Lumina CI and Lumina V Amator are members of Sonus faber's Lumina 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 Lumina CI is a 2-way design whereas the Lumina V Amator 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.

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 V Amator features a 1.125" Soft-Dome Tweeter, a 6.0" Midrange and 2 x 6.5" Cellulose Pulp Woofer.
Frequency Response
Lumina CI has a frequency range of 65-24k Hz whereas Lumina V Amator has a frequency range of 38-24k Hz. With a minimum frequency of 38Hz, the Lumina V Amator can go significantly deeper on the low side and provide stronger bass compared to the Lumina CI's min frequency of 65Hz.
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
Lumina CI and Lumina V Amator 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 V Amator's is at 90 dB. This 3 dB difference makes the Sonus faber Lumina V Amator a more sensitive speaker compared to Sonus Lumina 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 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Lumina V Amator can handle a max power of 300 watts RMS, whereas Lumina CI has a max power handling value of 100 watts RMS, 200 watts less than the Lumina V Amator.
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 Lumina Center I's and Sonus faber Lumina V Amator'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 faber Lumina V Amator has external dimensions of 1050.0 x 280.0 x 375.0mm (41-5/16inch x 11inch x 14-3/4inch).
Sonus Lumina Center I is 881mm shorter and 162mm less deeper than Sonus faber Lumina V Amator but it is also 244mm wider.
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.
Near-identical footprints. Sonus faber Lumina V Amator is 162mm deeper, so it stands that much further out from the wall. Sonus faber Lumina V Amator is 881mm 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 Lumina Center I is approximately 1116.1cm2 / 173.0inch2 and base area of the Sonus faber Lumina V Amator is approximately 1050.0cm2 / 162.8inch2. The Lumina CI requires 6% more surface area than the Lumina V Amator which gives it a small disadvantage on placement in tight spaces.
