Kendall features a 1" anodized aluminum Tweeter , a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer . On the other hand, the 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.
Frequency Response
Kendall has a frequency range of 25-23k Hz whereas R7 has a frequency range of 48-28k Hz. With a minimum frequency of 25Hz, the Kendall 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.
Low Frequency

High Frequency
Floor-standing Speakers
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
Kendall and R7 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kendall sensitivity is rated at 96 dB and the R7's is at 88 dB. This 8 dB difference makes the KLH Kendall 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.
Kendall can handle a max power of 250 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS , 250 watts less than the R7.
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
Both Kendall and R7 features dual binding post speaker terminals for 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 KLH Kendall's and KEF R7's external dimensions. KLH Kendall has external dimensions of 1021.0 x 212.0 x 380.0mm ( 40-3/16 x 8-5/16 x 14-15/16inch) whereas KEF R7 has external dimensions of 1113.0 x 200.0 x 389.0mm ( 43-13/16 x 8 x 15-5/16inch) .
KLH Kendall is 92mm shorter and 9mm less deeper than KEF R7 but it is also 12mm wider.
Below you can see the front view size comparison of KLH Kendall and KEF R7 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 KLH Kendall is approximately 805.6cm2 / 124.9inch2 and base area of the KEF R7 is approximately 778.0cm2 / 120.6inch2. The Kendall requires 4% more surface area than the R7 which gives it a small disadvantage 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 KLH Kendall weighs 22.14kg / 48.7lbs and the KEF R7 weighs 31.40kg / 69.1lbs. This makes the R7 42% heavier than the Kendall.
Here is a comparison of how Kendall and R7's weights compare with the average, max and min weights in Passive Floor-standing class.
