702 S3 features a 1" Tweeter, a 6" Midrange and 3 x 6.5" Aerofoil Woofer. 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
702 S3 has a frequency range of 46-28k 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 702 S3's min frequency of 46Hz.
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
702 S3 is a 8 ohms speaker compared to the Sonetto VIII which has a nominal impedance of 4 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 Sonetto VIII can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.
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.
Both handle the same maximum of 300 watts RMS, though 702 S3 is rated 30-300 watts and Sonetto VIII 50-300 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 702 S3 and Sonetto VIII features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Sonus Sonetto VIII's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
702 S3 has a rear firing port whereas Sonetto VIII has a bottom firing ports. Sonus Sonetto VIII's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 702 S3 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 B&W 702 S3's and Sonus Sonetto VIII's external dimensions. B&W 702 S3 has external dimensions of 1138.0 x 192.0 x 391.0mm (44.8-inch x 7.6-inch x 15.4-inch) 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 91mm wider, 50mm taller and 36mm deeper than B&W 702 S3.
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 B&W 702 S3 is approximately 750.7cm2 / 116.4inch2 and base area of the Sonus Sonetto VIII is approximately 1208.4cm2 / 187.3inch2. The 702 S3 requires 38% less surface area than the Sonetto VIII 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 B&W 702 S3 weighs 33.46kg / 73.6lbs and the Sonus Sonetto VIII weighs 26.30kg / 57.9lbs. This makes the 702 S3 27% heavier than the Sonetto VIII.
Here is a comparison of how 702 S3 and Sonetto VIII's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: B&W 702 S3 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | Sonus Sonetto VIII digs deeper - 36Hz against 46Hz. |
| Amplifier needs | B | Sonus Sonetto VIII is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | A | B&W 702 S3 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | B&W 702 S3 is easier to place; Sonus Sonetto VIII is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | B&W 702 S3: bi-amping; Sonus Sonetto VIII: bi-amping. Sonus Sonetto VIII sits in a wider range (11 models), so a matched surround system is easier later. |
| Price | B | Sonus Sonetto VIII is cheaper - $5,499 against $6,998, about 21% less. |
A B&W 702 S3 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?
Sonus Sonetto VIII 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 46Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Sonus Sonetto VIII has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, B&W 702 S3 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.
