In this review, we will be comparing Aria Evo X No1 and R3, two Passive Bookshelf speakers from Focal and KEF. Let's have a brief look at the main features
of Focal Aria Evo X No1 and KEF R3 first before getting into our more
detailed comparison.
What size room are the Focal Aria Evo X No1 and KEF R3 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 Focal Aria Evo X No1 and KEF R3 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 Aria Evo X No1 is a 2-way design whereas the R3 is a 3-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.

Aria Evo X No1 features a 1" Al/Mg inverted dome Tweeter and 1 x 6.5" Flax Woofer with a Crossover frequency at 2800 Hz. On the other hand, the R3 features a 1" aluminum Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
Aria Evo X No1 has a frequency range of 55-30kHz whereas R3 has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the R3 can go slightly deeper then the Aria Evo X No1'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.

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
Aria Evo X No1 and R3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X No1 sensitivity is rated at 89.5 dB and the R3's is at 87 dB. This 3 dB difference makes the Focal Aria Evo X No1 a more sensitive speaker compared to KEF R3, 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.
Aria Evo X No1 can handle a max power of 180 watts RMS from the amp the whereas Aria Evo X No1 has a max power handling value of 120 watts RMS , 60 watts less than the R3.
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 Aria Evo X No1 and R3 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Aria Evo X No1 has a front firing port whereas R3 has a rear firing ports. Focal Aria Evo X No1's front-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF R3 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 Focal Aria Evo X No1's and KEF R3's external dimensions. Focal Aria Evo X No1 has external dimensions of 39 x 22.5 x 28 cm ( 15-3/8 x 8-⅞ x 11) whereas KEF R3 has external dimensions of 423.0 x 199.0 x 337.0mm ( 16-5/8 x 7-13/16 x 13-1/4inch) .
Focal Aria Evo X No1 is 32mm shorter and 57mm less deeper than KEF R3 but it is also 26mm wider.
Below you can see the front view size comparison of Focal Aria Evo X No1 and KEF R3 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 Focal Aria Evo X No1 is approximately 630.0cm2 / 97.7inch2 and base area of the KEF R3 is approximately 670.6cm2 / 103.9inch2. The Aria Evo X No1 requires 6% less surface area than the R3 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:

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 Focal Aria Evo X No1 weighs 8.50kg / 18.7lbs and the KEF R3 weighs 13.55kg / 29.8lbs. This makes the R3 59% heavier than the Aria Evo X No1.
Here is a comparison of how Aria Evo X No1 and R3's weights compare with the average, max and min weights in Passive Bookshelf class.
