Aria Evo X No1 features a 1" Al/Mg inverted dome Tweeter and 1 x 6.5" Flax Woofer with a Crossover frequency at 2800 Hz. On the other hand, the 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
Aria Evo X No1 has a frequency range of 55-30kHz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 606 S2 AE can go slightly deeper then the Aria Evo X No1's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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 No1 and 606 S2 AE have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria Evo X No1 sensitivity is rated at 89.5 dB and the 606 S2 AE's is at 88 dB. This 2 dB difference makes the Focal Aria Evo X No1 a more sensitive speaker compared to B&W 606 S2, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf 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.
Both handle the same maximum of 120 watts RMS, though Aria Evo X No1 is rated 25-120 watts and 606 S2 AE 30-120 watts.
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
Both Aria Evo X No1 and 606 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 606 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Aria Evo X No1 has a front firing port whereas 606 S2 AE has a rear firing ports. Focal Aria Evo X No1's front-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 606 S2 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 No1's and B&W 606 S2's external dimensions. Focal Aria Evo X No1 has external dimensions of 391.0 x 225.0 x 280.0mm (15-3/8 x 8-⅞ x 11) whereas B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm (13-5/8 x 7-1/2 x 12-13/16inch).
B&W 606 S2 is 34mm narrower and 44mm shorter than Focal Aria Evo X No1 but it is also 46mm deeper.
Below you can see the front view size comparison of Focal Aria Evo X No1 and B&W 606 S2 in scale.

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 No1 is approximately 630.0cm2 / 97.7inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The Aria Evo X No1 requires 1% more surface area than the 606 S2 AE which gives it a small disadvantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 No1 weighs 8.50kg / 18.7lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the Aria Evo X No1 23% heavier than the 606 S2 AE.
Here is a comparison of how Aria Evo X No1 and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - Focal Aria Evo X No1 costs roughly 2.4x what B&W 606 S2 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | B&W 606 S2 digs deeper - 52Hz against 55Hz. A subwoofer would even that out. |
| Amplifier needs | A | Focal Aria Evo X No1 is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (120W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Focal Aria Evo X No1: bi-amping; B&W 606 S2: bi-amping. |
| Price | B | B&W 606 S2 is cheaper - $999 against $2,398, about 58% less; arguably a different class. |
A Focal Aria Evo X No1 B B&W 606 S2
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If your amplifier is modest, vintage or valve-based, Focal Aria Evo X No1 is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $1,399 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
