In this review, we will be comparing Aria 906 and Motion 15, two Passive Bookshelf speakers from Focal and MartinLogan. Let's have a brief look at the main features
of Focal Aria 906 and MartinLogan 15 first before getting into our more
detailed comparison.
What size room are the Focal Aria 906 and MartinLogan 15 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:

Aria 906 features a 1" TNF aluminum/magnesium Inverted Hard Dome Tweeter and 1 x 6.5" Flax Woofer with a Crossover frequency at 2800Hz. On the other hand, the 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.
Frequency Response
Aria 906 has a frequency range of 55-28k Hz whereas Motion 15 has a frequency range of 60-25k Hz. With a minimum frequency of 55Hz, the Aria 906 can go significantly deeper on the low side and provide stronger bass compared to 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

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
Aria 906 is a 8 ohms speaker compared to the Motion 15 which has a nominal impedance of 5 ohms.
These two speakers also have different sensitivity levels. Aria 906 sensitivity is rated at 89.5 dB and the Motion 15's is rated at 92 dB. This 2 dB difference makes the MartinLogan 15 a more sensitive speaker compared to Focal Aria 906, 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.
Aria 906 can handle a max power of 200 watts RMS from the amp the whereas Aria 906 has a max power handling value of 120 watts RMS , 80 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
Aria 906 features Custom 5-way tool-less binding posts type posts and Motion 15 has a Custom 5-way tool-less binding posts type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Aria 906 and Motion 15 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 Focal Aria 906's and MartinLogan 15's external dimensions. Focal Aria 906 has external dimensions of 391.0 x 228.0 x 288.0mm ( 15-3/8 x 8-15/16 x 11-5/16inch) whereas MartinLogan 15 has external dimensions of 290.0 x 173.0 x 240.0mm ( 11.4 x 6.8 x 9.4inch) .
Focal Aria 906 is clearly the larger of the two speakers. Its body is 55mm wider, 101mm taller and 48mm 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 Focal Aria 906 is approximately 656.6cm2 / 101.8inch2 and base area of the MartinLogan 15 is approximately 415.2cm2 / 64.4inch2. The Aria 906 requires 58% more surface area than the Motion 15 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 Focal Aria 906 weighs 8.64kg / 19lbs and the MartinLogan 15 weighs 5.40kg / 11.9lbs. This makes the Aria 906 60% heavier than the Motion 15.
Here is a comparison of how Aria 906 and Motion 15's weights compare with the average, max and min weights in Passive Bookshelf class.
