Drivers
One of the fundamental differences between these two speakers is that EVO4.2 is a 3-way design whereas the M105 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

EVO4.2 features a 1.18x2.36" AMT (Ribbon) Tweeter , a 2" Midrange and 1 x 6.5" Kevlar Woofer . On the other hand, the M105 features a 1" aluminum Hard-Dome with Acoustic Lens Waveguide Tweeter and 1 x 5.25" Aluminum Woofer with a Crossover frequency at 2300Hz.
Frequency Response
EVO4.2 has a frequency range of 54-22k Hz whereas M105 has a frequency range of 60Hz- 20kHz. With a minimum frequency of 54Hz, the EVO4.2 can go significantly deeper on the low side and provide stronger bass compared to the M105's min frequency of 60Hz.
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
EVO4.2 and M105 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.2 sensitivity is rated at 88 dB and the M105's is at 86 dB. This 2 dB difference makes the Wharfedale EVO4.2 a more sensitive speaker compared to Revel M105, 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
EVO4.2 features Post posts which make bi-amping or bi-wiring possible. M105 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
EVO4.2 has a bottom firing port whereas M105 has a rear firing ports. Wharfedale EVO4.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Revel M105 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 EVO4.2's and Revel M105's external dimensions. Wharfedale EVO4.2 has external dimensions of 455.0 x 250.0 x 350.0mm ( 17.9 x 9.8 x 13.7inch) whereas Revel M105 has external dimensions of 359.0 x 202.0 x 251.0mm ( 14-1/8 x 7-15/16 x 9-7/8inch) .
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 48mm wider, 96mm taller and 99mm deeper than Revel M105.
Below you can see the front view size comparison of Wharfedale EVO4.2 and Revel M105 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 EVO4.2 is approximately 875.0cm2 / 135.6inch2 and base area of the Revel M105 is approximately 507.0cm2 / 78.6inch2. The EVO4.2 requires 73% more surface area than the M105 which gives it a small disadvantage on placement in tight spaces.
