In this review, we will be comparing EVO4.1 and Q350, two Passive Bookshelf speakers from Wharfedale and KEF. Let's have a brief look at the main features
of Wharfedale EVO4.1 and KEF Q350 first before getting into our more
What size room are the Wharfedale EVO4.1 and KEF Q350 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:
In the following sections, we will get into more detail in order to better understand how the Wharfedale EVO4.1 and KEF Q350 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both EVO4.1 and Q350 are 2-way speakers.
1 x 5-inch
1 x 6.5-inch
EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer . On the other hand, the Q350 features a 1" vented aluminum Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz.
EVO4.1 has a frequency range of 64-22k Hz whereas Q350 has a frequency range of 63-28k Hz. With a minimum frequency of 63Hz, the Q350 can go slightly deeper then the EVO4.1's min frequency of 64Hz.
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
EVO4.1 and Q350 have the same Impedance of 8 ohms and their sensitivity is also same at 87 dB.
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.
EVO4.1 can handle a max power of 120 watts RMS from the amp the whereas EVO4.1 has a max power handling value of 100 watts RMS , 20 watts less than the Q350.
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
EVO4.1 features Post posts which make bi-amping or bi-wiring possible. Q350 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
EVO4.1 has a bottom firing port whereas Q350 has a rear firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF Q350 with its rear-firing port.
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 EVO4.1's and KEF Q350's external dimensions. Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm ( 13.1 x 8.2 x 11.6inch) whereas KEF Q350 has external dimensions of 358.0 x 210.0 x 306.0mm ( 14.0 x 8.2 x 12.0inch) .
Below you can see the front view size comparison of Wharfedale EVO4.1 and KEF Q350 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 EVO4.1 is approximately 619.5cm2 / 96.0inch2 and base area of the KEF Q350 is approximately 642.6cm2 / 99.6inch2. The EVO4.1 requires 4% less surface area than the Q350 which gives it a small advantage 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:
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 EVO4.1 weighs 7.80kg / 17.2lbs and the KEF Q350 weighs 7.60kg / 16.7lbs. This makes the EVO4.1 3% heavier than the Q350.
Here is a comparison of how EVO4.1 and Q350's weights compare with the average, max and min weights in Passive Bookshelf class.
