Drivers
One of the fundamental differences between these two speakers is that C 97 II is a 3-way design whereas the R-820F is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer . On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .
Frequency Response
C 97 II has a frequency range of 32-24k Hz whereas R-820F has a frequency range of 35-21k Hz. With a minimum frequency of 32Hz, the C 97 II 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
C 97 II is a 6 ohms speaker compared to the R-820F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. C 97 II sensitivity is rated at 89 dB and the R-820F's is rated at 97 dB. This 8 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Jamo C 97 II, 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.
C 97 II can handle a max power of 180 watts RMS from the amp the whereas R-820F has a max power handling value of 150 watts RMS, 30 watts less than the C 97 II.
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
C 97 II features Posts posts which make bi-amping or bi-wiring possible. R-820F has a Post which doesn't 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 C 97 II's and Klipsch R-820F's external dimensions. Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm ( 42-1/8 x 9-3/4 x 15-13/16inch) 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 29mm wider, 26mm taller and 24mm deeper than Jamo C 97 II.
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 C 97 II is approximately 997.0cm2 / 154.5inch2 and base area of the Klipsch R-820F is approximately 1180.0cm2 / 182.9inch2. The C 97 II requires 16% 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 Jamo C 97 II weighs 24.55kg / 54lbs and the Klipsch R-820F weighs 24.55kg / 54lbs.
Here is a comparison of how C 97 II and R-820F's weights compare with the average, max and min weights in Passive Floor-standing class.
