History
What size room are the Sonus faber Lumina II Amator and Sonus Lumina 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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Lumina II Amator and Lumina II are 2-way speakers.

Lumina II Amator features a 1.1" Silk Soft-Dome Tweeter and 1 x 6" Paper Woofer with a Crossover frequency at 2600 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 II Amator and Lumina II has exactly the same frequency range of 55-24k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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 II Amator and Lumina II have the same Impedance of 4 ohms and their sensitivity is also same at 86 dB.
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 II Amator and the Lumina II Amator can provide this impedance level.
Sensitivity

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 II Amator and Lumina II have the same power range of 30-150 watts.
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.

Input Type and Bi-Amping / Bi-Wiring
Both Lumina II Amator and Lumina II features dual binding post speaker terminals for bi-amping or bi-wiring.

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 faber Lumina II Amator's and Sonus Lumina II's external dimensions. Sonus faber Lumina II Amator has external dimensions of 304.0 x 180.0 x 263.0mm (11-15/16 x 7-1/16 x 10-3/8inch) whereas Sonus Lumina II has external dimensions of 304.0 x 180.0 x 263.0mm (12 x 7.1 x 10.3inch).
In this case, we can see that Sonus faber Lumina II Amator and Sonus Lumina II have the exact same height, width and thickness.
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.

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 faber Lumina II Amator is approximately 473.4cm2 / 73.4inch2 and base area of the Sonus Lumina II is approximately 473.4cm2 / 73.4inch2.
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 faber Lumina II Amator weighs 5.80kg / 12.8lbs and the Sonus Lumina II weighs 5.65kg / 12.4lbs. This makes the Lumina II Amator 3% heavier than the Lumina II.
Here is a comparison of how Lumina II Amator and Lumina II's weights compare with the average, max and min weights in Passive Bookshelf class.

Siblings in Sonus faber's Lumina series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (55Hz vs 55Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (86dB vs 86dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (150W vs 150W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Sonus faber Lumina II Amator: bi-amping; Sonus Lumina II: bi-amping. |
| Price | B | Sonus Lumina II is cheaper - $1,199 against $1,499, about 20% less. |
A Sonus faber Lumina II Amator B Sonus Lumina II
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Match it to your room: we rate Sonus faber Lumina II Amator the better fit for near-field listening and a small room, and Sonus Lumina II for a mid-size room and a large room.
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.
