Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Wharfedale D310 and Wharfedale 220 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

D310 features a 1" Soft-Dome Tweeter and 1 x 4" Woven Kevlar Woofer . On the other hand, the Diamond 220 features a 1" Dome Tweeter and 1 x 5" Woven Kevlar Woofer with a Crossover frequency at 2200Hz.
Frequency Response
D310 has a frequency range of 65-20k Hz whereas Diamond 220 has a frequency range of 56-20k Hz. With a minimum frequency of 56Hz, the Diamond 220 can go significantly deeper on the low side and provide stronger bass compared to the D310's min frequency of 65Hz.
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
D310 and Diamond 220 have the same Impedance of 8 ohms and their sensitivity is also same at 86 dB.

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.
D310 can handle a max power of 100 watts RMS from the amp the whereas D310 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
Diamond 220 features Post posts which make bi-amping or bi-wiring possible. D310 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both D310 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 D310's and Wharfedale 220's external dimensions. Wharfedale D310 has external dimensions of 266.0 x 156.0 x 224.0mm ( 10-7/16 x 6-1/8 x 8-13/16inch) whereas Wharfedale 220 has external dimensions of 315.0 x 174.0 x 255.0mm ( 12.4 x 6.8 x 10.0inch) .
Wharfedale 220 is clearly the larger of the two speakers. Its body is 18mm wider, 49mm taller and 31mm deeper than Wharfedale D310.
Below you can see the front view size comparison of Wharfedale D310 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 D310 is approximately 349.4cm2 / 54.2inch2 and base area of the Wharfedale 220 is approximately 443.7cm2 / 68.8inch2. The D310 requires 21% less surface area than the Diamond 220 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 Wharfedale D310 weighs 4.00kg / 8.8lbs and the Wharfedale 220 weighs 5.32kg / 11.7lbs. This makes the Diamond 220 33% heavier than the D310.
