What size room are the KEF R7 and Focal Aria 926 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

R7 features a 1" aluminum Dome Tweeter, a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz. On the other hand, the Aria 926 features a 1" TNF Al/Mg inverted dome Tweeter, a 6.5" Midrange and 2 x 6.5" Flax Woofer with a Crossover frequency at 290Hz and 2,400Hz.
Frequency Response
R7 has a frequency range of 48-28k Hz whereas Aria 926 has a frequency range of 45-28k Hz. With a minimum frequency of 45Hz, the Aria 926 can go slightly deeper then the R7's min frequency of 48Hz.
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
R7 and Aria 926 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R7 sensitivity is rated at 88 dB and the Aria 926's is at 91.5 dB. This 4 dB difference makes the Focal Aria 926 a more sensitive speaker compared to KEF R7, 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.
Both handle the same maximum of 250 watts RMS, though R7 is rated 15-250 watts and Aria 926 40-250 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
R7 features Binding post posts which make bi-amping or bi-wiring possible. Aria 926 has a Binding post which doesn't feature bi-amping/bi-wiring.
KEF R7's Binding post terminals allows Bi-amping or 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 KEF R7's and Focal Aria 926's external dimensions. KEF R7 has external dimensions of 1113.0 x 200.0 x 389.0mm (43-13/16 x 8 x 15-5/16inch) 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).
Focal Aria 926 is 74mm shorter and 15mm less deeper than KEF R7 but it is also 94mm 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 KEF R7 is approximately 778.0cm2 / 120.6inch2 and base area of the Focal Aria 926 is approximately 1099.6cm2 / 170.4inch2. The R7 requires 29% less surface area than the Aria 926 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 KEF R7 weighs 31.40kg / 69.1lbs and the Focal Aria 926 weighs 25.00kg / 55lbs. This makes the R7 26% heavier than the Aria 926.
Here is a comparison of how R7 and Aria 926's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: KEF R7 is the newer design, against a 2013 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | Focal Aria 926 digs deeper - 45Hz against 48Hz. A subwoofer would even that out. |
| Amplifier needs | B | Focal Aria 926 is more sensitive (92dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | evenly matched | Similar power handling (250W vs 250W). |
| Size | depends | KEF R7 is easier to place; Focal Aria 926 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | KEF R7: bi-amping. |
| Price | evenly matched | Much the same money ($4,500 vs $4,798 a pair). |
A KEF R7 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 926 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If your amplifier is modest, vintage or valve-based, Focal Aria 926 is the safer partner - the other will want more current or more watts to sound its best.
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.
