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 SS-CS8 features a 1" polyester fiber Soft-Dome Tweeter and 2 x 4" Mica Reinforced Cellular (MRC) Woofer .
Frequency Response
R-25C has a frequency range of 82-24K Hz whereas SS-CS8 has a frequency range of 55-25k Hz. With a minimum frequency of 55Hz, the SS-CS8 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 is a 8 ohms speaker compared to the SS-CS8 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. R-25C sensitivity is rated at 98 dB and the SS-CS8's is rated at 86 dB. This 12 dB difference makes the Klipsch Reference R-25C a more sensitive speaker compared to Sony SS-CS8, 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 145 watts RMS from the amp the whereas R-25C has a max power handling value of 100 watts RMS , 45 watts less than the SS-CS8.
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 Post type posts and SS-CS8 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
