Motion 50XTi features a 1.25 x 2.4" Folded Motion XT Tweeter and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 900Hz and 2200Hz. On the other hand, the Silver C250 7G features a 1" gold dome C-CAM Tweeter , a 3" Midrange and 2 x 5.25" C-CAM with Rigid Surface Technology (RST) Woofer .
Frequency Response
Motion 50XTi has a frequency range of 50-25k Hz whereas Silver C250 7G has a frequency range of 65-35k Hz. With a minimum frequency of 50Hz, the Motion 50XTi can go significantly deeper on the low side and provide stronger bass compared to the Silver C250 7G's min frequency of 65Hz.
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 Center Channel class in our database.

Monitor Audio Silver C250 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 50XTi is a 4 ohms speaker compared to the Silver C250 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 50XTi can provide this impedance level.
These two speakers also have different sensitivity levels. Motion 50XTi sensitivity is rated at 94 dB and the Silver C250 7G's is rated at 88.5 dB. This 5 dB difference makes the MartinLogan 50XTi a more sensitive speaker compared to Monitor Audio Silver C250 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 50XTi can handle a max power of 300 watts RMS from the amp the whereas Silver C250 7G has a max power handling value of 200 watts RMS, 100 watts less than the Motion 50XTi.
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 50XTi features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Silver C250 7G has a Binding post which doesn't feature bi-amping/bi-wiring.
MartinLogan 50XTi's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or 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 50XTi's and Monitor Audio Silver C250 7G's external dimensions. MartinLogan 50XTi has external dimensions of 196.0 x 585.0 x 347.0mm ( 7-11/16 x 23 x 13-5/8inch) whereas Monitor Audio Silver C250 7G has external dimensions of 205.0 x 482.0 x 274.0mm ( 8-1/16 x 18-15/16 x 10-3/4inch) .
Monitor Audio Silver C250 7G is 103mm narrower and 73mm less deeper than MartinLogan 50XTi but it is also 9mm taller.
Below you can see the front view size comparison of MartinLogan 50XTi and Monitor Audio Silver C250 7G in scale.

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 50XTi is approximately 2030.0cm2 / 314.7inch2 and base area of the Monitor Audio Silver C250 7G is approximately 1320.7cm2 / 204.7inch2. The Motion 50XTi requires 54% more surface area than the Silver C250 7G 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 50XTi weighs 13.86kg / 30.5lbs and the Monitor Audio Silver C250 7G weighs 10.63kg / 23.4lbs. This makes the Motion 50XTi 30% heavier than the Silver C250 7G.
Here is a comparison of how Motion 50XTi and Silver C250 7G's weights compare with the average, max and min weights in Passive Center Channel class.
