History
What size room are the Sonus Sonetto I and Sonus Sonetto II 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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

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 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.
Frequency Response
Sonetto I has a frequency range of 45-25k Hz whereas Sonetto II has a frequency range of 42-25k Hz. With a minimum frequency of 42Hz, the Sonetto II can go slightly deeper then the Sonetto I's min frequency of 45Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Sonetto I and Sonetto II have the same Impedance of 4 ohms and their sensitivity is also same at 87 dB.
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.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Sonetto II can handle a max power of 200 watts RMS, whereas Sonetto I has a max power handling value of 150 watts RMS, 50 watts less than the Sonetto II.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Sonetto I and Sonetto II features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Sonetto I and Sonetto II have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
Physical Specs
The size of a speaker can sometimes be 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 II'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 II has external dimensions of 370.0 x 250.0 x 334.0mm (15 x 10 x 13inch).
Sonus Sonetto II is clearly the larger of the two speakers. Its body is 31mm wider, 11mm taller and 29mm 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 II is approximately 835.0cm2 / 129.4inch2. The Sonetto I requires 20% less surface area than the Sonetto II 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 I weighs 5.50kg / 12.1lbs and the Sonus Sonetto II weighs 6.80kg / 15lbs. This makes the Sonetto II 24% heavier than the Sonetto I.
Here is a comparison of how Sonetto I and Sonetto II's weights compare with the average, max and min weights in Passive Bookshelf class.

Siblings in Sonus faber's Sonetto series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Sonus Sonetto II digs deeper - 42Hz against 45Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 87dB) - both want much the same power. |
| Headroom | B | Sonus Sonetto II takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Sonus Sonetto I is easier to place; Sonus Sonetto II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Sonus Sonetto I: bi-amping; Sonus Sonetto II: bi-amping. |
| Price | A | Sonus Sonetto I is cheaper - $1,099 against $1,499, about 27% less. |
A Sonus Sonetto I B Sonus Sonetto II
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Sonus Sonetto II measures better, Sonus Sonetto I costs about about 36% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. Think about the whole system, not just the speakers: the roughly $400 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
