What size room are the Klipsch R-52C and Klipsch RP-500C speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

R-52C features a 1" aluminum Tractrix horn Tweeter and 2 x 5.25" copper spun IMG Woofer. On the other hand, the RP-500C features a 1" titanium Tractrix horn Tweeter and 2 x 5.25" Cerametallic cone Woofer.
Frequency Response
R-52C has a frequency range of 89-21k Hz whereas RP-500C has a frequency range of 60-25k Hz. With a minimum frequency of 60Hz, the RP-500C can go significantly deeper on the low side and provide stronger bass compared to the R-52C's min frequency of 89Hz.
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
R-52C and RP-500C have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-52C sensitivity is rated at 95 dB and the RP-500C's is at 96 dB. This 1 dB difference makes the Klipsch RP-500C a more sensitive speaker compared to Klipsch R-52C, hence will play louder with the same amount of watts.
Sensitivity

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.
R-52C and RP-500C have the same power range of up to 100 watts.
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.
Which plays louder on your 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
R-52C features Binding post type posts and RP-500C 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 R-52C's and Klipsch RP-500C's external dimensions. Klipsch R-52C has external dimensions of 180.0 x 478.0 x 196.0mm (7-1/16 x 18-13/16 x 7-11/16inch) whereas Klipsch RP-500C has external dimensions of 175.0 x 472.0 x 254.0mm (6-7/8 x 18-9/16 x 10inch).
Klipsch RP-500C is 6mm narrower and 5mm shorter than Klipsch R-52C but it is also 58mm deeper.
Below you can see the front view size comparison of Klipsch R-52C and Klipsch RP-500C in scale.

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-52C is approximately 936.9cm2 / 145.2inch2 and base area of the Klipsch RP-500C is approximately 1198.9cm2 / 185.8inch2. The R-52C requires 22% less surface area than the RP-500C 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 Klipsch R-52C weighs 3.18kg / 7lbs and the Klipsch RP-500C weighs 8.18kg / 18lbs. This makes the RP-500C 157% heavier than the R-52C.
Here is a comparison of how R-52C and RP-500C's weights compare with the average, max and min weights in Passive Center Channel class.

Both are Klipsch, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass | B | Klipsch RP-500C digs deeper - 60Hz against 89Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (95dB vs 96dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (100W vs 100W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Cabinet | depends | Sealed vs Ported. 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-500C sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($349 vs $379 a pair). |
A Klipsch R-52C B Klipsch RP-500C
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-500C 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 89Hz anyway, so judge these on the other rows instead.
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.
