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 11.1 and D320 has the same power range of 25-100 watts.
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 11.1 features Post type posts and D320 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Diamond 11.1 and D320 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 11.1's and Wharfedale D320's external dimensions. Wharfedale 11.1 has external dimensions of 312.0 x 196.0 x 316.0mm ( 12-1/4 x 7-11/16 x 12-7/16inch) whereas 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) .
Wharfedale D320 is 15mm narrower and 39mm less deeper than Wharfedale 11.1 but it is also 9mm taller.
Below you can see the front view size comparison of Wharfedale 11.1 and Wharfedale D320 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 11.1 is approximately 619.4cm2 / 96.0inch2 and base area of the Wharfedale D320 is approximately 501.4cm2 / 77.7inch2. The Diamond 11.1 requires 24% more surface area than the D320 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 11.1 weighs 6.81kg / 15lbs and the Wharfedale D320 weighs 6.02kg / 13.2lbs. This makes the Diamond 11.1 13% heavier than the D320.
Here is a comparison of how Diamond 11.1 and D320's weights compare with the average, max and min weights in Passive Bookshelf class.
