Drivers
One of the fundamental differences between these two speakers is that Motion F10 is a 3-way design whereas the Motion C10 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.

Motion F10 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter , a 5.5" Midrange and 2 x 5.5" Aluminum Woofer with a Crossover frequency at 280Hz and 3000Hz. On the other hand, the 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.
Frequency Response
Motion F10 has a frequency range of 38-25k Hz whereas Motion C10 has a frequency range of 63-25k Hz. With a minimum frequency of 38Hz, the Motion F10 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 Floor-standing class in our database.

High Frequency
Floor-standing 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 F10 and Motion C10 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Motion F10 sensitivity is rated at 92 dB and the Motion C10's is at 93 dB. This 1 dB difference makes the MartinLogan Motion C10 a more sensitive speaker compared to MartinLogan Motion F10, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Motion F10 and the Motion F10 can provide this impedance level.

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.
Motion F10 can handle a max power of 250 watts RMS from the amp the whereas Motion C10 has a max power handling value of 200 watts RMS, 50 watts less than the Motion F10.
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 F10 features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Motion C10 has a Custom 5-way binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Motion F10 has a bottom firing port whereas Motion C10 has a rear firing ports. MartinLogan Motion F10's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to MartinLogan Motion C10 with its rear-firing port.
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 F10's and MartinLogan Motion C10's external dimensions. MartinLogan Motion F10 has external dimensions of 971 x 286 x 336mm ( 38-1/4inch x 11-1/4inch x 13-1/4inch ) whereas MartinLogan Motion C10 has external dimensions of 184 x 483 x 293mm ( 7-1/4inch x 19inch x 11-1/2inch ) .
MartinLogan Motion C10 is 787mm shorter and 43mm less deeper than MartinLogan Motion F10 but it is also 197mm wider.
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 F10 is approximately 961.0cm2 / 149.0inch2 and base area of the MartinLogan Motion C10 is approximately 1415.2cm2 / 219.4inch2. The Motion F10 requires 32% less surface area than the Motion C10 which gives it a small advantage on placement in tight spaces.
