What size room are the Wharfedale 225 and Wharfedale 11.2 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

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 Diamond 11.2 features a 1" Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer .
Frequency Response
Diamond 225 has a frequency range of 45-20k Hz whereas Diamond 11.2 has a frequency range of 48-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go slightly deeper then the Diamond 11.2'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 Diamond 11.2 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 Diamond 11.2's is at 88 dB. This 1 dB difference makes the Wharfedale 11.2 a more sensitive speaker compared to Wharfedale 225, 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 125 watts RMS from the amp the whereas Diamond 225 has a max power handling value of 120 watts RMS , 5 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
Diamond 225 features Post posts which make bi-amping or bi-wiring possible. Diamond 11.2 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Diamond 225 and Diamond 11.2 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 11.2'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 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 27mm wider, 1mm taller and 31mm deeper than Wharfedale 225.
Below you can see the front view size comparison of Wharfedale 225 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 225 is approximately 568.4cm2 / 88.1inch2 and base area of the Wharfedale 11.2 is approximately 715.8cm2 / 110.9inch2. The Diamond 225 requires 21% 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 225 weighs 6.55kg / 14.4lbs and the Wharfedale 11.2 weighs 9.00kg / 19.8lbs. This makes the Diamond 11.2 37% heavier than the Diamond 225.
Here is a comparison of how Diamond 225 and Diamond 11.2's weights compare with the average, max and min weights in Passive Bookshelf class.
