R-34C features a 1" aluminum Tractrix horn Tweeter and 4 x 3.5" copper spun IMG Woofer . On the other hand, the RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
R-34C has a frequency range of 82-21k Hz whereas RP-400M has a frequency range of 52-25k Hz. With a minimum frequency of 52Hz, the RP-400M can go significantly deeper on the low side and provide stronger bass compared to the R-34C'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-34C and RP-400M 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 RP-400M's is at 93 dB. This 3 dB difference makes the Klipsch R-34C a more sensitive speaker compared to Klipsch RP-400M, 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 can handle a max power of 100 watts RMS from the amp the whereas RP-400M has a max power handling value of 50 watts RMS, 50 watts less than the R-34C.
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 Single binding posts type posts and RP-400M has a Single binding posts 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 RP-400M'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 RP-400M has external dimensions of 298.0 x 144.0 x 191.0mm ( 11.7 x 5.6 x 7.5inch) .
Klipsch R-34C is 172mm shorter and 32mm less deeper than Klipsch RP-400M but it is also 518mm 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 RP-400M is approximately 275.0cm2 / 42.6inch2. The R-34C requires 283% more surface area than the RP-400M which gives it a small disadvantage on placement in tight spaces.
