R-25C features a " LTS (Linear Travel Suspension) aluminum diaphragm Tractrix Horn Tweeter and 2 x 5.25" Copper spun Woofer with a Crossover frequency at 1800 Hz. On the other hand, the RP-600C features a 1" titanium Tractrix horn dome Tweeter and 2 x 6.5" Cerametallic cone Woofer .
Frequency Response
R-25C has a frequency range of 82-24K Hz whereas RP-600C has a frequency range of 58-25k Hz. With a minimum frequency of 58Hz, the RP-600C can go significantly deeper on the low side and provide stronger bass compared to the R-25C's min frequency of 82Hz.
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.

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-25C and RP-600C have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-25C sensitivity is rated at 98 dB and the RP-600C's is at 97 dB. This 1 dB difference makes the Klipsch Reference R-25C a more sensitive speaker compared to Klipsch RP-600C, 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-25C can handle a max power of 125 watts RMS from the amp the whereas R-25C has a max power handling value of 100 watts RMS , 25 watts less than the RP-600C.
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-25C features Binding post type posts and RP-600C 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 Reference R-25C's and Klipsch RP-600C's external dimensions. Klipsch Reference R-25C has external dimensions of 184 x 476 x 184mm ( 7.25 x 18.75 x 7.25-inch) whereas Klipsch RP-600C has external dimensions of 204.0 x 558.0 x 308.0mm ( 8 x 21-15/16 x 12-1/8inch) .
Klipsch RP-600C is clearly the larger of the two speakers. Its body is 82mm wider, 20mm taller and 124mm deeper than Klipsch Reference R-25C.
Below you can see the front view size comparison of Klipsch Reference R-25C and Klipsch RP-600C 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 Klipsch Reference R-25C is approximately 876.0cm2 / 135.8inch2 and base area of the Klipsch RP-600C is approximately 1718.6cm2 / 266.4inch2. The R-25C requires 49% less surface area than the RP-600C 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 Reference R-25C weighs 6.70kg / 14.7lbs and the Klipsch RP-600C weighs 10.91kg / 24lbs. This makes the RP-600C 63% heavier than the R-25C.
Here is a comparison of how R-25C and RP-600C's weights compare with the average, max and min weights in Passive Center Channel class.
