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. On the other hand, the Lumina II features a 1.15" high definition DAD Tweeter and 1 x 6" paper cone Woofer with a Crossover frequency at 1800Hz.
Frequency Response
Lumina CI has a frequency range of 65-24k Hz whereas Lumina II has a frequency range of 55-24k Hz. With a minimum frequency of 55Hz, the Lumina II can go significantly deeper on the low side and provide stronger bass compared to the Lumina CI's min frequency of 65Hz.
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
Lumina CI and Lumina II have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Lumina CI sensitivity is rated at 87 dB and the Lumina II's is at 86 dB. This 1 dB difference makes the Sonus Lumina Center I a more sensitive speaker compared to Sonus Lumina II, 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 CI and the Lumina 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.
Lumina CI can handle a max power of 150 watts RMS from the amp the whereas Lumina CI has a max power handling value of 100 watts RMS , 50 watts less than the Lumina II.
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 CI and Lumina II features dual binding post speaker terminals for bi-amping or bi-wiring.

Cabinet Type and Port Position
Both Lumina CI and Lumina II 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 Center I's and Sonus Lumina II's external dimensions. Sonus Lumina Center I has external dimensions of 169.0 x 524.0 x 213.0mm ( 6.6 x 20.6 x 8.4inch) whereas Sonus Lumina II has external dimensions of 304.0 x 180.0 x 263.0mm ( 12 x 7.1 x 10.3inch) .
Sonus Lumina Center I is 135mm shorter and 50mm less deeper than Sonus Lumina II but it is also 344mm wider.
Below you can see the front view size comparison of Sonus Lumina Center I and Sonus Lumina II 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 Center I is approximately 1116.1cm2 / 173.0inch2 and base area of the Sonus Lumina II is approximately 473.4cm2 / 73.4inch2. The Lumina CI requires 136% more surface area than the Lumina II which gives it a small disadvantage on placement in tight spaces.
