History
What size room are the MartinLogan 35XTi and MartinLogan 50XTi speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the MartinLogan 35XTi and MartinLogan 50XTi compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Motion 35XTi is a 2-way design whereas the Motion 50XTi 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.

Motion 35XTi features a 1.25 x 2.4" Folded Motion XT Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2200Hz. On the other hand, the 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.
Frequency Response
Motion 35XTi and Motion 50XTi has exactly the same frequency range of 50-25k Hz.
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 Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
High Frequency
Bookshelf Speakers
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 35XTi and Motion 50XTi have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Motion 35XTi sensitivity is rated at 92 dB and the Motion 50XTi's is at 94 dB. This 2 dB difference makes the MartinLogan 50XTi a more sensitive speaker compared to MartinLogan 35XTi, 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 35XTi and the Motion 35XTi 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.
Motion 35XTi can handle a max power of 300 watts RMS from the amp the whereas Motion 35XTi has a max power handling value of 250 watts RMS , 50 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
Both Motion 35XTi and Motion 50XTi features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan 35XTi's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
MartinLogan 50XTi's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Motion 35XTi and Motion 50XTi have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 35XTi's and MartinLogan 50XTi's external dimensions. MartinLogan 35XTi has external dimensions of 343.0 x 192.0 x 300.0mm ( 13.5 x 7.5 x 11.8inch) whereas MartinLogan 50XTi has external dimensions of 196.0 x 585.0 x 347.0mm ( 7-11/16 x 23 x 13-5/8inch) .
MartinLogan 35XTi is 393mm narrower and 47mm less deeper than MartinLogan 50XTi but it is also 147mm taller.
Below you can see the front view size comparison of MartinLogan 35XTi and MartinLogan 50XTi 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 35XTi is approximately 576.0cm2 / 89.3inch2 and base area of the MartinLogan 50XTi is approximately 2030.0cm2 / 314.7inch2. The Motion 35XTi requires 72% less surface area than the Motion 50XTi which gives it a small advantage on placement in tight spaces.
