Theva Center features a 1" TNF Al/Mg inverted dome Tweeter and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 2100 Hz. On the other hand, the RP-504C II features a 1" titanium Tractrix Horn Tweeter and 4 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1950 Hz.
Frequency Response
Theva Center has a frequency range of 59-28kHz whereas RP-504C II has a frequency range of 50-25k Hz. With a minimum frequency of 50Hz, the RP-504C II can go significantly deeper on the low side and provide stronger bass compared to the Theva Center's min frequency of 59Hz.
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
Theva Center and RP-504C II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva Center sensitivity is rated at 91 dB and the RP-504C II's is at 96 dB. This 5 dB difference makes the Klipsch RP-504C II a more sensitive speaker compared to Focal Theva Center, 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.
Theva Center can handle a max power of 200 watts RMS from the amp the whereas RP-504C II has a max power handling value of 150 watts RMS, 50 watts less than the Theva Center.
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
Theva Center features Binding post posts which make bi-amping or bi-wiring possible. RP-504C II has a Binding post which doesn't 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 Focal Theva Center's and Klipsch RP-504C II's external dimensions. Focal Theva Center has external dimensions of 210.0 x 531.0 x 254.0mm ( 81/4 x 207/8 x 10) whereas Klipsch RP-504C II has external dimensions of 177.0 x 818.0 x 385.0mm ( 6-15/16 x 32-3/16 x 15-1/8inch) .
Focal Theva Center is 287mm narrower and 131mm less deeper than Klipsch RP-504C II but it is also 33mm taller.
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 Focal Theva Center is approximately 1348.7cm2 / 209.0inch2 and base area of the Klipsch RP-504C II is approximately 3149.3cm2 / 488.1inch2. The Theva Center requires 57% less surface area than the RP-504C II 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 Focal Theva Center weighs 10.00kg / 22lbs and the Klipsch RP-504C II weighs 16.50kg / 36.3lbs. This makes the RP-504C II 65% heavier than the Theva Center.
Here is a comparison of how Theva Center and RP-504C II's weights compare with the average, max and min weights in Passive Center Channel class.
