In this review, we will be comparing 607 S3 and M106, two Passive Bookshelf speakers from Bowers Wilkins and Revel. Let's have a brief look at the main features
of B&W 607 S3 and Revel M106 first before getting into our more
detailed comparison.
What size room are the B&W 607 S3 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 B&W 607 S3 and Revel M106 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

607 S3 features a 1" Titanium Decoupled Double Dome Titanium Tweeter and 1 x 5" Continuum Woofer . 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
607 S3 has a frequency range of 52-28k Hz whereas M106 has a frequency range of 59Hz- 20kHz. With a minimum frequency of 52Hz, the 607 S3 can go significantly deeper on the low side and provide stronger bass compared to the M106's min frequency of 59Hz.
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.

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
607 S3 and M106 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 607 S3 sensitivity is rated at 84 dB and the M106's is at 87 dB. This 3 dB difference makes the Revel M106 a more sensitive speaker compared to B&W 607 S3, 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.
607 S3 can handle a max power of 150 watts RMS from the amp the whereas 607 S3 has a max power handling value of 100 watts RMS , 50 watts less than the M106.
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 S3 features Binding post posts which make bi-amping or bi-wiring possible. M106 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both 607 S3 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 B&W 607 S3's and Revel M106's external dimensions. B&W 607 S3 has external dimensions of 300.0 x 166.0 x 235.0mm ( 11.8 x 6.5 x 9.3inch) 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 44mm wider, 83mm taller and 45mm deeper than B&W 607 S3.
Below you can see the front view size comparison of B&W 607 S3 and Revel M106 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 B&W 607 S3 is approximately 390.1cm2 / 60.5inch2 and base area of the Revel M106 is approximately 588.0cm2 / 91.1inch2. The 607 S3 requires 34% less surface area than the M106 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 B&W 607 S3 weighs 4.65kg / 10.2lbs and the Revel M106 weighs 8.41kg / 18.5lbs. This makes the M106 81% heavier than the 607 S3.
Here is a comparison of how 607 S3 and M106's weights compare with the average, max and min weights in Passive Bookshelf class.
