Drivers
One of the fundamental differences between these two speakers is that Sonetto II is a 2-way design whereas the Lumina 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 II features a 1.15" high definition DAD Dome Tweeter and 1 x 6.5" cellulose pulp and other natural fibers Woofer with a Crossover frequency at 2650 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
Sonetto II has a frequency range of 42-25k 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 Sonetto II'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 Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
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 II and Lumina V have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto II sensitivity is rated at 87 dB and the Lumina V's is at 90 dB. This 3 dB difference makes the Sonus Lumina V a more sensitive speaker compared to Sonus Sonetto II, 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 II and the Sonetto II 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 II can handle a max power of 300 watts RMS from the amp the whereas Sonetto II has a max power handling value of 200 watts RMS , 100 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 Sonetto II and Lumina V features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Sonetto II has a front firing port whereas Lumina V has a bottom firing ports. Sonus Sonetto II's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Sonus Lumina 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 II's and Sonus Lumina V's external dimensions. Sonus Sonetto II has external dimensions of 370.0 x 250.0 x 334.0mm ( 15 x 10 x 13inch) 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 30mm wider, 679mm taller and 39mm deeper than Sonus Sonetto II.
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 II is approximately 835.0cm2 / 129.4inch2 and base area of the Sonus Lumina V is approximately 1044.4cm2 / 161.9inch2. The Sonetto II requires 20% less surface area than the Lumina V which gives it a small advantage on placement in tight spaces.
