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 K2 936K2 and Aria 926 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Aria K2 936K2 sensitivity is rated at 92 dB and the Aria 926's is at 91.5 dB.
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 K2 936K2 can handle a max power of 300 watts RMS, whereas Aria 926 has a max power handling value of 250 watts RMS, 50 watts less than the Aria K2 936K2.
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 K2 936K2 features Binding post type posts and Aria 926 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

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 K2 936K2's and Focal Aria 926's external dimensions. Focal Aria K2 936K2 has external dimensions of 1148.0 x 294.0 x 374.0mm (45-3/16 x 11-9/16 x 14-11/16inch) whereas Focal Aria 926 has external dimensions of 1039.0 x 294.0 x 374.0mm (40-7/8 x 11-9/16 x 14-11/16inch).
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 K2 936K2 is approximately 1099.6cm2 / 170.4inch2 and base area of the Focal Aria 926 is approximately 1099.6cm2 / 170.4inch2.
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 K2 936K2 weighs 29.09kg / 64lbs and the Focal Aria 926 weighs 25.00kg / 55lbs. This makes the Aria K2 936K2 16% heavier than the Aria 926.
Here is a comparison of how Aria K2 936K2 and Aria 926's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Focal's Aria series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Focal Aria K2 936K2 digs deeper - 39Hz against 45Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (92dB vs 92dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (300W vs 250W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Price | B | Focal Aria 926 is cheaper - $4,798 against $6,598, about 27% less. |
A Focal Aria K2 936K2 B Focal Aria 926
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?
Focal Aria K2 936K2 is ahead, but only on 1 of the measured areas, and it costs about 38% more. That is a lot of money for a narrow margin on paper - Focal Aria 926 looks like the sensible buy unless something else about the Focal Aria K2 936K2 appeals to you. 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 926 much easier to justify. Think about the whole system, not just the speakers: the roughly $1,800 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.
