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 936 features a 1" TNF Al/Mg inverted dome Tweeter , a 6.5" Midrange and 3 x 6.5" Flax Woofer with a Crossover frequency at 260Hz and 3,100Hz.
Frequency Response
R7 has a frequency range of 48-28k Hz whereas Aria 936 has a frequency range of 39-28k Hz. With a minimum frequency of 39Hz, the Aria 936 can go significantly deeper on the low side and provide stronger bass compared to the R7's min frequency of 48Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
R7 and Aria 936 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 936's is at 92 dB. This 4 dB difference makes the Focal Aria 936 a more sensitive speaker compared to KEF R7, 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. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
R7 can handle a max power of 300 watts RMS from the amp the whereas R7 has a max power handling value of 250 watts RMS , 50 watts less than the Aria 936.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
R7 features Binding post posts which make bi-amping or bi-wiring possible. Aria 936 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
Size of a speaker can sometimes become 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 936'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 936 has external dimensions of 1148.0 x 294.0 x 374.0mm ( 45-3/16 x 11-9/16 x 14-11/16inch) .
KEF R7 is 94mm narrower and 35mm shorter than Focal Aria 936 but it is also 15mm deeper.
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 936 is approximately 1099.6cm2 / 170.4inch2. The R7 requires 29% less surface area than the Aria 936 which gives it a small advantage on placement in tight spaces.
