In this review, we will be comparing Kendall and R11, two Passive Floor-standing speakers from KLH and KEF. Let's have a brief look at the main features
of KLH Kendall and KEF R11 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the KLH Kendall and KEF R11 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Kendall features a 1" anodized aluminum Tweeter , a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer . On the other hand, the R11 features a 1" aluminum Dome Tweeter , a 5" Midrange and 4 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 R11 has a frequency range of 46-28k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the R11's min frequency of 46Hz.
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.

High Frequency

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 R11 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kendall sensitivity is rated at 96 dB and the R11's is at 90 dB. This 6 dB difference makes the KLH Kendall a more sensitive speaker compared to KEF R11, 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. 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 300 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS , 300 watts less than the R11.
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 R11 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 R11'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 R11 has external dimensions of 1301.0 x 312.0 x 389.0mm ( 51-3/16 x 12-1/4 x 15-5/16inch) .
KEF R11 is clearly the larger of the two speakers. Its body is 100mm wider, 280mm taller and 9mm deeper than KLH Kendall.
Below you can see the front view size comparison of KLH Kendall and KEF R11 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 R11 is approximately 1213.7cm2 / 188.1inch2. The Kendall requires 34% less surface area than the R11 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 KLH Kendall weighs 22.14kg / 48.7lbs and the KEF R11 weighs 37.70kg / 82.9lbs. This makes the R11 70% heavier than the Kendall.
Here is a comparison of how Kendall and R11's weights compare with the average, max and min weights in Passive Floor-standing class.
