Aria Evo X No4 features a 1" Al/Mg inverted dome Tweeter, a 6.5" Midrange and 2 x 6.5" Flax Woofer with a Crossover frequency at 280 Hz - 2600 Hz. On the other hand, the 702 S3 features a 1" Tweeter, a 6" Midrange and 3 x 6.5" Aerofoil Woofer.
Frequency Response
Aria Evo X No4 has a frequency range of 37-30kHz whereas 702 S3 has a frequency range of 46-28k Hz. With a minimum frequency of 37Hz, the Aria Evo X No4 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
Aria Evo X No4 and 702 S3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X No4 sensitivity is rated at 92.5 dB and the 702 S3's is at 90 dB. This 5 dB difference makes the Focal Aria Evo X No4 a more sensitive speaker compared to B&W 702 S3, hence will play louder with the same amount of watts.
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.
Aria Evo X No4 can handle a max power of 350 watts RMS, whereas 702 S3 has a max power handling value of 300 watts RMS, 50 watts less than the Aria Evo X No4.
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
702 S3 features Binding post posts which make bi-amping or bi-wiring possible. Aria Evo X No4 has a Binding post which doesn't feature bi-amping/bi-wiring.

B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Aria Evo X No4 has a front firing port whereas 702 S3 has a rear firing ports. Focal Aria Evo X No4's front-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 Focal Aria Evo X No4's and B&W 702 S3's external dimensions. Focal Aria Evo X No4 has external dimensions of 115 x 37.1 x 42 cm (45-¼ x 14-⅝ x 16-½) whereas 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).
Focal Aria Evo X No4 is clearly the larger of the two speakers. Its body is 179mm wider, 12mm taller and 29mm 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 Focal Aria Evo X No4 is approximately 1558.2cm2 / 241.5inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The Aria Evo X No4 requires 108% more surface area than the 702 S3 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 Focal Aria Evo X No4 weighs 35.00kg / 77lbs and the B&W 702 S3 weighs 33.46kg / 73.6lbs. This makes the Aria Evo X No4 5% heavier than the 702 S3.
Here is a comparison of how Aria Evo X No4 and 702 S3's weights compare with the average, max and min weights in Passive Floor-standing 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 | A | Focal Aria Evo X No4 digs deeper - 37Hz against 46Hz. A subwoofer would even that out. |
| Amplifier needs | A | Focal Aria Evo X No4 is more sensitive (93dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (350W vs 300W). |
| Size | depends | B&W 702 S3 is easier to place; Focal Aria Evo X No4 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | B&W 702 S3: bi-amping. B&W 702 S3 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | Focal Aria Evo X No4 is cheaper - $5,998 against $6,998, about 14% less. |
A Focal Aria Evo X No4 B B&W 702 S3
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?
Focal Aria Evo X No4 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. Match it to your room: we rate Focal Aria Evo X No4 the better fit for a very large room; elsewhere the two are rated the same.
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.
