Motion XT F200 features a 1.25 x 2.4" Folded Motion XT Tweeter , a 6.5" Midrange and 3 x 8" Aluminum Woofer with a Crossover frequency at 300Hz and 2600Hz. On the other hand, the L800 features a 1" Pinnacle Ring Radiator Tweeter , a 5.25" Midrange and 2 x 10" Polypropylene Woofer with a Crossover frequency at 370Hz and 2800Hz.
Frequency Response
Motion XT F200 has a frequency range of 27-25k Hz whereas L800 has a frequency range of 32-38k Hz. With a minimum frequency of 27Hz, the Motion XT F200 can go significantly deeper on the low side and provide stronger bass compared to the L800's min frequency of 32Hz.
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.

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 and L800 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Motion XT F200 sensitivity is rated at 92 dB and the L800's is at 87 dB. This 5 dB difference makes the MartinLogan Motion XT F200 a more sensitive speaker compared to Polk L800, 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 XT F200 and the Motion XT F200 can provide this impedance level.

Floor-standing Speakers
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 L800 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
Both Motion XT F200 and L800 features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan Motion XT F200's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Polk L800's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Motion XT F200 has a bottom firing port whereas L800 has a down firing ports.
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 Polk L800'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 Polk L800 has external dimensions of 1236.0 x 458.0 x 443.0mm ( 48-5/8 x 18 x 17-7/16inch) .
MartinLogan Motion XT F200 is 109mm narrower and 24mm less deeper than Polk L800 but it is also 53mm taller.
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 Polk L800 is approximately 2028.9cm2 / 314.5inch2. The Motion XT F200 requires 28% less surface area than the L800 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 XT F200 weighs 39.00kg / 85.8lbs and the Polk L800 weighs 68.50kg / 150.7lbs. This makes the L800 76% heavier than the Motion XT F200.
Here is a comparison of how Motion XT F200 and L800's weights compare with the average, max and min weights in Passive Floor-standing class.
