Sonetto III G2 features a 1.1" Soft-dome Tweeter and 2 x 6.5" Paper Pulp Woofer. On the other hand, the 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.
Frequency Response
Sonetto III G2 has a frequency range of 38-40k Hz whereas Sonetto I has a frequency range of 45-25k Hz. With a minimum frequency of 38Hz, the Sonetto III G2 can go significantly deeper on the low side and provide stronger bass compared to 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 Floor-standing class in our database.
Low Frequency
Floor-standing 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 III G2 and Sonetto I have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto III G2 sensitivity is rated at 88 dB and the Sonetto I's is at 87 dB. This 1 dB difference makes the Sonus faber Sonetto III G2 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 III G2 and the Sonetto III G2 can provide this impedance level.

Floor-standing Speakers
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 III G2 can handle a max power of 280 watts RMS, whereas Sonetto I has a max power handling value of 150 watts RMS, 130 watts less than the Sonetto III G2.
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 III G2 and Sonetto I features dual binding post speaker terminals for bi-amping or bi-wiring.
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 faber Sonetto III G2's and Sonus Sonetto I's external dimensions. Sonus faber Sonetto III G2 has external dimensions of 1069.0 x 288.0 x 364.0mm (42-1/16inch x 11-5/16inch x 14-5/16inch) whereas Sonus Sonetto I has external dimensions of 359.0 x 219.0 x 305.0mm (14 x 9 x 12inch).
Sonus faber Sonetto III G2 is clearly the larger of the two speakers. Its body is 69mm wider, 710mm taller and 59mm deeper than Sonus Sonetto I.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Sonus faber Sonetto III G2 needs about 57% more floor or shelf area. Sonus faber Sonetto III G2 is 59mm deeper, so it stands that much further out from the wall. Sonus faber Sonetto III G2 is 710mm taller.
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 faber Sonetto III G2 is approximately 1048.3cm2 / 162.5inch2 and base area of the Sonus Sonetto I is approximately 668.0cm2 / 103.5inch2. The Sonetto III G2 requires 57% more surface area than the Sonetto I which gives it a small disadvantage on placement in tight spaces.
