In this review, we will be comparing Aria Evo X No4 and Kendall, two Passive Floor-standing speakers from Focal and KLH. Let's have a brief look at the main features
of Focal Aria Evo X No4 and KLH Kendall first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Focal Aria Evo X No4 and KLH Kendall compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Aria Evo X No4 features a 1" Al/Mg inverted dome Tweeter , a 6.5" Midrange and 2 x 6.5" Flax Woofer with a Crossover frequency at 280 Hz - 2600 Hz. On the other hand, the Kendall features a 1" anodized aluminum Tweeter , a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer .
Frequency Response
Aria Evo X No4 has a frequency range of 37-30kHz whereas Kendall has a frequency range of 25-23k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the Aria Evo X No4's min frequency of 37Hz.
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 Floor-standing 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 No4 and Kendall have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X No4 sensitivity is rated at 92.5 dB and the Kendall's is at 96 dB. This 3 dB difference makes the KLH Kendall a more sensitive speaker compared to Focal Aria Evo X No4, 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 No4 can handle a max power of 350 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS, 350 watts less than the Aria Evo X No4.
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
Kendall features Binding post posts which make bi-amping or bi-wiring possible. Aria Evo X No4 has a Binding post which doesn't feature bi-amping/bi-wiring.

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 No4's and KLH Kendall's external dimensions. Focal Aria Evo X No4 has external dimensions of 115 x 37.1 x 42 cm ( 45-¼ x 14-⅝ x 16-½) whereas KLH Kendall has external dimensions of 1021.0 x 212.0 x 380.0mm ( 40-3/16 x 8-5/16 x 14-15/16inch) .
Focal Aria Evo X No4 is clearly the larger of the two speakers. Its body is 159mm wider, 129mm taller and 40mm deeper than KLH Kendall.
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 No4 is approximately 1558.2cm2 / 241.5inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The Aria Evo X No4 requires 93% more surface area than the Kendall 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 Focal Aria Evo X No4 weighs 35.00kg / 77lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the Aria Evo X No4 58% heavier than the Kendall.
Here is a comparison of how Aria Evo X No4 and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.
