In this review, we will be comparing Sonetto III and Lumina III, two Passive Floor-standing speakers by Sonus Faber Let's have a brief look at the main features
of Sonus Sonetto III and Sonus Lumina III first before getting into our more
detailed comparison.
What size room are the Sonus Sonetto III and Sonus Lumina III speakers good for?
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:
In the following sections, we will get into more detail in order to better understand how the Sonus Sonetto III and Sonus Lumina III compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Sonetto III features a 1.15" high definition DAD Dome Tweeter , a 6" Midrange and 2 x 6" aluminum cone Woofer with a Crossover frequency at 220 and 3.250 Hz. On the other hand, the Lumina III features a 1.15" high definition DAD Tweeter , a 6" Midrange and 2 x 6" paper cone Woofer with a Crossover frequency at 350 and 3500 Hz.
Frequency Response
Sonetto III has a frequency range of 42-25k Hz whereas Lumina III has a frequency range of 40-24k Hz. With a minimum frequency of 40Hz, the Lumina III can go slightly deeper then the Sonetto III's min frequency of 42Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

High Frequency
Floor-standing Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Sonetto III and Lumina III have the same Impedance of 4 ohms and their sensitivity is also same at 89 dB.
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 III and the Sonetto III can provide this impedance level.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Sonetto III and Lumina III has the same power range of 50-250 watts.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both Sonetto III and Lumina III features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Sonetto III's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Sonetto III and Lumina III have bottom firing ports.
Physical Specs
Size of a speaker can sometimes become 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 III's and Sonus Lumina III's external dimensions. Sonus Sonetto III has external dimensions of 1018.0 x 219.0 x 305.0mm ( 40 x 9 x 12inch) whereas Sonus Lumina III has external dimensions of 989.0 x 228.0 x 278.0mm ( 38.9 x 9 x 10.9inch) .
Sonus Lumina III is 29mm shorter and 27mm less deeper than Sonus Sonetto III but it is also 9mm wider.
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 III is approximately 668.0cm2 / 103.5inch2 and base area of the Sonus Lumina III is approximately 633.8cm2 / 98.2inch2. The Sonetto III requires 5% more surface area than the Lumina III 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 III weighs 16.00kg / 35.2lbs and the Sonus Lumina III weighs 15.90kg / 35lbs. This makes the Sonetto III 1% heavier than the Lumina III.
Here is a comparison of how Sonetto III and Lumina III's weights compare with the average, max and min weights in Passive Floor-standing class.
