What size room are the Wharfedale EVO4.2 and Wharfedale Reva 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Wharfedale EVO4.2 and Wharfedale Reva 2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that EVO4.2 is a 3-way design whereas the Reva 2 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 Reva 2 features a 1" woven textile Dome Tweeter and 1 x 5" Woven Glass Fiber Woofer .
Frequency Response
EVO4.2 has a frequency range of 54-22k Hz whereas Reva 2 has a frequency range of 48-20k Hz. With a minimum frequency of 48Hz, the Reva 2 can go significantly deeper on the low side and provide stronger bass compared to the EVO4.2's min frequency of 54Hz.
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 Reva 2 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 Reva 2's is at 86 dB. This 2 dB difference makes the Wharfedale EVO4.2 a more sensitive speaker compared to Wharfedale Reva 2, 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.
EVO4.2 can handle a max power of 120 watts RMS from the amp the whereas Reva 2 has a max power handling value of 80 watts RMS, 40 watts less than the EVO4.2.
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
Both EVO4.2 and Reva 2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale Reva 2's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both EVO4.2 and Reva 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 EVO4.2's and Wharfedale Reva 2'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 Wharfedale Reva 2 has external dimensions of 358.0 x 201.0 x 326.0mm ( 14-1/16 x 7-7/8 x 12-13/16inch) .
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 49mm wider, 97mm taller and 24mm deeper than Wharfedale Reva 2.
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 Wharfedale Reva 2 is approximately 655.3cm2 / 101.6inch2. The EVO4.2 requires 34% more surface area than the Reva 2 which gives it a small disadvantage 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 EVO4.2 weighs 13.40kg / 29.5lbs and the Wharfedale Reva 2 weighs 7.82kg / 17.2lbs. This makes the EVO4.2 71% heavier than the Reva 2.
Here is a comparison of how EVO4.2 and Reva 2's weights compare with the average, max and min weights in Passive Bookshelf class.
