Monitor XT35 features a 1" Terylene High-res dome Tweeter and 4 x 3" bi-laminate paper cone Woofer . On the other hand, the R-34C features a 1" aluminum Tractrix horn Tweeter and 4 x 3.5" copper spun IMG Woofer .
Frequency Response
Monitor XT35 has a frequency range of 57-40k Hz whereas R-34C has a frequency range of 82-21k Hz. With a minimum frequency of 57Hz, the Monitor XT35 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
Monitor XT35 and R-34C have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Monitor XT35 sensitivity is rated at 87 dB and the R-34C's is at 96 dB. This 9 dB difference makes the Klipsch R-34C a more sensitive speaker compared to Polk XT35, 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.
Monitor XT35 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 XT35.
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
Monitor XT35 features Binding post type posts and R-34C 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 Polk XT35's and Klipsch R-34C's external dimensions. Polk XT35 has external dimensions of 107.0 x 621.0 x 142.0mm ( 4-3/16 x 24-7/16 x 5-9/16inch) whereas 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) .
Klipsch R-34C is clearly the larger of the two speakers. Its body is 41mm wider, 19mm taller and 17mm deeper than Polk XT35.
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 Polk XT35 is approximately 881.8cm2 / 136.7inch2 and base area of the Klipsch R-34C is approximately 1052.6cm2 / 163.2inch2. The Monitor XT35 requires 16% less surface area than the R-34C 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 Polk XT35 weighs 6.36kg / 14lbs and the Klipsch R-34C weighs 5.91kg / 13lbs. This makes the Monitor XT35 8% heavier than the R-34C.
Here is a comparison of how Monitor XT35 and R-34C's weights compare with the average, max and min weights in Passive Center Channel class.
