None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. 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.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
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
Size of a speaker can sometimes become 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.
