Drivers
One of the fundamental differences between these two speakers is that Sonetto I is a 2-way design whereas the Sonetto V is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Sonetto I features a 1.15" high definition DAD Dome Tweeter and 1 x 6" cellulose pulp and other natural fibers Woofer with a Crossover frequency at 2500 Hz. On the other hand, the 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.
Frequency Response
Sonetto I has a frequency range of 45-25k Hz whereas Sonetto V has a frequency range of 38-25k Hz. With a minimum frequency of 38Hz, the Sonetto V can go significantly deeper on the low side and provide stronger bass compared to the Sonetto I's min frequency of 45Hz.
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 Bookshelf class in our database.
Low Frequency

High Frequency
Bookshelf 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 I and Sonetto V have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto I sensitivity is rated at 87 dB and the Sonetto V's is at 90 dB. This 3 dB difference makes the Sonus Sonetto V a more sensitive speaker compared to Sonus Sonetto I, 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 I and the Sonetto I 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 I can handle a max power of 300 watts RMS from the amp the whereas Sonetto I has a max power handling value of 150 watts RMS , 150 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 I and Sonetto V 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
Cabinet Type and Port Position
Sonetto I has a front firing port whereas Sonetto V has a bottom firing ports. Sonus Sonetto I's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Sonus Sonetto V with its rear-firing port.
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 I's and Sonus Sonetto V's external dimensions. Sonus Sonetto I has external dimensions of 359.0 x 219.0 x 305.0mm ( 14 x 9 x 12inch) whereas Sonus Sonetto V has external dimensions of 1072.0 x 258.0 x 409.0mm ( 42 x 10 x 16inch) .
Sonus Sonetto V is clearly the larger of the two speakers. Its body is 39mm wider, 713mm taller and 104mm deeper than Sonus Sonetto I.
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 I is approximately 668.0cm2 / 103.5inch2 and base area of the Sonus Sonetto V is approximately 1055.2cm2 / 163.6inch2. The Sonetto I requires 37% less surface area than the Sonetto V which gives it a small advantage on placement in tight spaces.
