Denton 85 features a 1" woven textile Soft-Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 3100Hz. On the other hand, the Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Denton 85 and Diamond 225 has exactly the same frequency range of 45-20k Hz.
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.
Low Frequency

High Frequency

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
Denton 85 is a 4 ohms speaker compared to the Diamond 225 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Denton 85 can provide this impedance level.
These two speakers also have different sensitivity levels. Denton 85 sensitivity is rated at 88 dB and the Diamond 225's is rated at 87 dB. This 1 dB difference makes the Wharfedale Denton 85 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.
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 Denton 85 and Diamond 225 features dual binding post speaker terminals for bi-amping or bi-wiring.

Wharfedale 225's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Denton 85 has a rear firing port whereas Diamond 225 has a bottom firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale Denton 85 with its rear-firing port.
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 Denton 85's and Wharfedale 225's external dimensions. Wharfedale Denton 85 has external dimensions of 342.0 x 240.0 x 304.0mm ( 13-7/16 x 9-7/16 x 11-15/16inch) whereas Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) .
Wharfedale 225 is 44mm narrower and 14mm less deeper than Wharfedale Denton 85 but it is also 13mm taller.
Below you can see the front view size comparison of Wharfedale Denton 85 and Wharfedale 225 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 Denton 85 is approximately 729.6cm2 / 113.1inch2 and base area of the Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The Denton 85 requires 28% more surface area than the Diamond 225 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 Denton 85 weighs 9.00kg / 19.8lbs and the Wharfedale 225 weighs 6.55kg / 14.4lbs. This makes the Denton 85 37% heavier than the Diamond 225.
