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.

Aria Evo X Center features a 1" Al/Mg inverted dome Tweeter and 2 x 6.5" Flax Woofer with a Crossover frequency at 2800 Hz. On the other hand, the 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.
Frequency Response
Aria Evo X Center has a frequency range of 57-30kHz whereas Aria Evo X No4 has a frequency range of 37-30kHz. With a minimum frequency of 37Hz, the Aria Evo X No4 can go significantly deeper on the low side and provide stronger bass compared to the Aria Evo X Center's min frequency of 57Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Aria Evo X No4 can handle a max power of 350 watts RMS, whereas Aria Evo X Center has a max power handling value of 120 watts RMS, 230 watts less than the Aria Evo X No4.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
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.
Focal Aria Evo X C's Binding post terminals allows Bi-amping or 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
The size of a speaker can sometimes be 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.
