Drivers
One of the fundamental differences between these two speakers is that Aria Evo X Center is a 2-way design whereas the Aria Evo X No4 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.

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 Center and Aria Evo X No4 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X Center sensitivity is rated at 91 dB and the Aria Evo X No4's is at 92.5 dB. This 2 dB difference makes the Focal Aria Evo X No4 a more sensitive speaker compared to Focal Aria Evo X C, 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 Center can handle a max power of 350 watts RMS from the amp the whereas Aria Evo X Center has a max power handling value of 120 watts RMS , 230 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
Aria Evo X Center 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.

Cabinet Type and Port Position
Aria Evo X Center has a rear firing port whereas Aria Evo X No4 has a front firing ports. Focal Aria Evo X No4's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Focal Aria Evo X C 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 C's and Focal Aria Evo X No4's external dimensions. Focal Aria Evo X C has external dimensions of 20 x 53.3 x 24.5 cm ( 7-7/8 x 21 x 9-5/8) whereas Focal Aria Evo X No4 has external dimensions of 115 x 37.1 x 42 cm ( 45-¼ x 14-⅝ x 16-½) .
Focal Aria Evo X C is 950mm shorter and 175mm less deeper than Focal Aria Evo X No4 but it is also 162mm wider.
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 C is approximately 1305.9cm2 / 202.4inch2 and base area of the Focal Aria Evo X No4 is approximately 1558.2cm2 / 241.5inch2. The Aria Evo X Center requires 16% less surface area than the Aria Evo X No4 which gives it a small advantage on placement in tight spaces.
