What size room are the Sonus Sonetto II and Sonus Sonetto VIII 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:

Listening Environment*	Sonus Sonetto II	Sonus Sonetto VIII
Near-field	Poor	Bad
Small Room	Average	Poor
Mid-size Room	Good	Average
Large Room	Average	Good
Very Large Room	Poor	Average

(* Approximate Room sizes: Small < 100sq. ft / 9 m², Mid-size: 100-220 sq. ft / 9-20 m², Large 220-400 sq. ft / 20-36 m², Very Large: > 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

One of the fundamental differences between these two speakers is that Sonetto II is a 2-way design whereas the Sonetto VIII 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.

Driver Setup	2-way	3-way
Tweeter	1.15-inch	1.15-inch
Midrange	-	1 x 6-inch
Woofer	1 x 6.5-inch	3 x 7-inch

Sonetto II features a 1.15" high definition DAD Dome Tweeter and 1 x 6.5" cellulose pulp and other natural fibers Woofer with a Crossover frequency at 2650 Hz. On the other hand, the Sonetto VIII features a 1.15" high definition DAD Dome Tweeter, a 6" Midrange and 3 x 7" aluminum cone Woofer with a Crossover frequency at 270 and 3.000 Hz.

Frequency Response

Sonetto II has a frequency range of 42-25k Hz whereas Sonetto VIII has a frequency range of 36-25k Hz. With a minimum frequency of 36Hz, the Sonetto VIII can go significantly deeper on the low side and provide stronger bass compared to the Sonetto II's min frequency of 42Hz.

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.

Median

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

Sonetto II and Sonetto VIII have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto II sensitivity is rated at 87 dB and the Sonetto VIII's is at 90 dB. This 3 dB difference makes the Sonus Sonetto VIII a more sensitive speaker compared to Sonus Sonetto 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 Sonetto II and the Sonetto II 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.

Sonetto VIII can handle a max power of 300 watts RMS, whereas Sonetto II has a max power handling value of 200 watts RMS, 100 watts less than the Sonetto VIII.

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.

Input Type and Bi-Amping / Bi-Wiring

Both Sonetto II and Sonetto VIII features dual binding post speaker terminals for bi-amping or bi-wiring.

Sonus Sonetto VIII's Binding post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Sonetto II has a front firing port whereas Sonetto VIII has a bottom firing ports. Sonus Sonetto II's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Sonus Sonetto VIII with its rear-firing port.

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 Sonetto II's and Sonus Sonetto VIII's external dimensions. Sonus Sonetto II has external dimensions of 370.0 x 250.0 x 334.0mm (15 x 10 x 13inch) whereas Sonus Sonetto VIII has external dimensions of 1188.0 x 283.0 x 427.0mm (47 x 11 x 17inch).

Sonus Sonetto VIII is clearly the larger of the two speakers. Its body is 33mm wider, 818mm taller and 93mm deeper than Sonus Sonetto II.

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 Sonetto II is approximately 835.0cm² / 129.4inch² and base area of the Sonus Sonetto VIII is approximately 1208.4cm² / 187.3inch². The Sonetto II requires 31% less surface area than the Sonetto VIII which gives it a small advantage on placement in tight spaces.

Verdict

Siblings in Sonus faber's Sonetto series, so they share a family sound. It comes down to size, output and price.

Area	Better	Why
Bass	B	Sonus Sonetto VIII digs deeper - 36Hz against 42Hz. A subwoofer would even that out.
Amplifier needs	B	Sonus Sonetto VIII is more sensitive (90dB vs 87dB), so it goes louder on the same amplifier.
Headroom	B	Sonus Sonetto VIII takes more power (300W vs 200W) - more in hand in a big room.
Size	depends	Sonus Sonetto II is easier to place; Sonus Sonetto VIII is bigger, which usually goes with fuller bass. Your room decides.
Type	depends	A Passive Bookshelf against a Passive Floor-standing - a different job rather than a better one.
Expandability	depends	Sonus Sonetto II: bi-amping; Sonus Sonetto VIII: bi-amping.
Price	A	Sonus Sonetto II is cheaper - $1,499 against $5,499, about 73% less; arguably a different class.

A Sonus Sonetto II B Sonus Sonetto VIII
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 Sonetto VIII measures better, Sonus Sonetto II costs about about 3.7x the price% 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. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 42Hz anyway, which makes the cheaper Sonus Sonetto II much easier to justify. Match it to your room: we rate Sonus Sonetto II the better fit for a small room and a mid-size room, and Sonus Sonetto VIII for a large room and a very 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.
