Sonetto CI features a 1.15" high definition DAD Dome Tweeter and 2 x 6" aluminum cone Woofer with a Crossover frequency at 1.550 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 CI has a frequency range of 60-25k 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 significantly deeper on the low side and provide stronger bass compared to the Sonetto CI's min frequency of 60Hz.

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

Min
Average
Median

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 CI and Sonetto III G2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto CI sensitivity is rated at 90 dB and the Sonetto III G2's is at 88 dB. This 2 dB difference makes the Sonus Sonetto Center I 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 CI and the Sonetto CI 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 III G2 can handle a max power of 280 watts RMS, whereas Sonetto CI has a max power handling value of 200 watts RMS, 80 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.

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 I needs about 43% more floor or shelf area. Sonus faber Sonetto III G2 is 61mm deeper, so it stands that much further out from the wall. Sonus faber Sonetto III G2 is 827mm 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 I is approximately 1499.9cm2 / 232.5inch2 and base area of the Sonus faber Sonetto III G2 is approximately 1048.3cm2 / 162.5inch2. The Sonetto CI requires 43% more surface area than the Sonetto III G2 which gives it a small disadvantage on placement in tight spaces.

Verdict

Siblings in Sonus faber's Sonetto series, so they share a family sound. It comes down to size, output and price.

AreaBetterWhy
BassBSonus faber Sonetto III G2 digs deeper - 38Hz against 60Hz.
Amplifier needsASonus Sonetto Center I is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier.
HeadroomBSonus faber Sonetto III G2 takes more power (280W vs 200W) - more in hand in a big room.
SizedependsSonus Sonetto Center I is easier to place; Sonus faber Sonetto III G2 is bigger, which usually goes with fuller bass. Your room decides.
TypedependsA Passive Center Channel against a Passive Floor-standing - a different job rather than a better one.
ExpandabilitydependsSonus Sonetto Center I: bi-amping; Sonus faber Sonetto III G2: bi-amping.
PriceASonus Sonetto Center I is cheaper - $1,099 against $5,000, about 78% less; arguably a different class.

A Sonus Sonetto Center I  B Sonus faber Sonetto III G2
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?

Sonus faber Sonetto III G2 is ahead, but only on 1 of the measured areas, and it costs about 4.5x the price. That is a lot of money for a narrow margin on paper - Sonus Sonetto Center I looks like the sensible buy unless something else about the Sonus faber Sonetto III G2 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 60Hz anyway, which makes the cheaper Sonus Sonetto Center I much easier to justify. In a large or open-plan room, Sonus faber Sonetto III G2 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Sonus Sonetto Center I is the easier speaker to get right.

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.
