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.
RP-500C II and R-52C 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
RP-500C II features Binding post type posts and R-52C has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Klipsch RP-500C II has external dimensions of 177.0 x 494.0 x 269.0mm ( 6-15/16 x 19-7/16 x 10-9/16inch) whereas 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) .
Klipsch R-52C is 16mm narrower and 73mm less deeper than Klipsch RP-500C II but it is also 3mm taller.
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 RP-500C II is approximately 1328.9cm2 / 206.0inch2 and base area of the Klipsch R-52C is approximately 936.9cm2 / 145.2inch2. The RP-500C II requires 42% more surface area than the R-52C 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 RP-500C II weighs 8.20kg / 18lbs and the Klipsch R-52C weighs 3.18kg / 7lbs. This makes the RP-500C II 158% heavier than the R-52C.
Here is a comparison of how RP-500C II and R-52C's weights compare with the average, max and min weights in Passive Center Channel class.
