Drivers
One of the fundamental differences between these two speakers is that Reference 4 Meta is a 3-way design whereas the Kanta Center 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.

Reference 4 Meta features a 1" aluminium dome with MAT Tweeter , a 5" Midrange and 4 x 6.5" aluminium cone Woofer with a Crossover frequency at 450Hz and 2100Hz. On the other hand, the Kanta Center features a 1.1" IAL3 Beryllium Hard-Dome Tweeter and 2 x 6.5" flax cone with TMD (Tuned Mass Damping) suspension Woofer with a Crossover frequency at 2400 Hz.
Frequency Response
Reference 4 Meta has a frequency range of 48-35k Hz whereas Kanta Center has a frequency range of 55-44k Hz. With a minimum frequency of 48Hz, the Reference 4 Meta can go significantly deeper on the low side and provide stronger bass compared to the Kanta Center's min frequency of 55Hz.
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
Reference 4 Meta is a 4 ohms speaker compared to the Kanta Center 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 4 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Reference 4 Meta sensitivity is rated at 88 dB and the Kanta Center's is rated at 92 dB. This 4 dB difference makes the Focal Kanta Center a more sensitive speaker compared to KEF Reference 4 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 4 Meta can handle a max power of 400 watts RMS from the amp the whereas Kanta Center has a max power handling value of 200 watts RMS, 200 watts less than the Reference 4 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
Reference 4 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Kanta Center has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Reference 4 Meta and Kanta Center 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 Reference 4 Meta's and Focal Kanta Center's external dimensions. KEF Reference 4 Meta has external dimensions of 205 x 1090 x 463 mm ( 8.1 x 42.9 x 18.2 in.) whereas Focal Kanta Center has external dimensions of 247.0 x 562.0 x 394.0mm ( 9-11/16inch x 22-1/8inch x 15-1/2inch ) .
Focal Kanta Center is 528mm narrower and 69mm less deeper than KEF Reference 4 Meta but it is also 42mm taller.
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 4 Meta is approximately 5046.7cm2 / 782.2inch2 and base area of the Focal Kanta Center is approximately 2214.3cm2 / 343.2inch2. The Reference 4 Meta requires 128% more surface area than the Kanta Center 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 Reference 4 Meta weighs 45.20kg / 99.4lbs and the Focal Kanta Center weighs 18.00kg / 39.6lbs. This makes the Reference 4 Meta 151% heavier than the Kanta Center.
Here is a comparison of how Reference 4 Meta and Kanta Center's weights compare with the average, max and min weights in Passive Center Channel class.
