Drivers
One of the fundamental differences between these two speakers is that 3.7i is a -way design whereas the Motion XT F200 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

3.7i features a " Tweeter and x " Woofer. 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
3.7i has a frequency range of 35-40k 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 3.7i's min frequency of 35Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
3.7i and Motion XT F200 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. 3.7i sensitivity is rated at 86 dB and the Motion XT F200's is at 92 dB. This 6 dB difference makes the MartinLogan Motion XT F200 a more sensitive speaker compared to Magnepan 3.7i, 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 3.7i and the 3.7i can provide this impedance level.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Magnepan 3.7i's and MartinLogan Motion XT F200's external dimensions. Magnepan 3.7i has external dimensions of 1803.4 x 609.6 x 41.3mm (71 x 24 x 1.625inch) 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).
MartinLogan Motion XT F200 is 260.6mm narrower and 514.4mm shorter than Magnepan 3.7i but it is also 377.7mm deeper.
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 Magnepan 3.7i is approximately 251.8cm2 / 39.0inch2 and base area of the MartinLogan Motion XT F200 is approximately 1462.3cm2 / 226.7inch2. The 3.7i requires 83% less surface area than the Motion XT F200 which gives it a small advantage on placement in tight spaces.
