Diamond 12.1 features a 1" Textile Soft-Dome Tweeter and 1 x 5" Mica-infused polypropylene Woofer with a Crossover frequency at 2600Hz. On the other hand, the EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer .
Frequency Response
Diamond 12.1 has a frequency range of 65-20k Hz whereas EVO4.1 has a frequency range of 64-22k Hz. With a minimum frequency of 64Hz, the EVO4.1 can go slightly deeper then the Diamond 12.1'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.

High Frequency
Bookshelf Speakers
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 12.1 and EVO4.1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 12.1 sensitivity is rated at 88 dB and the EVO4.1's is at 87 dB. This 1 dB difference makes the Wharfedale 12.1 a more sensitive speaker compared to Wharfedale EVO4.1, 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 Diamond 12.1 and EVO4.1 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale EVO4.1's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Diamond 12.1 has a rear firing port whereas EVO4.1 has a bottom firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale 12.1 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 12.1's and Wharfedale EVO4.1's external dimensions. Wharfedale 12.1 has external dimensions of 312.0 x 180.0 x 278.0mm ( 12.2 x 7.0 x 10.9inch) whereas Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm ( 13.1 x 8.2 x 11.6inch) .
Wharfedale EVO4.1 is clearly the larger of the two speakers. Its body is 30mm wider, 23mm taller and 17mm deeper than Wharfedale 12.1.
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 12.1 is approximately 500.4cm2 / 77.6inch2 and base area of the Wharfedale EVO4.1 is approximately 619.5cm2 / 96.0inch2. The Diamond 12.1 requires 19% less surface area than the EVO4.1 which gives it a small advantage on placement in tight spaces.
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 12.1 weighs 6.80kg / 15lbs and the Wharfedale EVO4.1 weighs 7.80kg / 17.2lbs. This makes the EVO4.1 15% heavier than the Diamond 12.1.
Here is a comparison of how Diamond 12.1 and EVO4.1's weights compare with the average, max and min weights in Passive Bookshelf class.
