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 30i and MartinLogan 60XTi 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 30i is a 2-way design whereas the Motion 60XTi 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 30i features a 1.0 x 1.4" Folded Motion Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 400Hz and 2600Hz. On the other hand, the Motion 60XTi features a 1.25 x 2.4" Folded Motion XT Tweeter , a 6.5" Midrange and 2 x 8" Aluminum Woofer with a Crossover frequency at 400Hz and 2200Hz.
Frequency Response
Motion 30i has a frequency range of 65-25k Hz whereas Motion 60XTi has a frequency range of 35-25k Hz. With a minimum frequency of 35Hz, the Motion 60XTi can go significantly deeper on the low side and provide stronger bass compared to the Motion 30i'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.

Center Channel 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 30i and Motion 60XTi have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Motion 30i sensitivity is rated at 91 dB and the Motion 60XTi's is at 94 dB. This 3 dB difference makes the MartinLogan 60XTi a more sensitive speaker compared to MartinLogan 30i, 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 30i and the Motion 30i 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 30i can handle a max power of 400 watts RMS from the amp the whereas Motion 30i has a max power handling value of 200 watts RMS , 200 watts less than the Motion 60XTi.
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 60XTi features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Motion 30i has a Custom 5-way tool-less binding posts which doesn't feature bi-amping/bi-wiring.

MartinLogan 60XTi's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Motion 30i and Motion 60XTi 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 30i's and MartinLogan 60XTi's external dimensions. MartinLogan 30i has external dimensions of 177.0 x 423.0 x 281.0mm ( 6-15/16 x 16-5/8 x 11-1/16inch) whereas MartinLogan 60XTi has external dimensions of 1174.0 x 231.0 x 396.0mm ( 46-3/16 x 9-1/16 x 15-9/16inch) .
MartinLogan 30i is 997mm shorter and 115mm less deeper than MartinLogan 60XTi but it is also 192mm wider.
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 30i is approximately 1188.6cm2 / 184.2inch2 and base area of the MartinLogan 60XTi is approximately 914.8cm2 / 141.8inch2. The Motion 30i requires 30% more surface area than the Motion 60XTi which gives it a small disadvantage on placement in tight spaces.
