Reference 2 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 2 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. 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
Reference 2 Meta has a frequency range of 80-35k Hz whereas R2c has a frequency range of 74-28k Hz. With a minimum frequency of 74Hz, the R2c can go significantly deeper on the low side and provide stronger bass compared to the Reference 2 Meta's min frequency of 80Hz.
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
Reference 2 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 Reference 2 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Reference 2 Meta sensitivity is rated at 86 dB and the R2c's is rated at 87 dB. This 1 dB difference makes the KEF R2c a more sensitive speaker compared to KEF Reference 2 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.
Reference 2 Meta can handle a max power of 300 watts RMS from the amp the whereas R2c has a max power handling value of 200 watts RMS, 100 watts less than the Reference 2 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 Reference 2 Meta and R2c features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF Reference 2 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 Reference 2 Meta's and KEF R2c's external dimensions. KEF Reference 2 Meta has external dimensions of 205 x 630 x 335 mm ( 8.1 x 24.8 x 13.2 in) 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) .
KEF Reference 2 Meta is clearly the larger of the two speakers. Its body is 79mm wider, 28mm taller and 19mm deeper than KEF R2c.
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 Reference 2 Meta is approximately 2110.5cm2 / 327.1inch2 and base area of the KEF R2c is approximately 1741.2cm2 / 269.9inch2. The Reference 2 Meta requires 21% more surface area than the R2c which gives it a small disadvantage on placement in tight spaces.
