In this review, we will be comparing R5 Meta and Concord, two Passive Floor-standing speakers from KEF and KLH. Let's have a brief look at the main features
of KEF R5 Meta and KLH Concord 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 KEF R5 Meta and KLH Concord compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that R5 Meta 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.

R5 Meta features a 1" Aluminum with MAT absorber Vented dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2700Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
R5 Meta has a frequency range of 52-28k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the R5 Meta's min frequency of 52Hz.
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
R5 Meta is a 4 ohms speaker compared to the Concord which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the R5 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. R5 Meta sensitivity is rated at 87 dB and the Concord's is rated at 94 dB. This 7 dB difference makes the KLH Concord a more sensitive speaker compared to KEF R5 Meta, 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.
R5 Meta can handle a max power of 200 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 200 watts less than the R5 Meta.
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
R5 Meta features Custom 5-way bi-wire tool-less binding posts posts which make bi-amping or bi-wiring possible. Concord has a 5-Way post which doesn't feature bi-amping/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 KEF R5 Meta's and KLH Concord's external dimensions. KEF R5 Meta has external dimensions of 1074.0 x 274.0 x 343.0mm ( 42-1/4-inch x 10-3/4-inch x 13-1/2-inch) 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) .
KLH Concord is 62mm narrower and 48mm shorter than KEF R5 Meta but it is also 37mm deeper.
Below you can see the front view size comparison of KEF R5 Meta and KLH Concord 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 KEF R5 Meta is approximately 939.8cm2 / 145.7inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The R5 Meta requires 17% 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 KEF R5 Meta weighs 24.55kg / 54lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the R5 Meta 20% heavier than the Concord.
Here is a comparison of how R5 Meta and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
