R-52C features a 1" aluminum Tractrix horn Tweeter and 2 x 5.25" 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-52C has a frequency range of 89-21k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go significantly deeper on the low side and provide stronger bass compared to the R-52C's min frequency of 89Hz.
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 Center Channel class in our database.

High Frequency
Center Channel Speakers
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-52C and R-620F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-52C sensitivity is rated at 95 dB and the R-620F's is at 96 dB. This 1 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Klipsch R-52C, 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-52C and R-620F has the same power range of up to 100 watts.
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-52C 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-52C's and Klipsch R-620F's external dimensions. Klipsch R-52C has external dimensions of 180.0 x 478.0 x 196.0mm ( 7-1/16 x 18-13/16 x 7-11/16inch) 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-52C is 841mm shorter and 173mm less deeper than Klipsch R-620F but it is also 239mm wider.
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-52C is approximately 936.9cm2 / 145.2inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The R-52C requires 6% more surface area than the R-620F which gives it a small disadvantage on placement in tight spaces.
