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
703 S3 and 702 S3 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.
703 S3 can handle a max power of 300 watts RMS from the amp the whereas 703 S3 has a max power handling value of 200 watts RMS , 100 watts less than the 702 S3.
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 703 S3 and 702 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 703 S3's Binding post terminals allows Bi-amping or bi-wiring
B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 703 S3 and 702 S3 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 703 S3's and B&W 702 S3's external dimensions. B&W 703 S3 has external dimensions of 1117.0 x 192.0 x 353.0mm ( 44-inch x 7.6-inch x 13.9-inch) 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) .
Below you can see the front view size comparison of B&W 703 S3 and B&W 702 S3 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 703 S3 is approximately 677.8cm2 / 105.1inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The 703 S3 requires 10% less surface area than the 702 S3 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 703 S3 weighs 28.81kg / 63.4lbs and the B&W 702 S3 weighs 33.46kg / 73.6lbs. This makes the 702 S3 16% heavier than the 703 S3.
Here is a comparison of how 703 S3 and 702 S3's weights compare with the average, max and min weights in Passive Floor-standing class.
