History
What size room are the Sonus Sonetto III and Sonus Sonetto VIII 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.)
In the following sections, we will get into more detail in order to better understand how the Sonus Sonetto III and Sonus Sonetto VIII 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 Sonetto VIII features a 1.15" high definition DAD Dome Tweeter , a 6" Midrange and 3 x 7" aluminum cone Woofer with a Crossover frequency at 270 and 3.000 Hz.
Frequency Response
Sonetto III has a frequency range of 42-25k Hz whereas Sonetto VIII has a frequency range of 36-25k Hz. With a minimum frequency of 36Hz, the Sonetto VIII can go significantly deeper on the low side and provide stronger bass compared to 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 Sonetto VIII have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto III sensitivity is rated at 89 dB and the Sonetto VIII's is at 90 dB. This 1 dB difference makes the Sonus Sonetto VIII 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 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 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 VIII.
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 Sonetto VIII 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
Sonus Sonetto VIII's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Sonetto III and Sonetto VIII 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 Sonetto VIII'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 Sonetto VIII has external dimensions of 1188.0 x 283.0 x 427.0mm ( 47 x 11 x 17inch) .
Sonus Sonetto VIII is clearly the larger of the two speakers. Its body is 64mm wider, 170mm taller and 122mm 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 III is approximately 668.0cm2 / 103.5inch2 and base area of the Sonus Sonetto VIII is approximately 1208.4cm2 / 187.3inch2. The Sonetto III requires 45% less surface area than the Sonetto VIII 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 Sonetto III weighs 16.00kg / 35.2lbs and the Sonus Sonetto VIII weighs 26.30kg / 57.9lbs. This makes the Sonetto VIII 64% heavier than the Sonetto III.
Here is a comparison of how Sonetto III and Sonetto VIII's weights compare with the average, max and min weights in Passive Floor-standing class.
