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 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 No2 has a frequency range of 45-30kHz 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 No2's min frequency of 45Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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 No2 and Aria Evo X No4 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 Aria Evo X No4's is at 92.5 dB. This 1 dB difference makes the Focal Aria Evo X No4 a more sensitive speaker compared to Focal Aria Evo X No2, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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 No2 has a max power handling value of 250 watts RMS, 100 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.
Which plays louder on your 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 No2 features Binding post type posts and Aria Evo X No4 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Aria Evo X No2 and Aria Evo X No4 have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 No2's and Focal Aria Evo X No4'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 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 No4 is clearly the larger of the two speakers. Its body is 77mm wider, 115mm taller and 49mm deeper than Focal Aria Evo X No2.
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 Focal Aria Evo X No4 is approximately 1558.2cm2 / 241.5inch2. The Aria Evo X No2 requires 30% less surface area than the Aria Evo X No4 which gives it a small advantage 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 Focal Aria Evo X No4 weighs 35.00kg / 77lbs. This makes the Aria Evo X No4 40% heavier than the Aria Evo X No2.

Siblings in Focal's Aria Evo X series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Focal Aria Evo X No4 digs deeper - 37Hz against 45Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (92dB vs 93dB) - both want much the same power. |
| Headroom | B | Focal Aria Evo X No4 takes more power (350W vs 250W) - more in hand in a big room. |
| Size | depends | Focal Aria Evo X No2 is easier to place; Focal Aria Evo X No4 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Focal Aria Evo X No2 is cheaper - $4,798 against $5,998, about 20% less. |
A Focal Aria Evo X No2 B Focal Aria Evo X No4
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Focal Aria Evo X No4 measures better, Focal Aria Evo X No2 costs about about 25% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 45Hz anyway, which makes the cheaper Focal Aria Evo X No2 much easier to justify. Match it to your room: we rate Focal Aria Evo X No4 the better fit for a very large room; elsewhere the two are rated the same.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
