S 809 features a 1" Tweeter and 3 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz. 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
S 809 has a frequency range of 37-26k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 37Hz, the S 809 can go slightly deeper then the R-620F'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
S 809 and R-620F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 809 sensitivity is rated at 90 dB and the R-620F's is at 96 dB. This 6 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Jamo S 809, 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.
S 809 can handle a max power of 120 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 20 watts less than the S 809.
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
S 809 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 Jamo S 809's and Klipsch R-620F's external dimensions. Jamo S 809 has external dimensions of 1042.0 x 191.0 x 252.0mm ( 41.0 x 7.5 x 9.9inch) 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) .
Jamo S 809 is 48mm narrower and 117mm less deeper than Klipsch R-620F but it is also 21mm taller.
Below you can see the front view size comparison of Jamo S 809 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 Jamo S 809 is approximately 481.3cm2 / 74.6inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The S 809 requires 45% less surface area than the R-620F 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 Jamo S 809 weighs 13.60kg / 29.9lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the R-620F 37% heavier than the S 809.
Here is a comparison of how S 809 and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.
