In this review, we will be comparing Aria Evo X No2 and Concord, two Passive Floor-standing speakers from Focal and KLH. Let's have a brief look at the main features
of Focal Aria Evo X No2 and KLH Concord 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 No2 and KLH Concord 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 No2 is a 3-way design whereas the Concord 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.

Aria Evo X No2 features a 1" Al/Mg inverted dome Tweeter , a 6.5" Midrange and 2 x 6.5" Flax Woofer with a Crossover frequency at 290 Hz - 2400 Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Aria Evo X No2 has a frequency range of 45-30kHz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Aria Evo X No2's min frequency of 45Hz.
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 No2 and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X No2 sensitivity is rated at 91.5 dB and the Concord's is at 94 dB. This 2 dB difference makes the KLH Concord a more sensitive speaker compared to Focal Aria Evo X No2, 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 No2 can handle a max power of 250 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 250 watts less than the Aria Evo X No2.
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
Aria Evo X No2 features 5-Way post type posts and Concord has a 5-Way post type posts. None of these speakers 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 No2's and KLH Concord's external dimensions. Focal Aria Evo X No2 has external dimensions of 103.5 x 29.4 x 37.1 cm ( 40-¾ x 11-5/8 x 14-⅝) whereas KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm ( 40-3/8 x 8-5/16 x 14-15/16inch) .
KLH Concord is 82mm narrower and 9mm shorter than Focal Aria Evo X No2 but it is also 9mm deeper.
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 No2 is approximately 1090.7cm2 / 169.1inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Aria Evo X No2 requires 35% more surface area than the Concord 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 No2 weighs 25.00kg / 55lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Aria Evo X No2 22% heavier than the Concord.
Here is a comparison of how Aria Evo X No2 and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
