What size room are the B&W 607 S2 and Revel M126Be 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:

607 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the M126Be features a 1" beryllium Hard-Dome Tweeter and 1 x 6.5" DCC Aluminum Woofer .
Frequency Response
607 S2 AE has a frequency range of 52-28k Hz whereas M126Be has a frequency range of 54-44k Hz. With a minimum frequency of 52Hz, the 607 S2 AE can go slightly deeper then the M126Be's min frequency of 54Hz.
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
607 S2 AE and M126Be have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 607 S2 AE sensitivity is rated at 84 dB and the M126Be's is at 86 dB. This 2 dB difference makes the Revel M126Be 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.
607 S2 AE can handle a max power of 150 watts RMS from the amp the whereas 607 S2 AE has a max power handling value of 100 watts RMS , 50 watts less than the M126Be.
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. M126Be has a Binding post 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 607 S2 AE and M126Be 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 S2's and Revel M126Be's external dimensions. 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) whereas Revel M126Be has external dimensions of 388.0 x 212.0 x 262.0mm ( 15-1/4 x 8-5/16 x 10-5/16inch) .
Revel M126Be is clearly the larger of the two speakers. Its body is 46mm wider, 87mm taller and 30mm deeper than B&W 607 S2.
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 S2 is approximately 385.1cm2 / 59.7inch2 and base area of the Revel M126Be is approximately 555.4cm2 / 86.1inch2. The 607 S2 AE requires 31% less surface area than the M126Be which gives it a small advantage on placement in tight spaces.
