D320 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer . On the other hand, the Diamond 11.2 features a 1" Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer .
Frequency Response
D320 has a frequency range of 56-20k Hz whereas Diamond 11.2 has a frequency range of 48-20k Hz. With a minimum frequency of 48Hz, the Diamond 11.2 can go significantly deeper on the low side and provide stronger bass compared to the D320's min frequency of 56Hz.
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
D320 and Diamond 11.2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D320 sensitivity is rated at 87 dB and the Diamond 11.2's is at 88 dB. This 1 dB difference makes the Wharfedale 11.2 a more sensitive speaker compared to Wharfedale D320, 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.
D320 can handle a max power of 125 watts RMS from the amp the whereas D320 has a max power handling value of 100 watts RMS , 25 watts less than the Diamond 11.2.
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
D320 features Post type posts and Diamond 11.2 has a Post type posts. None of these speakers feature bi-amping/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 Wharfedale D320's and Wharfedale 11.2's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm ( 12-5/8 x 7-1/8 x 10-7/8inch) whereas Wharfedale 11.2 has external dimensions of 356.0 x 223.0 x 321.0mm ( 14 x 8-3/4 x 12-5/8inch) .
Wharfedale 11.2 is clearly the larger of the two speakers. Its body is 42mm wider, 35mm taller and 44mm deeper than Wharfedale D320.
Below you can see the front view size comparison of Wharfedale D320 and Wharfedale 11.2 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 D320 is approximately 501.4cm2 / 77.7inch2 and base area of the Wharfedale 11.2 is approximately 715.8cm2 / 110.9inch2. The D320 requires 30% less surface area than the Diamond 11.2 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 D320 weighs 6.02kg / 13.2lbs and the Wharfedale 11.2 weighs 9.00kg / 19.8lbs. This makes the Diamond 11.2 50% heavier than the D320.
