BW 607 features a 1" Decoupled Carbon Hard-Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
BW 607 has a frequency range of 52-28k Hz whereas Diamond 225 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go significantly deeper on the low side and provide stronger bass compared to the BW 607's min frequency of 52Hz.
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
BW 607 and Diamond 225 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 Diamond 225's is at 87 dB. This 3 dB difference makes the Wharfedale 225 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 Diamond 225.
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 Diamond 225 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale 225's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
BW 607 has a rear firing port whereas Diamond 225 has a bottom firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 607 with its rear-firing port.
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 Wharfedale 225'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 Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) .
Wharfedale 225 is clearly the larger of the two speakers. Its body is 31mm wider, 55mm taller and 83mm deeper than B&W 607.
Below you can see the front view size comparison of B&W 607 and Wharfedale 225 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 Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The BW 607 requires 40% less surface area than the Diamond 225 which gives it a small advantage on placement in tight spaces.
