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 Silver 100 7G features a 1" Hard-Dome Tweeter and 1 x 8" C-CAM RST II Woofer.
Frequency Response
Lumina II Amator has a frequency range of 55-24k Hz whereas Silver 100 7G has a frequency range of 35-35k Hz. With a minimum frequency of 35Hz, the Silver 100 7G can go significantly deeper on the low side and provide stronger bass compared to the Lumina II Amator's min frequency of 55Hz.
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 is a 4 ohms speaker compared to the Silver 100 7G which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Lumina II Amator can provide this impedance level.
These two speakers also have different sensitivity levels. Lumina II Amator sensitivity is rated at 86 dB and the Silver 100 7G's is rated at 87.5 dB. This 2 dB difference makes the Monitor Audio Silver 100 7G a more sensitive speaker compared to Sonus faber Lumina II Amator, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf Speakers
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 can handle a max power of 150 watts RMS, whereas Silver 100 7G has a max power handling value of 120 watts RMS, 30 watts less than the Lumina II 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.

Input Type and Bi-Amping / Bi-Wiring
Both Lumina II Amator and Silver 100 7G 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 Monitor Audio Silver 100 7G'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 Monitor Audio Silver 100 7G has external dimensions of 377.0 x 232.0 x 332.0mm (14-13/16 x 9-1/8 x 13-1/16inch).
Monitor Audio Silver 100 7G is clearly the larger of the two speakers. Its body is 52mm wider, 73mm taller and 69mm deeper than Sonus faber Lumina II Amator.
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.
Monitor Audio Silver 100 7G needs about 63% more floor or shelf area. Monitor Audio Silver 100 7G is 69mm deeper, so it stands that much further out from the wall. Monitor Audio Silver 100 7G is 73mm 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 faber Lumina II Amator is approximately 473.4cm2 / 73.4inch2 and base area of the Monitor Audio Silver 100 7G is approximately 770.2cm2 / 119.4inch2. The Lumina II Amator requires 39% less surface area than the Silver 100 7G 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 faber Lumina II Amator weighs 5.80kg / 12.8lbs and the Monitor Audio Silver 100 7G weighs 9.43kg / 20.7lbs. This makes the Silver 100 7G 63% heavier than the Lumina II Amator.
Here is a comparison of how Lumina II Amator and Silver 100 7G's weights compare with the average, max and min weights in Passive Bookshelf class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | Monitor Audio Silver 100 7G digs deeper - 35Hz against 55Hz. |
| Amplifier needs | B | Monitor Audio Silver 100 7G is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Monitor Audio Silver 100 7G is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | Sonus faber Lumina II Amator takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Sonus faber Lumina II Amator is easier to place; Monitor Audio Silver 100 7G is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Sonus faber Lumina II Amator: bi-amping; Monitor Audio Silver 100 7G: bi-amping. |
| Price | evenly matched | Much the same money ($1,499 vs $1,400 a pair). |
A Sonus faber Lumina II Amator B Monitor Audio Silver 100 7G
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?
Monitor Audio Silver 100 7G has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Sonus faber Lumina II Amator the better fit for near-field listening and a small room, and Monitor Audio Silver 100 7G 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.
