R-34C features a 1" aluminum Tractrix horn Tweeter and 4 x 3.5" copper spun IMG Woofer . On the other hand, the Monitor XT30 features a 1" Terylene High-res dome Tweeter and 2 x 5.25" bi-laminate paper cone Woofer .
Frequency Response
R-34C has a frequency range of 82-21k Hz whereas Monitor XT30 has a frequency range of 55-40k Hz. With a minimum frequency of 55Hz, the Monitor XT30 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 Monitor XT30 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 Monitor XT30's is at 89 dB. This 7 dB difference makes the Klipsch R-34C a more sensitive speaker compared to Polk XT30, 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 200 watts RMS from the amp the whereas R-34C has a max power handling value of 100 watts RMS , 100 watts less than the Monitor XT30.
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 5-Way post type posts and Monitor XT30 has a 5-Way 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 Polk XT30'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 Polk XT30 has external dimensions of 166.0 x 485.0 x 208.0mm ( 6-1/2 x 19-1/16 x 8-3/16inch) .
Klipsch R-34C is 40mm shorter and 49mm less deeper than Polk XT30 but it is also 177mm 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 Polk XT30 is approximately 1008.8cm2 / 156.4inch2. The R-34C requires 4% more surface area than the Monitor XT30 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 Polk XT30 weighs 5.91kg / 13lbs.
Here is a comparison of how R-34C and Monitor XT30's weights compare with the average, max and min weights in Passive Center Channel class.
