R11 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter , a 5" Midrange and 4 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 330Hz and 2500Hz. On the other hand, the 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.
Frequency Response
R11 Meta has a frequency range of 46-28 Hz whereas Motion XT F200 has a frequency range of 27-25k 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 R11 Meta's min frequency of 46Hz.
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
R11 Meta and Motion XT F200 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. R11 Meta sensitivity is rated at 90 dB and the Motion XT F200's is at 92 dB. This 2 dB difference makes the MartinLogan Motion XT F200 a more sensitive speaker compared to KEF R11 Meta, 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 R11 Meta and the R11 Meta 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.
R11 Meta can handle a max power of 600 watts RMS from the amp the whereas R11 Meta 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 R11 Meta and Motion XT F200 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R11 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows 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
Cabinet Type and Port Position
R11 Meta has a rear firing port whereas Motion XT F200 has a bottom firing ports. MartinLogan Motion XT F200's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF R11 Meta 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 KEF R11 Meta's and MartinLogan Motion XT F200's external dimensions. KEF R11 Meta has external dimensions of 1296.0 x 312.0 x 385.0mm ( 51-inch x 12-1/4-inch x 15-1/8-inch) whereas MartinLogan Motion XT F200 has external dimensions of 1289 x 349 x 419mm ( 50-3/4inch x 13-3/4inch x 16-1/2inch ) .
KEF R11 Meta is 37mm narrower and 34mm less deeper than MartinLogan Motion XT F200 but it is also 7mm 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 KEF R11 Meta is approximately 1201.2cm2 / 186.2inch2 and base area of the MartinLogan Motion XT F200 is approximately 1462.3cm2 / 226.7inch2. The R11 Meta requires 18% less surface area than the Motion XT F200 which gives it a small advantage on placement in tight spaces.
