Motion MP10 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter and 1 x 5.5" Woven Fiberglass Woofer with a Crossover frequency at 2100Hz. On the other hand, the 607 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 5" Continuum Woofer .
Frequency Response
Motion MP10 has a frequency range of 81-25k Hz whereas 607 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 607 S2 AE can go significantly deeper on the low side and provide stronger bass compared to the Motion MP10's min frequency of 81Hz.
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 MP10 is a 5 ohms speaker compared to the 607 S2 AE which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Motion MP10 sensitivity is rated at 92 dB and the 607 S2 AE's is rated at 84 dB. This 8 dB difference makes the MartinLogan Motion MP10 a more sensitive speaker compared to B&W 607 S2, 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 MP10 can handle a max power of 200 watts RMS from the amp the whereas 607 S2 AE has a max power handling value of 100 watts RMS, 100 watts less than the Motion MP10.
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
607 S2 AE features Binding post posts which make bi-amping or bi-wiring possible. Motion MP10 has a Custom 5-way binding posts which doesn't feature bi-amping/bi-wiring.

B&W 607 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Motion MP10 and 607 S2 AE 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 Motion MP10's and B&W 607 S2's external dimensions. MartinLogan Motion MP10 has external dimensions of 356 x 203 x 127mm ( 14inch x 8inch x 5inch ) whereas B&W 607 S2 has external dimensions of 301.0 x 166.0 x 232.0mm ( 11-13/16 x 6-1/2 x 9-1/8inch) .
B&W 607 S2 is 37mm narrower and 55mm shorter than MartinLogan Motion MP10 but it is also 105mm 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 MartinLogan Motion MP10 is approximately 257.8cm2 / 40.0inch2 and base area of the B&W 607 S2 is approximately 385.1cm2 / 59.7inch2. The Motion MP10 requires 33% less surface area than the 607 S2 AE which gives it a small advantage on placement in tight spaces.
