702 S3 features a 1" Tweeter, a 6" Midrange and 3 x 6.5" Aerofoil Woofer. On the other hand, the Aria K2 936K2 features a 1" aluminum/magnesium with waveguide inverted dome Tweeter, a 6.5" Midrange and 3 x 6.5" K2 aramid fiber/fiberglass Woofer.
Frequency Response
702 S3 has a frequency range of 46-28k Hz whereas Aria K2 936K2 has a frequency range of 39-28k Hz. With a minimum frequency of 39Hz, the Aria K2 936K2 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 and Aria K2 936K2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 702 S3 sensitivity is rated at 90 dB and the Aria K2 936K2's is at 92 dB. This 4 dB difference makes the Focal Aria K2 936K2 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.
Both handle the same maximum of 300 watts RMS, though 702 S3 is rated 30-300 watts and Aria K2 936K2 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
702 S3 features Binding post posts which make bi-amping or bi-wiring possible. Aria K2 936K2 has a Binding post which doesn't feature bi-amping/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 B&W 702 S3's and Focal Aria K2 936K2'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 Focal Aria K2 936K2 has external dimensions of 1148.0 x 294.0 x 374.0mm (45-3/16 x 11-9/16 x 14-11/16inch).
B&W 702 S3 is 102mm narrower and 10mm shorter than Focal Aria K2 936K2 but it is also 17mm deeper.
Below you can see the front view size comparison of B&W 702 S3 and Focal Aria K2 936K2 in scale.

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 Focal Aria K2 936K2 is approximately 1099.6cm2 / 170.4inch2. The 702 S3 requires 32% less surface area than the Aria K2 936K2 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 Focal Aria K2 936K2 weighs 29.09kg / 64lbs. This makes the 702 S3 15% heavier than the Aria K2 936K2.
Here is a comparison of how 702 S3 and Aria K2 936K2'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 | B | Focal Aria K2 936K2 digs deeper - 39Hz against 46Hz. A subwoofer would even that out. |
| Amplifier needs | B | Focal Aria K2 936K2 is more sensitive (92dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | B&W 702 S3 is easier to place; Focal Aria K2 936K2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | B&W 702 S3: bi-amping. |
| Price | evenly matched | Much the same money ($6,998 vs $6,598 a pair). |
A B&W 702 S3 B Focal Aria K2 936K2
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 K2 936K2 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, Focal Aria K2 936K2 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.
