In this review, we will be comparing Motion 15 and M106, two Passive Bookshelf speakers from MartinLogan and Revel. Let's have a brief look at the main features
of MartinLogan 15 and Revel M106 first before getting into our more
detailed comparison.
What size room are the MartinLogan 15 and Revel M106 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:
In the following sections, we will get into more detail in order to better understand how the MartinLogan 15 and Revel M106 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Motion 15 features a 1.0 x 1.4" Folded Motion Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2700Hz. On the other hand, the M106 features a 1" aluminum Hard-Dome with Acoustic Lens Waveguide Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Motion 15 has a frequency range of 60-25k Hz whereas M106 has a frequency range of 59Hz- 20kHz. With a minimum frequency of 59Hz, the M106 can go slightly deeper then the Motion 15's min frequency of 60Hz.
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.

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 15 is a 5 ohms speaker compared to the M106 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Motion 15 sensitivity is rated at 92 dB and the M106's is rated at 87 dB. This 5 dB difference makes the MartinLogan 15 a more sensitive speaker compared to Revel M106, 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 15 can handle a max power of 200 watts RMS from the amp the whereas M106 has a max power handling value of 150 watts RMS, 50 watts less than the Motion 15.
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 15 features Binding post type posts and M106 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Motion 15 and M106 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 15's and Revel M106's external dimensions. MartinLogan 15 has external dimensions of 290.0 x 173.0 x 240.0mm ( 11.4 x 6.8 x 9.4inch) whereas Revel M106 has external dimensions of 383.0 x 210.0 x 280.0mm ( 15-1/16 x 8-1/4 x 11inch) .
Revel M106 is clearly the larger of the two speakers. Its body is 37mm wider, 93mm taller and 40mm deeper than MartinLogan 15.
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 15 is approximately 415.2cm2 / 64.4inch2 and base area of the Revel M106 is approximately 588.0cm2 / 91.1inch2. The Motion 15 requires 29% less surface area than the M106 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 15 weighs 5.40kg / 11.9lbs and the Revel M106 weighs 8.41kg / 18.5lbs. This makes the M106 56% heavier than the Motion 15.
Here is a comparison of how Motion 15 and M106's weights compare with the average, max and min weights in Passive Bookshelf class.
