History
What size room are the Sonus Lumina V 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:

400 sq. ft / 36 m2.
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.)
In the following sections, we will get into more detail in order to better understand how the Sonus Lumina V 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.

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. 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
Lumina V has a frequency range of 38-24k Hz whereas Lumina III has a frequency range of 40-24k Hz. With a minimum frequency of 38Hz, the Lumina V can go slightly deeper then the Lumina III's min frequency of 40Hz.
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.
Low Frequency
Floor-standing Speakers
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
Lumina V and Lumina III have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina V sensitivity is rated at 90 dB and the Lumina III's is at 89 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 V and the Lumina V 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.
Lumina V can handle a max power of 300 watts RMS from the amp the whereas Lumina III has a max power handling value of 250 watts RMS, 50 watts less than the Lumina V.
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 Lumina V and Lumina III features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Lumina V 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 Lumina V's and Sonus Lumina III's external dimensions. Sonus Lumina V has external dimensions of 1049.0 x 280.0 x 373.0mm ( 41.3 x 11 x 14.7inch) 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 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 V and Sonus Lumina III 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 V is approximately 1044.4cm2 / 161.9inch2 and base area of the Sonus Lumina III is approximately 633.8cm2 / 98.2inch2. The Lumina V requires 65% 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 Lumina V weighs 22.50kg / 49.5lbs and the Sonus Lumina III weighs 15.90kg / 35lbs. This makes the Lumina V 42% heavier than the Lumina III.
Here is a comparison of how Lumina V and Lumina III's weights compare with the average, max and min weights in Passive Floor-standing class.
