the same power. |
| Headroom | A | Sonus Sonetto II takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Sonus Lumina II is easier to place; Sonus Sonetto II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Sonus Sonetto II: bi-amping; Sonus Lumina II: bi-amping. Sonus Sonetto II sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | B | Sonus Lumina II is cheaper - $1,199 against $1,499, about 20% less. |
A Sonus Sonetto II B Sonus Lumina II
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Sonus Sonetto II measures better, Sonus Lumina II costs about about 25% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, which makes the cheaper Sonus Lumina II much easier to justify. In a large or open-plan room, Sonus Sonetto II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Sonus Lumina II is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
