In this review, we will be comparing R11 Meta and 702 S3, two Passive Floor-standing speakers from KEF and Bowers Wilkins. Let's have a brief look at the main features
of KEF R11 Meta and B&W 702 S3 first before getting into our more
detailed comparison.
What size room are the KEF R11 Meta and B&W 702 S3 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 KEF R11 Meta and B&W 702 S3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R11 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter , a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 330Hz and 2500Hz. On the other hand, the 702 S3 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer .
Frequency Response
R11 Meta has a frequency range of 46-28 Hz whereas 702 S3 has a 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.
Low Frequency
Floor-standing Speakers
High Frequency
Floor-standing Speakers
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
R11 Meta is a 4 ohms speaker compared to the 702 S3 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the R11 Meta can provide this impedance level.
On the other hand, they have the same sensitivity of 90 dBdB.

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
Both R11 Meta and 702 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R11 Meta's Custom 5-way bi-wire tool-less binding posts 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 R11 Meta 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 KEF R11 Meta's and B&W 702 S3's external dimensions. KEF R11 Meta has external dimensions of 1296.0 x 312.0 x 385.0mm ( 51-inch x 12-1/4-inch x 15-1/8-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) .
B&W 702 S3 is 120mm narrower and 158mm shorter than KEF R11 Meta but it is also 6mm deeper.
Below you can see the front view size comparison of KEF R11 Meta 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 KEF R11 Meta is approximately 1201.2cm2 / 186.2inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The R11 Meta requires 60% more surface area than the 702 S3 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 KEF R11 Meta weighs 36.59kg / 80.5lbs and the B&W 702 S3 weighs 33.46kg / 73.6lbs. This makes the R11 Meta 9% heavier than the 702 S3.
Here is a comparison of how R11 Meta and 702 S3's weights compare with the average, max and min weights in Passive Floor-standing class.
