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
Reva 1 and Diamond 220 have the same Impedance of 8 ohms and their sensitivity is also same at 86 dB.
Sensitivity

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.
Reva 1 can handle a max power of 100 watts RMS from the amp the whereas Reva 1 has a max power handling value of 60 watts RMS , 40 watts less than the Diamond 220.
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 Reva 1 and Diamond 220 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Both Reva 1 and Diamond 220 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 Reva 1's and Wharfedale 220's external dimensions. Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm ( 12-1/2 x 6-13/16 x 11-3/16inch) whereas Wharfedale 220 has external dimensions of 315.0 x 174.0 x 255.0mm ( 12.4 x 6.8 x 10.0inch) .
Below you can see the front view size comparison of Wharfedale Reva 1 and Wharfedale 220 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 Wharfedale Reva 1 is approximately 495.9cm2 / 76.9inch2 and base area of the Wharfedale 220 is approximately 443.7cm2 / 68.8inch2. The Reva 1 requires 12% more surface area than the Diamond 220 which gives it a small disadvantage 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 Wharfedale Reva 1 weighs 5.64kg / 12.4lbs and the Wharfedale 220 weighs 5.32kg / 11.7lbs. This makes the Reva 1 6% heavier than the Diamond 220.
Here is a comparison of how Reva 1 and Diamond 220's weights compare with the average, max and min weights in Passive Bookshelf class.
