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. On the other hand, the Chora Center features a 1" TNF aluminum/magnesium inverted dome Tweeter and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 2100Hz.
Frequency Response
RP-504C II has a frequency range of 50-25k Hz whereas Chora Center has a frequency range of 59-28k 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 Chora Center's min frequency of 59Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
RP-504C II and Chora Center have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-504C II sensitivity is rated at 96 dB and the Chora Center's is at 91 dB. This 5 dB difference makes the Klipsch RP-504C II a more sensitive speaker compared to Focal Chora Center, hence will play louder with the same amount of watts.
Sensitivity
Center Channel Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Chora Center can handle a max power of 200 watts RMS, whereas RP-504C II has a max power handling value of 150 watts RMS, 50 watts less than the Chora Center.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
RP-504C II features Binding post type posts and Chora Center has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 RP-504C II's and Focal Chora Center's external dimensions. 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) whereas Focal Chora Center has external dimensions of 212.0 x 531.0 x 272.0mm (8-5/16 x 20-7/8 x 10-11/16inch).
Focal Chora Center is 287mm narrower and 113mm less deeper than Klipsch RP-504C II but it is also 35mm 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 Klipsch RP-504C II is approximately 3149.3cm2 / 488.1inch2 and base area of the Focal Chora Center is approximately 1444.3cm2 / 223.9inch2. The RP-504C II requires 118% more surface area than the Chora Center 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 RP-504C II weighs 16.50kg / 36.3lbs and the Focal Chora Center weighs 8.91kg / 19.6lbs. This makes the RP-504C II 85% heavier than the Chora Center.
Here is a comparison of how RP-504C II and Chora Center's weights compare with the average, max and min weights in Passive Center Channel class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | Klipsch RP-504C II digs deeper - 50Hz against 59Hz. A subwoofer would even that out. |
| Amplifier needs | A | Klipsch RP-504C II is more sensitive (96dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | B | Focal Chora Center takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Focal Chora Center is easier to place; Klipsch RP-504C II is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. Klipsch RP-504C II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($799 vs $789 a pair). |
A Klipsch RP-504C II B Focal Chora Center
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Klipsch RP-504C II has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 59Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Klipsch RP-504C II has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Focal Chora Center is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
