607 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer .
Frequency Response
607 S2 AE and 606 S2 AE 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.

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 606 S2 AE 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 606 S2 AE's is at 88 dB. This 4 dB difference makes the B&W 606 S2 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 120 watts RMS from the amp the whereas 607 S2 AE has a max power handling value of 100 watts RMS , 20 watts less than the 606 S2 AE.
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 607 S2 AE and 606 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 607 S2's Binding post terminals allows Bi-amping or bi-wiring
B&W 606 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 607 S2 AE and 606 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 B&W 607 S2's and B&W 606 S2'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 B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm ( 13-5/8 x 7-1/2 x 12-13/16inch) .
B&W 606 S2 is clearly the larger of the two speakers. Its body is 25mm wider, 46mm taller and 94mm deeper than B&W 607 S2.
Below you can see the front view size comparison of B&W 607 S2 and B&W 606 S2 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 S2 is approximately 385.1cm2 / 59.7inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The 607 S2 AE requires 38% less surface area than the 606 S2 AE 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 S2 weighs 4.70kg / 10.3lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the 606 S2 AE 47% heavier than the 607 S2 AE.
Here is a comparison of how 607 S2 AE and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.
