In this review, we will be comparing Concord and R-820F, two Passive Floor-standing speakers from KLH and Klipsch. Let's have a brief look at the main features
of KLH Concord and Klipsch R-820F 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 KLH Concord and Klipsch R-820F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
Both Concord and R-820F are 2-way speakers. Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer . On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .
Frequency Response
Concord has a frequency range of 28-23k Hz whereas R-820F has a frequency range of 35-21k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the R-820F's min frequency of 35Hz.
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
Concord and R-820F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Concord sensitivity is rated at 94 dB and the R-820F's is at 97 dB. This 3 dB difference makes the Klipsch R-820F a more sensitive speaker compared to KLH Concord, 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.
Concord can handle a max power of 150 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS , 150 watts less than the R-820F.
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
Concord features Post type posts and R-820F has a Post type posts. None of these speakers 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 KLH Concord's and Klipsch R-820F's external dimensions. 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) whereas Klipsch R-820F has external dimensions of 1096.0 x 277.0 x 426.0mm ( 43-1/8 x 10-7/8 x 16-3/4inch) .
Klipsch R-820F is clearly the larger of the two speakers. Its body is 65mm wider, 70mm taller and 46mm deeper than KLH Concord.
Below you can see the front view size comparison of KLH Concord and Klipsch R-820F 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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the Klipsch R-820F is approximately 1180.0cm2 / 182.9inch2. The Concord requires 32% less surface area than the R-820F 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 KLH Concord weighs 20.45kg / 45lbs and the Klipsch R-820F weighs 24.55kg / 54lbs. This makes the R-820F 20% heavier than the Concord.
Here is a comparison of how Concord and R-820F's weights compare with the average, max and min weights in Passive Floor-standing class.
