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-34C and R-25C have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-34C sensitivity is rated at 96 dB and the R-25C's is at 98 dB. This 2 dB difference makes the Klipsch Reference R-25C a more sensitive speaker compared to Klipsch R-34C, 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-34C and R-25C 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-34C features Binding post type posts and R-25C 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-34C's and Klipsch Reference R-25C's external dimensions. Klipsch R-34C has external dimensions of 126.0 x 662.0 x 159.0mm ( 4-15/16 x 26-1/16 x 6-1/4inch) whereas Klipsch Reference R-25C has external dimensions of 184 x 476 x 184mm ( 7.25 x 18.75 x 7.25-inch) .
Klipsch R-34C is 58mm shorter and 25mm less deeper than Klipsch Reference R-25C but it is also 186mm 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-34C is approximately 1052.6cm2 / 163.2inch2 and base area of the Klipsch Reference R-25C is approximately 876.0cm2 / 135.8inch2. The R-34C requires 20% more surface area than the R-25C 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 R-34C weighs 5.91kg / 13lbs and the Klipsch Reference R-25C weighs 6.70kg / 14.7lbs. This makes the R-25C 13% heavier than the R-34C.
Here is a comparison of how R-34C and R-25C's weights compare with the average, max and min weights in Passive Center Channel class.
