History
What size room are the Sonus faber Stradivari and Sonus faber Amati 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:

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 Stradivari and Amati are 4-way speakers.

Stradivari features a 1.1" Silk Soft-Dome Tweeter, a 6" Midrange and 2 x 10" Paper Woofer with a Crossover frequency at 160, 220, 2200 Hz. On the other hand, the Amati features a 1.1" Silk Soft-Dome Tweeter, a 6" Midrange and 2 x 8.5" Paper Woofer with a Crossover frequency at 200, 270, 2200 Hz.
Frequency Response
Stradivari has a frequency range of 25-35k Hz whereas Amati has a frequency range of 28-35k Hz. With a minimum frequency of 25Hz, the Stradivari can go slightly deeper then the Amati's min frequency of 28Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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
Stradivari and Amati have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Stradivari sensitivity is rated at 92 dB and the Amati's is at 91 dB. This 1 dB difference makes the Sonus faber Stradivari a more sensitive speaker compared to Sonus faber Amati, 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 Stradivari and the Stradivari can provide this impedance level.
Sensitivity
Floor-standing 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.
Stradivari can handle a max power of 600 watts RMS, whereas Amati has a max power handling value of 450 watts RMS, 150 watts less than the Stradivari.
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 Stradivari and Amati 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 Stradivari's and Sonus faber Amati's external dimensions. Sonus faber Stradivari has external dimensions of 1374.0 x 715.0 x 428.0mm (54-1/8 x 28-1/8 x 16-7/8inch) whereas Sonus faber Amati has external dimensions of 1176.0 x 411.0 x 512.0mm (46-5/16 x 16-3/16 x 20-3/16inch).
Sonus faber Amati is 304mm narrower and 198mm shorter than Sonus faber Stradivari but it is also 84mm deeper.
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.
Sonus faber Stradivari needs about 45% more floor or shelf area. Sonus faber Amati is 84mm deeper, so it stands that much further out from the wall. Sonus faber Stradivari is 198mm 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 Stradivari is approximately 3060.2cm2 / 474.3inch2 and base area of the Sonus faber Amati is approximately 2104.3cm2 / 326.2inch2. The Stradivari requires 45% more surface area than the Amati which gives it a small disadvantage 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 Stradivari weighs 81.50kg / 179.3lbs and the Sonus faber Amati weighs 61.00kg / 134.2lbs. This makes the Stradivari 34% heavier than the Amati.
Here is a comparison of how Stradivari and Amati's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Sonus faber's Homage series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Sonus faber Stradivari digs deeper - 25Hz against 28Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (92dB vs 91dB) - both want much the same power. |
| Headroom | A | Sonus faber Stradivari takes more power (600W vs 450W) - more in hand in a big room. |
| Size | depends | Sonus faber Amati is easier to place; Sonus faber Stradivari is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Sonus faber Stradivari: bi-amping; Sonus faber Amati: bi-amping. |
| Price | B | Sonus faber Amati is cheaper - $29,998 against $50,000, about 40% less; arguably a different class. |
A Sonus faber Stradivari B Sonus faber Amati
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?
The usual trade-off: Sonus faber Stradivari measures better, Sonus faber Amati costs about about 67% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. Match it to your room: we rate Sonus faber Stradivari the better fit for a very large room; elsewhere the two are rated the same. In a large or open-plan room, Sonus faber Stradivari has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Sonus faber Amati is the easier speaker to get right.
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.
