History
What size room are the Sonus Sonetto Center I and Sonus Sonetto Center 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:

400 sq. ft / 36 m2.
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.)
In the following sections, we will get into more detail in order to better understand how the Sonus Sonetto Center I and Sonus Sonetto Center II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Sonetto CI is a 2-way design whereas the Sonetto CII is a 3-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 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 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.
Frequency Response
Sonetto CI has a frequency range of 60-25k Hz whereas Sonetto CII has a frequency range of 42-25k Hz. With a minimum frequency of 42Hz, the Sonetto CII can go significantly deeper on the low side and provide stronger bass compared to the Sonetto CI's min frequency of 60Hz.
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 Center Channel class in our database.

High Frequency
Center Channel Speakers
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 CI and Sonetto CII 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 CII's is at 91 dB. This 1 dB difference makes the Sonus Sonetto Center II a more sensitive speaker compared to Sonus Sonetto Center 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 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. 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 CI can handle a max power of 300 watts RMS from the amp the whereas Sonetto CI has a max power handling value of 200 watts RMS , 100 watts less than the Sonetto CII.
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 CI and Sonetto CII features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Sonetto Center I's Binding post terminals allows Bi-amping or bi-wiring
Sonus Sonetto Center II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Sonetto CI and Sonetto CII have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Center I's and Sonus Sonetto Center II's external dimensions. Sonus Sonetto Center I has external dimensions of 242.0 x 495.0 x 303.0mm ( 10 x 20 x 12inch) whereas Sonus Sonetto Center II has external dimensions of 289.0 x 743.0 x 409.0mm ( 12 x 30 x 16inch) .
Sonus Sonetto Center II is clearly the larger of the two speakers. Its body is 248mm wider, 47mm taller and 106mm deeper than Sonus Sonetto Center 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 Center I is approximately 1499.9cm2 / 232.5inch2 and base area of the Sonus Sonetto Center II is approximately 3038.9cm2 / 471.0inch2. The Sonetto CI requires 51% less surface area than the Sonetto CII 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 Center I weighs 6.50kg / 14.3lbs and the Sonus Sonetto Center II weighs 16.20kg / 35.6lbs. This makes the Sonetto CII 149% heavier than the Sonetto CI.
Here is a comparison of how Sonetto CI and Sonetto CII's weights compare with the average, max and min weights in Passive Center Channel class.
