In this review, we will be comparing 702 S3 and 702 S2, two Passive Floor-standing speakers by Bowers Wilkins Let's have a brief look at the main features
of B&W 702 S3 and B&W 702 S2 first before getting into our more
detailed comparison.
What size room are the B&W 702 S3 and B&W 702 S2 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:
In the following sections, we will get into more detail in order to better understand how the B&W 702 S3 and B&W 702 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Frequency Response
702 S3 and 702 S2 has exactly the same frequency range of 46-28k Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

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 702 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 88 dB.

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.
702 S3 and 702 S2 has the same power range of 30-300 watts.
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
Both 702 S3 and 702 S2 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
B&W 702 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 702 S3 and 702 S2 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 B&W 702 S2'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 B&W 702 S2 has external dimensions of 1087.0 x 200.0 x 364.0mm ( 42.8-inch x 14-7/16-inch x 14.3-inch) .
B&W 702 S2 is 51mm shorter and 27mm less deeper than B&W 702 S3 but it is also 8mm wider.
Below you can see the front view size comparison of B&W 702 S3 and B&W 702 S2 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 B&W 702 S2 is approximately 728.0cm2 / 112.8inch2. The 702 S3 requires 3% more surface area than the 702 S2 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 B&W 702 S3 weighs 33.46kg / 73.6lbs and the B&W 702 S2 weighs 29.50kg / 64.9lbs. This makes the 702 S3 13% heavier than the 702 S2.
Here is a comparison of how 702 S3 and 702 S2's weights compare with the average, max and min weights in Passive Floor-standing class.
