Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz. On the other hand, the Reva 2 features a 1" woven textile Dome Tweeter and 1 x 5" Woven Glass Fiber Woofer .
Frequency Response
Diamond 225 has a frequency range of 45-20k Hz whereas Reva 2 has a frequency range of 48-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go slightly deeper then the Reva 2's min frequency of 48Hz.
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
Diamond 225 and Reva 2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 225 sensitivity is rated at 87 dB and the Reva 2's is at 86 dB. This 1 dB difference makes the Wharfedale 225 a more sensitive speaker compared to Wharfedale Reva 2, 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.
Diamond 225 can handle a max power of 120 watts RMS from the amp the whereas Reva 2 has a max power handling value of 80 watts RMS, 40 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 Diamond 225 and Reva 2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Diamond 225 and Reva 2 have bottom firing ports.
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 Wharfedale 225's and Wharfedale Reva 2's external dimensions. Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) whereas Wharfedale Reva 2 has external dimensions of 358.0 x 201.0 x 326.0mm ( 14-1/16 x 7-7/8 x 12-13/16inch) .
Wharfedale Reva 2 is clearly the larger of the two speakers. Its body is 5mm wider, 3mm taller and 36mm deeper than Wharfedale 225.
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 Wharfedale 225 is approximately 568.4cm2 / 88.1inch2 and base area of the Wharfedale Reva 2 is approximately 655.3cm2 / 101.6inch2. The Diamond 225 requires 13% less surface area than the Reva 2 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 Wharfedale 225 weighs 6.55kg / 14.4lbs and the Wharfedale Reva 2 weighs 7.82kg / 17.2lbs. This makes the Reva 2 19% heavier than the Diamond 225.
Here is a comparison of how Diamond 225 and Reva 2's weights compare with the average, max and min weights in Passive Bookshelf class.
