In this review, we will be comparing R2 Meta and R2c, two Passive Center Channel speakers by KEF Let's have a brief look at the main features
of KEF R2 Meta and KEF R2c first before getting into our more
detailed comparison.
What size room are the KEF R2 Meta and KEF R2c 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 R2 Meta and KEF R2c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R2 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 560Hz and 2500Hz. On the other hand, the R2c features a 1" aluminum Dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
R2 Meta has a frequency range of 67-28k Hz whereas R2c has a frequency range of 74-28k Hz. With a minimum frequency of 67Hz, the R2 Meta can go significantly deeper on the low side and provide stronger bass compared to the R2c's min frequency of 74Hz.
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.
Low Frequency

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
R2 Meta is a 4 ohms speaker compared to the R2c 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 R2 Meta can provide this impedance level.
On the other hand, they have the same sensitivity of 87 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.
R2 Meta and R2c has the same power range of 15-200 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 R2 Meta and R2c features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R2 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
KEF R2c'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 R2 Meta's and KEF R2c's external dimensions. KEF R2 Meta has external dimensions of 177.0 x 553.0 x 312.0mm ( 6-15/16-inch x 21-3/4-inch x 12-1/4-inch) whereas KEF R2c has external dimensions of 177.0 x 551.0 x 316.0mm ( 6-15/16 x 21-11/16 x 12-7/16inch) .
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 R2 Meta is approximately 1725.4cm2 / 267.4inch2 and base area of the KEF R2c is approximately 1741.2cm2 / 269.9inch2. The R2 Meta requires 1% less surface area than the R2c 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 R2 Meta weighs 15.45kg / 34lbs and the KEF R2c weighs 16.90kg / 37.2lbs. This makes the R2c 9% heavier than the R2 Meta.
Here is a comparison of how R2 Meta and R2c's weights compare with the average, max and min weights in Passive Center Channel class.
