Sonetto CII and Sonetto III G2 are members of Sonus faber's Sonetto series of speakers. Below you can find the loudspeakers from this series.

History
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Sonetto CII is a 3-way design whereas the Sonetto III G2 is a 2-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 CII features a 1.15" high definition DAD Dome Tweeter, a 6" Midrange and 2 x 6" aluminum cone Woofer with a Crossover frequency at 1.650 Hz. On the other hand, the Sonetto III G2 features a 1.1" Soft-dome Tweeter and 2 x 6.5" Paper Pulp Woofer.
Frequency Response
Sonetto CII has a frequency range of 42-25k Hz whereas Sonetto III G2 has a frequency range of 38-40k Hz. With a minimum frequency of 38Hz, the Sonetto III G2 can go slightly deeper then the Sonetto CII's min frequency of 42Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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 CII and Sonetto III G2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto CII sensitivity is rated at 91 dB and the Sonetto III G2's is at 88 dB. This 3 dB difference makes the Sonus Sonetto Center II a more sensitive speaker compared to Sonus faber Sonetto III G2, 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 CII and the Sonetto CII 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Sonetto CII can handle a max power of 300 watts RMS, whereas Sonetto III G2 has a max power handling value of 280 watts RMS, 20 watts less than the Sonetto CII.
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.

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 Center II's and Sonus faber Sonetto III G2's external dimensions. Sonus Sonetto Center II has external dimensions of 289.0 x 743.0 x 409.0mm (12 x 30 x 16inch) whereas 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).
Sonus faber Sonetto III G2 is 455mm narrower and 45mm less deeper than Sonus Sonetto Center II but it is also 780mm taller.
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 Sonetto Center II needs about 190% more floor or shelf area. Sonus Sonetto Center II is 45mm deeper, so it stands that much further out from the wall. Sonus faber Sonetto III G2 is 780mm 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 Sonetto Center II is approximately 3038.9cm2 / 471.0inch2 and base area of the Sonus faber Sonetto III G2 is approximately 1048.3cm2 / 162.5inch2. The Sonetto CII requires 190% more surface area than the Sonetto III G2 which gives it a small disadvantage on placement in tight spaces.
