In this review, we will be comparing R-820F and R-620F, two Passive Floor-standing speakers by Klipsch Let's have a brief look at the main features
of Klipsch R-820F and Klipsch R-620F first before getting into our more
detailed comparison.
R-820F and R-620F are members of Klipsch's Reference (R) series of speakers. Below you can find the loudspeakers from this series.

What size room are the Klipsch R-820F and Klipsch R-620F speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Klipsch R-820F and Klipsch R-620F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
Both R-820F and R-620F are 2-way speakers. R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer . On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
R-820F has a frequency range of 35-21k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go slightly deeper then 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
R-820F and R-620F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-820F sensitivity is rated at 97 dB and the R-620F's is at 96 dB. This 1 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Klipsch R-620F, 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.
R-820F can handle a max power of 150 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 50 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
R-820F features Post type posts and R-620F 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 Klipsch R-820F's and Klipsch R-620F's external dimensions. 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) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm ( 40-3/16 x 9-3/8 x 14-1/2inch) .
Klipsch R-820F is clearly the larger of the two speakers. Its body is 38mm wider, 75mm taller and 57mm deeper than Klipsch R-620F.
Below you can see the front view size comparison of Klipsch R-820F and Klipsch R-620F 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 Klipsch R-820F is approximately 1180.0cm^{2} / 182.9inch^{2} and base area of the Klipsch R-620F is approximately 881.9cm^{2} / 136.7inch^{2}. The R-820F requires 34% more surface area than the R-620F 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 Klipsch R-820F weighs 24.55kg / 54lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the R-820F 32% heavier than the R-620F.
Here is a comparison of how R-820F and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.
