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.
In the following sections, we will get into details in order to better understand how Klipsch R-820F and Klipsch R-620F compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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, R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
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 under Floor-standing class in our database.
Impedance and Sensitivity
R-820F and R-620F has the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-820F sensitivity is rated at 97 dB and R-620F's is at 96 dB. This 1 dB difference makes Klipsch R-820F a more sensitive speaker compared to Klipsch R-620F, hence will play louder with the same amount of watts.
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 higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, 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.
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.
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-620F is approximately 881.9cm2 / 136.7inch2. The R-820F requires 34% more surface area than the R-620F which gives it a small disadvantage on placement in tight spaces.
