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 RP-400C have the same Impedance of 8 ohms and their sensitivity is also same at 95 dB.
Sensitivity

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 can handle a max power of 100 watts RMS from the amp the whereas RP-400C has a max power handling value of 75 watts RMS, 25 watts less than the R-52C.
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 Binding post type posts and RP-400C has a Binding 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 RP-400C'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 RP-400C has external dimensions of 147.0 x 408.0 x 242.0mm ( 5-3/4 x 16-1/16 x 9-1/2inch) .
Klipsch RP-400C is 70mm narrower and 33mm shorter than Klipsch R-52C but it is also 46mm deeper.
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 RP-400C is approximately 987.4cm2 / 153.0inch2. The R-52C requires 5% less surface area than the RP-400C 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 Klipsch R-52C weighs 3.18kg / 7lbs and the Klipsch RP-400C weighs 6.36kg / 14lbs. This makes the RP-400C 100% heavier than the R-52C.
Here is a comparison of how R-52C and RP-400C's weights compare with the average, max and min weights in Passive Center Channel class.
