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 XT F200 is a 4 ohms speaker compared to the Aria K2 936K2 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 XT F200 can provide this impedance level.
On the other hand, they have the same sensitivity of 92 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 XT F200 can handle a max power of 600 watts RMS from the amp the whereas Aria K2 936K2 has a max power handling value of 300 watts RMS, 300 watts less than the Motion XT F200.
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 F200 features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Aria K2 936K2 has a Binding post which doesn't 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. In this section, we are going to compare MartinLogan Motion XT F200's and Focal Aria K2 936K2's external dimensions. MartinLogan Motion XT F200 has external dimensions of 1289 x 349 x 419mm ( 50-3/4inch x 13-3/4inch x 16-1/2inch ) whereas Focal Aria K2 936K2 has external dimensions of 1148.0 x 294.0 x 374.0mm ( 45-3/16 x 11-9/16 x 14-11/16inch) .
MartinLogan Motion XT F200 is clearly the larger of the two speakers. Its body is 55mm wider, 141mm taller and 45mm deeper than Focal Aria K2 936K2.
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 XT F200 is approximately 1462.3cm2 / 226.7inch2 and base area of the Focal Aria K2 936K2 is approximately 1099.6cm2 / 170.4inch2. The Motion XT F200 requires 33% more surface area than the Aria K2 936K2 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 MartinLogan Motion XT F200 weighs 39.00kg / 85.8lbs and the Focal Aria K2 936K2 weighs 29.09kg / 64lbs. This makes the Motion XT F200 34% heavier than the Aria K2 936K2.
Here is a comparison of how Motion XT F200 and Aria K2 936K2's weights compare with the average, max and min weights in Passive Floor-standing class.
