In this review, we will be comparing two different type of speakers by Bowers Wilkins. Bowers & Wilkins 702 S2 is a Floor-standing speaker whereas the 706 S2 is a Bookshelf speaker.
Let's have a brief look at the main features
of B&W 702 S2 and B&W 706 S2 first before getting into our more
detailed comparison.
702 S2 and 706 S2 are members of Bowers Wilkins's 700 S2 Anniversary Edition series of speakers. Below you can find the loudspeakers from this series.
What size room are the B&W 702 S2 and B&W 706 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 S2 and B&W 706 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that 702 S2 is a 3-way design whereas the 706 S2 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

702 S2 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer . On the other hand, the 706 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
702 S2 has a frequency range of 46-28k Hz whereas 706 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 46Hz, the 702 S2 can go slightly deeper then the 706 S2's min frequency of 50Hz.
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 S2 and 706 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 702 S2 sensitivity is rated at 90 dB and the 706 S2's is at 88 dB. This 2 dB difference makes the B&W 702 S2 a more sensitive speaker compared to B&W 706 S2, 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.
702 S2 can handle a max power of 300 watts RMS from the amp the whereas 706 S2 has a max power handling value of 120 watts RMS, 180 watts less than the 702 S2.
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 S2 and 706 S2 features dual binding post speaker terminals for 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 S2 and 706 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 S2's and B&W 706 S2's external dimensions. 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) whereas B&W 706 S2 has external dimensions of 340.0 x 200.0 x 301.0mm ( 13.5-inch x 7.8-inch x 11.-inch) .
Below you can see the front view size comparison of B&W 702 S2 and B&W 706 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 S2 is approximately 728.0cm2 / 112.8inch2 and base area of the B&W 706 S2 is approximately 602.0cm2 / 93.3inch2. The 702 S2 requires 21% more surface area than the 706 S2 which gives it a small disadvantage on placement in tight spaces.
