In this review, we will be comparing F502S and Concord, two Passive Floor-standing speakers from Fyne Audio and KLH.
Let's have a brief look at the main features
of Fyne Audio F502S and KLH Concord first before getting into our more
detailed comparison.

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that F502S is a 3-way design whereas the Concord is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

F502S features a " Tweeter and x 8" Woofer with a Crossover frequency at 250 Hz, 1700 Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
F502S has a frequency range of 30-34k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the F502S's min frequency of 30Hz.
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
F502S and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. F502S sensitivity is rated at 91 dB and the Concord's is at 94 dB. This 3 dB difference makes the KLH Concord a more sensitive speaker compared to Fyne Audio F502S, 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.
Concord can handle a max power of 225 watts RMS, whereas F502S has a max power handling value of 180 watts RMS, 45 watts less than the Concord.
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.

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
F502S features 5-Way post type posts and Concord has a 5-Way post type posts. None of these speakers feature bi-amping/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 F502S's and KLH Concord's external dimensions. Fyne Audio F502S has external dimensions of 1112.5 x 299.7 x 381.0mm (43.8 x 11.8 x 15inch) whereas KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm (40-3/8 x 8-5/16 x 14-15/16inch).
Fyne Audio F502S is clearly the larger of the two speakers. Its body is 87.7mm wider, 86.5mm taller and 1mm deeper than KLH Concord.
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.
Fyne Audio F502S needs about 42% more floor or shelf area. Fyne Audio F502S is 87mm 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 F502S is approximately 1141.9cm2 / 177.0inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The F502S requires 42% more surface area than the Concord 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 Fyne Audio F502S weighs 28.49kg / 62.7lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the F502S 39% heavier than the Concord.
Here is a comparison of how F502S and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Fyne Audio F502S costs roughly 3.5x what KLH Concord does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (30Hz vs 28Hz). |
| Amplifier needs | B | KLH Concord is more sensitive (94dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | B | KLH Concord takes more power (225W vs 180W) - more in hand in a big room. |
| Size | depends | KLH Concord is easier to place; Fyne Audio F502S is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | KLH Concord is cheaper - $1,000 against $3,499, about 71% less; arguably a different class. |
A Fyne Audio F502S B KLH Concord
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 Concord is the easier recommendation: it leads on most of the measured areas and costs less. Take Fyne Audio F502S if its size, looks or fit in your room suit you better. In a large or open-plan room, Fyne Audio F502S has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Concord is the easier speaker to get right. If your amplifier is modest, vintage or valve-based, KLH Concord 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.
