History
What size room are the Sonus Lumina III and Sonus Lumina V 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

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. On the other hand, the Lumina V features a 1.15" high definition DAD Tweeter, a 6" Midrange and 2 x 6.5" paper cone Woofer with a Crossover frequency at 260 and 2600 Hz.
Frequency Response
Lumina III has a frequency range of 40-24k Hz whereas Lumina V has a frequency range of 38-24k Hz. With a minimum frequency of 38Hz, the Lumina V can go slightly deeper then the Lumina III's min frequency of 40Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Lumina III and Lumina V have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina III sensitivity is rated at 89 dB and the Lumina V's is at 90 dB. This 1 dB difference makes the Sonus Lumina V a more sensitive speaker compared to Sonus Lumina III, 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 Lumina III and the Lumina III can provide this impedance level.
Sensitivity
Floor-standing Speakers
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.
Lumina V can handle a max power of 300 watts RMS, whereas Lumina III has a max power handling value of 250 watts RMS, 50 watts less than the Lumina V.
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 Lumina III and Lumina V features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Lumina III and Lumina V have bottom firing ports.
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 Lumina III's and Sonus Lumina V's external dimensions. Sonus Lumina III has external dimensions of 989.0 x 228.0 x 278.0mm (38.9 x 9 x 10.9inch) whereas Sonus Lumina V has external dimensions of 1049.0 x 280.0 x 373.0mm (41.3 x 11 x 14.7inch).
Sonus Lumina V is clearly the larger of the two speakers. Its body is 52mm wider, 60mm taller and 95mm deeper than Sonus Lumina III.
Below you can see the front view size comparison of Sonus Lumina III and Sonus Lumina V in scale.

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 Lumina III is approximately 633.8cm2 / 98.2inch2 and base area of the Sonus Lumina V is approximately 1044.4cm2 / 161.9inch2. The Lumina III requires 39% less surface area than the Lumina V which gives it a small advantage 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 Lumina III weighs 15.90kg / 35lbs and the Sonus Lumina V weighs 22.50kg / 49.5lbs. This makes the Lumina V 42% heavier than the Lumina III.
Here is a comparison of how Lumina III and Lumina V's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Sonus faber's Lumina series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (40Hz vs 38Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 90dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (250W vs 300W). |
| Size | depends | Sonus Lumina III is easier to place; Sonus Lumina V is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Sonus Lumina III: bi-amping; Sonus Lumina V: bi-amping. |
| Price | A | Sonus Lumina III is cheaper - $2,199 against $2,799, about 21% less. |
A Sonus Lumina III B Sonus Lumina V
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. In a large or open-plan room, Sonus Lumina V has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Sonus Lumina III 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.
