Axis features a 1.25x2.4" Folded Motion Ribbon Tweeter and 2 x 5.25" Aluminum Woofer . On the other hand, the Motion XT CI XTW5-LCR features a 1.27 x 2.4" Folded Motion Ribbon Tweeter and 2 x 5.25" Kevlar Woofer .
Frequency Response
Axis has a frequency range of 45-25kHz whereas Motion XT CI XTW5-LCR has a frequency range of 61-25kHz. With a minimum frequency of 45Hz, the Axis can go significantly deeper on the low side and provide stronger bass compared to the Motion XT CI XTW5-LCR's min frequency of 61Hz.
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 In-wall class in our database.

MartinLogan Motion XT CI XTW5-LCR
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
Axis is a 4 ohms speaker compared to the Motion XT CI XTW5-LCR 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 Axis can provide this impedance level.
These two speakers also have different sensitivity levels. Axis sensitivity is rated at 94 dB and the Motion XT CI XTW5-LCR's is rated at 92 dB. This 2 dB difference makes the MartinLogan Axis a more sensitive speaker compared to MartinLogan Motion XT CI XTW5-LCR, 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.
Axis can handle a max power of 250 watts RMS from the amp the whereas Motion XT CI XTW5-LCR has a max power handling value of 125 watts RMS, 125 watts less than the Axis.
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
Axis features Spring post type posts and Motion XT CI XTW5-LCR has a Spring post type posts. None of these speakers feature bi-amping/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.
