In this review, we will be comparing PerformaBe F228Be and Kendall, two Passive Floor-standing speakers from Revel and KLH. Let's have a brief look at the main features
of Revel PerformaBe F228Be 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 PerformaBe F228Be and KLH Kendall compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

PerformaBe F228Be features a 1" beryllium dome with proprietary acoustic lens waveguide Tweeter , a 5.25" Midrange and 2 x 8" DCC 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
PerformaBe F228Be has a frequency range of 27-44k Hz whereas Kendall has a frequency range of 25-23k Hz. With a minimum frequency of 25Hz, the Kendall can go slightly deeper then the PerformaBe F228Be's min frequency of 27Hz.
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
PerformaBe F228Be and Kendall have the same Impedance of 8 ohms but where they differ is the sensitivity levels. PerformaBe F228Be sensitivity is rated at 90 dB and the Kendall's is at 96 dB. This 6 dB difference makes the KLH Kendall a more sensitive speaker compared to Revel PerformaBe F228Be, 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.
PerformaBe F228Be can handle a max power of 350 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS, 350 watts less than the PerformaBe F228Be.
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 PerformaBe F228Be and Kendall 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 Revel PerformaBe F228Be's and KLH Kendall's external dimensions. Revel PerformaBe F228Be has external dimensions of 1182.0 x 301.0 x 337.0mm ( 46-1/2 x 11-13/16 x 13-1/4inch) 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 89mm narrower and 161mm shorter than Revel PerformaBe F228Be but it is also 43mm 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 Revel PerformaBe F228Be is approximately 1014.4cm2 / 157.2inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The PerformaBe F228Be requires 26% 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 PerformaBe F228Be weighs 37.27kg / 82lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the PerformaBe F228Be 68% heavier than the Kendall.
Here is a comparison of how PerformaBe F228Be and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.
