In this review, we will be comparing Sonetto II and 606 S2 AE, two Passive Bookshelf speakers from Sonus Faber and Bowers Wilkins. Let's have a brief look at the main features
of Sonus Sonetto II and B&W 606 S2 first before getting into our more
detailed comparison.
What size room are the Sonus Sonetto II and B&W 606 S2 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:
In the following sections, we will get into more detail in order to better understand how the Sonus Sonetto II and B&W 606 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
Sonetto II has a frequency range of 42-25k Hz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 42Hz, the Sonetto II can go significantly deeper on the low side and provide stronger bass compared to the 606 S2 AE's min frequency of 52Hz.
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 is a 4 ohms speaker compared to the 606 S2 AE which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Sonetto II can provide this impedance level.
These two speakers also have different sensitivity levels. Sonetto II sensitivity is rated at 87 dB and the 606 S2 AE's is rated at 88 dB. This 1 dB difference makes the B&W 606 S2 a more sensitive speaker compared to Sonus Sonetto II, hence will play louder with the same amount of watts.

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 200 watts RMS from the amp the whereas 606 S2 AE has a max power handling value of 120 watts RMS, 80 watts less than the Sonetto II.
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 606 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 606 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Sonetto II has a front firing port whereas 606 S2 AE has a rear firing ports. Sonus Sonetto II's front-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 S2 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 B&W 606 S2's external dimensions. Sonus Sonetto II has external dimensions of 370.0 x 250.0 x 334.0mm ( 15 x 10 x 13inch) whereas B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm ( 13-5/8 x 7-1/2 x 12-13/16inch) .
Sonus Sonetto II is clearly the larger of the two speakers. Its body is 59mm wider, 23mm taller and 8mm deeper than B&W 606 S2.
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 B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The Sonetto II requires 34% more surface area than the 606 S2 AE 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 B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the 606 S2 AE 1% heavier than the Sonetto II.
Here is a comparison of how Sonetto II and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.
