R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer . On the other hand, the R-625FA features a 1" 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-625FA has a frequency range of 38-21k Hz. With a minimum frequency of 35Hz, the R-820F can go slightly deeper then the R-625FA's min frequency of 38Hz.
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-625FA 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-625FA's is at 96 dB. This 1 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Klipsch R-625FA, 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-625FA 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-625FA 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-625FA'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-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm ( 40-3/16 x 9-3/8 x 16-3/4inch) .
Klipsch R-625FA is 38mm narrower and 75mm shorter than Klipsch R-820F but they have the same thickness of 426.0mm.
Below you can see the front view size comparison of Klipsch R-820F and Klipsch R-625FA 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 1180.0cm2 / 182.9inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The R-820F requires 16% more surface area than the R-625FA 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-625FA weighs 22.20kg / 48.8lbs. This makes the R-820F 11% heavier than the R-625FA.
Here is a comparison of how R-820F and R-625FA's weights compare with the average, max and min weights in Passive Floor-standing class.
