BW 607 and BW 606 are members of Bowers Wilkins's 600 series of speakers. Below you can find the loudspeakers from this series.
What size room are the B&W 607 and B&W 606 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:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the B&W 607 and B&W 606 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

BW 607 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the BW 606 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
BW 607 and BW 606 has exactly the same frequency range of 52-28k Hz.
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
BW 607 and BW 606 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BW 607 sensitivity is rated at 84 dB and the BW 606's is at 88 dB. This 4 dB difference makes the B&W 606 a more sensitive speaker compared to B&W 607, 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.
BW 607 can handle a max power of 120 watts RMS from the amp the whereas BW 607 has a max power handling value of 100 watts RMS , 20 watts less than the BW 606.
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
Both BW 607 and BW 606 features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 606's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both BW 607 and BW 606 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's and B&W 606's external dimensions. B&W 607 has external dimensions of 300.0 x 165.0 x 207.0mm ( 11.8 x 6.4 x 8.1inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .
B&W 606 is clearly the larger of the two speakers. Its body is 25mm wider, 45mm taller and 117mm deeper than B&W 607.
Below you can see the front view size comparison of B&W 607 and B&W 606 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 is approximately 341.6cm2 / 52.9inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The BW 607 requires 45% less surface area than the BW 606 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 weighs 4.70kg / 10.3lbs and the B&W 606 weighs 6.90kg / 15.2lbs. This makes the BW 606 47% heavier than the BW 607.
Here is a comparison of how BW 607 and BW 606's weights compare with the average, max and min weights in Passive Bookshelf class.
