History
What size room are the Sonus Sonetto V and Sonus Sonetto 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 Sonetto V and Sonus Sonetto III compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Sonetto V features a 1.15" high definition DAD Dome Tweeter , a 6" Midrange and 2 x 7" aluminum cone Woofer with a Crossover frequency at 235 and 3.000 Hz. On the other hand, the 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.
Frequency Response
Sonetto V has a frequency range of 38-25k Hz whereas Sonetto III has a frequency range of 42-25k Hz. With a minimum frequency of 38Hz, the Sonetto V 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 V and Sonetto III have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto V sensitivity is rated at 90 dB and the Sonetto III's is at 89 dB. This 1 dB difference makes the Sonus Sonetto V a more sensitive speaker compared to Sonus Sonetto 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 Sonetto V and the Sonetto 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.
Sonetto V can handle a max power of 300 watts RMS from the amp the whereas Sonetto III has a max power handling value of 250 watts RMS, 50 watts less than the Sonetto 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 Sonetto V and Sonetto III features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Sonetto V's Binding post terminals allows 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 V and Sonetto 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 V's and Sonus Sonetto III's external dimensions. Sonus Sonetto V has external dimensions of 1072.0 x 258.0 x 409.0mm ( 42 x 10 x 16inch) whereas Sonus Sonetto III has external dimensions of 1018.0 x 219.0 x 305.0mm ( 40 x 9 x 12inch) .
Sonus Sonetto V is clearly the larger of the two speakers. Its body is 39mm wider, 54mm taller and 104mm deeper than Sonus Sonetto III.
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 V is approximately 1055.2cm2 / 163.6inch2 and base area of the Sonus Sonetto III is approximately 668.0cm2 / 103.5inch2. The Sonetto V requires 58% more surface area than the Sonetto 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 V weighs 22.60kg / 49.7lbs and the Sonus Sonetto III weighs 16.00kg / 35.2lbs. This makes the Sonetto V 41% heavier than the Sonetto III.
Here is a comparison of how Sonetto V and Sonetto III's weights compare with the average, max and min weights in Passive Floor-standing class.
