In this review, we will be comparing R6 Meta and HTM71 S3, two Passive Center Channel speakers from KEF and Bowers Wilkins. Let's have a brief look at the main features
of KEF R6 Meta and B&W HTM71 S3 first before getting into our more
detailed comparison.
What size room are the KEF R6 Meta and B&W HTM71 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 R6 Meta and B&W HTM71 S3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R6 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 500Hz and 2400Hz. On the other hand, the HTM71 S3 features a 1" Decoupled Carbon Solid Body Soft-Dome Tweeter , a 4" Midrange and 4 x 5" Aerofoil Profile Woofer .
Frequency Response
R6 Meta has a frequency range of 65-28k Hz whereas HTM71 S3 has a frequency range of 50-28k Hz. With a minimum frequency of 50Hz, the HTM71 S3 can go significantly deeper on the low side and provide stronger bass compared to the R6 Meta's min frequency of 65Hz.
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 Center Channel class in our database.

High Frequency
Center Channel 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
R6 Meta is a 4 ohms speaker compared to the HTM71 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 R6 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R6 Meta sensitivity is rated at 88 dB and the HTM71 S3's is rated at 89 dB. This 1 dB difference makes the B&W HTM71 S3 a more sensitive speaker compared to KEF R6 Meta, 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.
R6 Meta can handle a max power of 250 watts RMS from the amp the whereas HTM71 S3 has a max power handling value of 200 watts RMS, 50 watts less than the R6 Meta.
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 R6 Meta and HTM71 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R6 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
B&W HTM71 S3's Binding post terminals allows Bi-amping or 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 KEF R6 Meta's and B&W HTM71 S3's external dimensions. KEF R6 Meta has external dimensions of 202.0 x 626.0 x 339.0mm ( 7-15/16-inch x 24-5/8-inch x 13-5/16-inch) whereas B&W HTM71 S3 has external dimensions of 235.0 x 629.0 x 356.0mm ( 9-1/4inch x 24-3/4inch x 14inch ) .
B&W HTM71 S3 is clearly the larger of the two speakers. Its body is 3mm wider, 33mm taller and 17mm deeper than KEF R6 Meta.
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 R6 Meta is approximately 2122.1cm2 / 328.9inch2 and base area of the B&W HTM71 S3 is approximately 2239.2cm2 / 347.1inch2. The R6 Meta requires 5% less surface area than the HTM71 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 KEF R6 Meta weighs 17.82kg / 39.2lbs and the B&W HTM71 S3 weighs 17.50kg / 38.5lbs. This makes the R6 Meta 2% heavier than the HTM71 S3.
Here is a comparison of how R6 Meta and HTM71 S3's weights compare with the average, max and min weights in Passive Center Channel class.
