In this review, we will be comparing two different type of speakers by Sonus Faber. Sonus Faber Lumina I is a Bookshelf speaker whereas the Lumina CI is a Center Channel speaker.
Let's have a brief look at the main features
of Sonus Lumina I and Sonus Lumina Center I first before getting into our more
detailed comparison.
Lumina I and Lumina CI are members of Sonus Faber's Lumina series of speakers. Below you can find the loudspeakers from this series.

Lumina I features a 1.15" high definition DAD Tweeter and 1 x 4.75" paper cone Woofer with a Crossover frequency at 2000Hz. On the other hand, the Lumina CI features a 1.15" high definition DAD Tweeter and 2 x 4.75" paper cone Woofer with a Crossover frequency at 2000 Hz.
Frequency Response
Lumina I and Lumina CI has exactly the same frequency range of 65-24k Hz.
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 Bookshelf class in our database.

High Frequency

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
Lumina I and Lumina CI have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina I sensitivity is rated at 88 dB and the Lumina CI's is at 87 dB. This 3 dB difference makes the Sonus Lumina Center I a more sensitive speaker compared to Sonus Lumina 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 Lumina I and the Lumina I 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.
Lumina I and Lumina CI has the same power range of 30-100 watts.
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 Lumina I and Lumina CI features dual binding post speaker terminals for bi-amping or bi-wiring.
Sonus Lumina I's Binding post terminals allows Bi-amping or bi-wiring
Sonus Lumina Center I's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Lumina I and Lumina CI 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
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 Lumina I's and Sonus Lumina Center I's external dimensions. Sonus Lumina I has external dimensions of 280.0 x 148.0 x 213.0mm ( 11 x 5.8 x 8.4inch) whereas Sonus Lumina Center I has external dimensions of 169.0 x 524.0 x 213.0mm ( 6.6 x 20.6 x 8.4inch) .
Below you can see the front view size comparison of Sonus Lumina I and Sonus Lumina Center I in scale.

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 Lumina I is approximately 315.2cm2 / 48.9inch2 and base area of the Sonus Lumina Center I is approximately 1116.1cm2 / 173.0inch2. The Lumina I requires 72% less surface area than the Lumina CI which gives it a small advantage on placement in tight spaces.
