What size room are the Wharfedale EVO4.2 and PSB P5 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 PSB P5 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 Alpha P5 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 Alpha P5 features a 0.75" anodized aluminum Hard-Dome Tweeter and 1 x 5.25" Polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
EVO4.2 has a frequency range of 54-22k Hz whereas Alpha P5 has a frequency range of 55-21k Hz. With a minimum frequency of 54Hz, the EVO4.2 can go slightly deeper then the Alpha P5's min frequency of 55Hz.
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
EVO4.2 and Alpha P5 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 Alpha P5's is at 89 dB. This 1 dB difference makes the PSB P5 a more sensitive speaker compared to Wharfedale EVO4.2, 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 Alpha P5 has a max power handling value of 90 watts RMS, 30 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
EVO4.2 features Binding post posts which make bi-amping or bi-wiring possible. Alpha P5 has a 5-way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
EVO4.2 has a bottom firing port whereas Alpha P5 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 PSB P5 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 PSB P5'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 PSB P5 has external dimensions of 289.0 x 172.0 x 254.0mm ( 11-3/8 x 6-3/4 x 10inch) .
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 78mm wider, 166mm taller and 96mm deeper than PSB P5.
Below you can see the front view size comparison of Wharfedale EVO4.2 and PSB P5 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 PSB P5 is approximately 436.9cm2 / 67.7inch2. The EVO4.2 requires 100% more surface area than the Alpha P5 which gives it a small disadvantage on placement in tight spaces.
