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 S400 MKII features a 0.74" fine weave soft fabric textile aluminum waveguide Tweeter and 1 x 6" paper Woofer with a Crossover frequency at 1800Hz.
Frequency Response
Sonetto II has a frequency range of 42-25k Hz whereas S400 MKII has a frequency range of 33-40k HZ. With a minimum frequency of 33Hz, the S400 MKII can go significantly deeper on the low side and provide stronger bass compared to 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.

High Frequency

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 S400 MKII 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 S400 MKII's is at 88 dB. This 1 dB difference makes the Buchardt S400 MKII 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 and S400 MKII has the same power range of 40-200 watts.
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.
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 Buchardt S400 MKII's external dimensions. Sonus Sonetto II has external dimensions of 370.0 x 250.0 x 334.0mm ( 15 x 10 x 13inch) whereas Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) .
Sonus Sonetto II is clearly the larger of the two speakers. Its body is 70mm wider, 5mm taller and 54mm deeper than Buchardt S400 MKII.
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 Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2. The Sonetto II requires 66% more surface area than the S400 MKII 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 II weighs 6.80kg / 15lbs and the Buchardt S400 MKII weighs 7.50kg / 16.5lbs. This makes the S400 MKII 10% heavier than the Sonetto II.
Here is a comparison of how Sonetto II and S400 MKII's weights compare with the average, max and min weights in Passive Bookshelf class.
