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 Motion XT C100 features a 1.25 x 2.4" Folded Motion XT Tweeter and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 1300Hz and 2500Hz.
Frequency Response
Motion C10 has a frequency range of 63-25k Hz whereas Motion XT C100 has a frequency range of 42-25k Hz. With a minimum frequency of 42Hz, the Motion XT C100 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.

MartinLogan Motion XT C100
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 Motion XT C100 which has a nominal impedance of 5 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.
On the other hand, they have the same sensitivity of 93 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.
Motion C10 can handle a max power of 300 watts RMS from the amp the whereas Motion C10 has a max power handling value of 200 watts RMS , 100 watts less than the Motion XT C100.
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 XT C100 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.

MartinLogan Motion XT C100's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Motion C10 and Motion XT C100 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 MartinLogan Motion XT C100'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 MartinLogan Motion XT C100 has external dimensions of 203 x 610 x 368mm ( 8inch x 24inch x 14-1/2inch ) .
MartinLogan Motion XT C100 is clearly the larger of the two speakers. Its body is 127mm wider, 19mm taller and 75mm 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 MartinLogan Motion XT C100 is approximately 2244.8cm2 / 347.9inch2. The Motion C10 requires 37% less surface area than the Motion XT C100 which gives it a small advantage on placement in tight spaces.
