607 S3 features a 1" Titanium Decoupled Double Dome Titanium Tweeter and 1 x 5" Continuum Woofer . On the other hand, the Demand D11 features a 1" Hard-Dome Tweeter and 1 x 6.5" Polypropylene Woofer .
Frequency Response
607 S3 has a frequency range of 52-28k Hz whereas Demand D11 has a frequency range of 61-22k Hz. With a minimum frequency of 52Hz, the 607 S3 can go significantly deeper on the low side and provide stronger bass compared to the Demand D11's min frequency of 61Hz.
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 Demand D11 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 Demand D11's is at 90 dB. This 6 dB difference makes the Definitive Demand D11 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 200 watts RMS from the amp the whereas 607 S3 has a max power handling value of 100 watts RMS , 100 watts less than the Demand D11.
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 S3 and Demand D11 features dual binding post speaker terminals for bi-amping or bi-wiring.

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 Definitive Demand D11'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 Definitive Demand D11 has external dimensions of 332.0 x 186.0 x 329.0mm ( 13-1/16 x 7-5/16 x 12-15/16inch) .
Definitive Demand D11 is clearly the larger of the two speakers. Its body is 20mm wider, 32mm taller and 94mm deeper than B&W 607 S3.
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 Definitive Demand D11 is approximately 611.9cm2 / 94.8inch2. The 607 S3 requires 36% less surface area than the Demand D11 which gives it a small advantage on placement in tight spaces.
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 Definitive Demand D11 weighs 8.64kg / 19lbs. This makes the Demand D11 86% heavier than the 607 S3.
Here is a comparison of how 607 S3 and Demand D11's weights compare with the average, max and min weights in Passive Bookshelf class.
