In this review, we will be comparing F36 and Kendall, two Passive Floor-standing speakers from Revel and KLH. Let's have a brief look at the main features
of Revel Concerta2 F36 and KLH Kendall 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 Revel Concerta2 F36 and KLH Kendall compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

F36 features a 1" aluminum dome with with proprietary acoustic lens and waveguide Tweeter , a 6.5" Midrange and 2 x 6.5" Anodized aluminum Woofer . On the other hand, the Kendall features a 1" anodized aluminum Tweeter , a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer .
Frequency Response
F36 has a frequency range of 51- Hz whereas Kendall has a frequency range of 25-23k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the F36's min frequency of 51Hz.
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
F36 is a 6 ohms speaker compared to the Kendall which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. F36 sensitivity is rated at 91 dB and the Kendall's is rated at 96 dB. This 5 dB difference makes the KLH Kendall a more sensitive speaker compared to Revel Concerta2 F36, 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.
F36 can handle a max power of 200 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS, 200 watts less than the F36.
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
Kendall features Binding post posts which make bi-amping or bi-wiring possible. F36 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
KLH Kendall'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 Revel Concerta2 F36's and KLH Kendall's external dimensions. Revel Concerta2 F36 has external dimensions of 1126.0 x 247.0 x 361.0mm ( 44-5/16 x 9-11/16 x 14-3/16inch) whereas 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) .
KLH Kendall is 35mm narrower and 105mm shorter than Revel Concerta2 F36 but it is also 19mm deeper.
Below you can see the front view size comparison of Revel Concerta2 F36 and KLH Kendall 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 Revel Concerta2 F36 is approximately 891.7cm2 / 138.2inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The F36 requires 11% more surface area than the Kendall 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 Revel Concerta2 F36 weighs 22.73kg / 50lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the F36 3% heavier than the Kendall.
Here is a comparison of how F36 and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.
