Motion F20 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter , a 5.5" Midrange and 2 x 5.5" Aluminum Woofer with a Crossover frequency at 230Hz and 2600Hz. On the other hand, the Silver 500 7G features a 1" gold dome C-CAM with Uniform Dispersion (UD) Waveguide II Tweeter , a 3" Midrange and 2 x 8" C-CAM RST II Woofer .
Frequency Response
Motion F20 has a frequency range of 35-25k Hz whereas Silver 500 7G has a frequency range of 27-35k Hz. With a minimum frequency of 27Hz, the Silver 500 7G can go significantly deeper on the low side and provide stronger bass compared to the Motion F20's min frequency of 35Hz.
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.

Monitor Audio Silver 500 7G
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 F20 is a 4 ohms speaker compared to the Silver 500 7G 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 F20 can provide this impedance level.
These two speakers also have different sensitivity levels. Motion F20 sensitivity is rated at 92 dB and the Silver 500 7G's is rated at 90.5 dB. This 1 dB difference makes the MartinLogan Motion F20 a more sensitive speaker compared to Monitor Audio Silver 500 7G, 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.
Motion F20 can handle a max power of 300 watts RMS from the amp the whereas Silver 500 7G has a max power handling value of 250 watts RMS, 50 watts less than the Motion F20.
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 F20 and Silver 500 7G features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan Motion F20's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Motion F20 has a bottom firing port whereas Silver 500 7G has a rear firing ports. MartinLogan Motion F20's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Monitor Audio Silver 500 7G 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 MartinLogan Motion F20's and Monitor Audio Silver 500 7G's external dimensions. MartinLogan Motion F20 has external dimensions of 1127 x 298 x 362mm ( 44-3/4inch x 11-3/4inch x 14-1/4inch ) whereas Monitor Audio Silver 500 7G has external dimensions of 1085.0 x 323.0 x 393.0mm ( 42-11/16 x 12-11/16 x 15-7/16inch) .
MartinLogan Motion F20 is 25mm narrower and 31mm less deeper than Monitor Audio Silver 500 7G but it is also 42mm 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 F20 is approximately 1078.8cm2 / 167.2inch2 and base area of the Monitor Audio Silver 500 7G is approximately 1269.4cm2 / 196.8inch2. The Motion F20 requires 15% less surface area than the Silver 500 7G 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 F20 weighs 27.20kg / 59.8lbs and the Monitor Audio Silver 500 7G weighs 22.53kg / 49.6lbs. This makes the Motion F20 21% heavier than the Silver 500 7G.
Here is a comparison of how Motion F20 and Silver 500 7G's weights compare with the average, max and min weights in Passive Floor-standing class.
