F501E features a " Tweeter and x 6" Woofer with a Crossover frequency at 250 Hz, 1700 Hz. 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
F501E has a frequency range of 36-34k 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 F501E's min frequency of 36Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
F501E and Kendall have the same Impedance of 8 ohms but where they differ is the sensitivity levels. F501E 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 Fyne Audio F501E, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Kendall can handle a max power of 250 watts RMS, whereas F501E has a max power handling value of 150 watts RMS, 100 watts less than the Kendall.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Kendall features Binding post posts which make bi-amping or bi-wiring possible. F501E has a Binding post which doesn't feature bi-amping/bi-wiring.
KLH Kendall's Binding post terminals allows Bi-amping or bi-wiring
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Fyne Audio F501E's and KLH Kendall's external dimensions. Fyne Audio F501E has external dimensions of 984.0 x 249.9 x 293.9mm (38.74 x 9.84 x 11.57inch) 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).
Fyne Audio F501E is 37mm shorter and 86.1mm less deeper than KLH Kendall but it is also 37.9mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
KLH Kendall needs about 10% more floor or shelf area. KLH Kendall is 86mm deeper, so it stands that much further out from the wall. KLH Kendall is 37mm taller.
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 Fyne Audio F501E is approximately 734.5cm2 / 113.8inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The F501E requires 9% less surface area than the Kendall 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 Fyne Audio F501E weighs 17.80kg / 39.2lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the Kendall 24% heavier than the F501E.
Here is a comparison of how F501E and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | KLH Kendall digs deeper - 25Hz against 36Hz. |
| Amplifier needs | B | KLH Kendall is more sensitive (96dB vs 90dB), so it goes louder on the same amplifier. |
| Headroom | B | KLH Kendall takes more power (250W vs 150W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | B | KLH Kendall: bi-amping. |
| Price | B | KLH Kendall is cheaper - $1,500 against $1,799, about 17% less. |
A Fyne Audio F501E B KLH Kendall
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KLH Kendall is the easier recommendation: it leads on most of the measured areas and costs less. Take Fyne Audio F501E if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 36Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, KLH Kendall is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
