In this review, we will be comparing Motion C10 and Kanta Center, two Passive Center Channel speakers from MartinLogan and Focal. Let's have a brief look at the main features
of MartinLogan Motion C10 and Focal Kanta Center first before getting into our more
detailed comparison.
What size room are the MartinLogan Motion C10 and Focal Kanta Center 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 MartinLogan Motion C10 and Focal Kanta Center compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Motion C10 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter and 2 x 5.5" Woven Fiberglass Woofer with a Crossover frequency at 1000Hz and 2000Hz. 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
Motion C10 has a frequency range of 63-25k Hz whereas Kanta Center has a frequency range of 55-44k Hz. With a minimum frequency of 55Hz, the Kanta Center can go significantly deeper on the low side and provide stronger bass compared to the Motion C10's min frequency of 63Hz.
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
Center Channel Speakers
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
Motion C10 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 Motion C10 can provide this impedance level.
These two speakers also have different sensitivity levels. Motion C10 sensitivity is rated at 93 dB and the Kanta Center's is rated at 92 dB. This 1 dB difference makes the MartinLogan Motion C10 a more sensitive speaker compared to Focal Kanta Center, 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.
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
Motion C10 features Binding post type posts and Kanta Center has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Motion C10 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 MartinLogan Motion C10's and Focal Kanta Center's external dimensions. MartinLogan Motion C10 has external dimensions of 184 x 483 x 293mm ( 7-1/4inch x 19inch x 11-1/2inch ) 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 clearly the larger of the two speakers. Its body is 79mm wider, 63mm taller and 101mm deeper than MartinLogan Motion C10.
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 MartinLogan Motion C10 is approximately 1415.2cm2 / 219.4inch2 and base area of the Focal Kanta Center is approximately 2214.3cm2 / 343.2inch2. The Motion C10 requires 36% less surface area than the Kanta Center 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 MartinLogan Motion C10 weighs 10.70kg / 23.5lbs and the Focal Kanta Center weighs 18.00kg / 39.6lbs. This makes the Kanta Center 68% heavier than the Motion C10.
Here is a comparison of how Motion C10 and Kanta Center's weights compare with the average, max and min weights in Passive Center Channel class.
