R-50C features a 1" LTS (Linear Travel Suspension) titanium diaphragm Tractrix Horn Tweeter and 2 x 5.25" spun-copper TCP Woofer with a Crossover frequency at 1650 Hz. On the other hand, the RP-500C II features a 1" titanium Tractrix Horn Tweeter and 2 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz.
Frequency Response
R-50C has a frequency range of 90-21k Hz whereas RP-500C II has a frequency range of 60-25k Hz. With a minimum frequency of 60Hz, the RP-500C II can go significantly deeper on the low side and provide stronger bass compared to the R-50C's min frequency of 90Hz.
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-50C and RP-500C II have the same Impedance of 8 ohms and their sensitivity is also same at 96 dB.
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-50C and RP-500C II 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.

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-50C features Binding post type posts and RP-500C II 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-50C's and Klipsch RP-500C II's external dimensions. Klipsch R-50C has external dimensions of 180.0 x 478.0 x 212.0mm (7-1/16inch x 18-13/16inch x 8-5/16inch) whereas Klipsch RP-500C II has external dimensions of 177.0 x 494.0 x 269.0mm (6-15/16 x 19-7/16 x 10-9/16inch).
Klipsch R-50C is 16mm narrower and 57mm less deeper than Klipsch RP-500C II but it is also 3mm taller.
Below you can see the front view size comparison of Klipsch R-50C and Klipsch RP-500C II 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-50C is approximately 1013.4cm2 / 157.1inch2 and base area of the Klipsch RP-500C II is approximately 1328.9cm2 / 206.0inch2. The R-50C requires 24% less surface area than the RP-500C 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 Klipsch R-50C weighs 6.40kg / 14.1lbs and the Klipsch RP-500C II weighs 8.20kg / 18lbs. This makes the RP-500C II 28% heavier than the R-50C.
Here is a comparison of how R-50C and RP-500C II's weights compare with the average, max and min weights in Passive Center Channel class.

A generation apart: Klipsch RP-500C II is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass |
B |
Klipsch RP-500C II digs deeper - 60Hz against 90Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (96dB vs 96dB) - both want much the same power. |
| Headroom |
evenly matched |
Similar power handling (100W vs 100W). |
| Size |
depends |
Klipsch R-50C is easier to place; Klipsch RP-500C II is bigger, which usually goes with fuller bass. Your room decides. |
| 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 II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price |
A |
Klipsch R-50C is cheaper - $379 against $499, about 24% less. |
A Klipsch R-50C
B Klipsch RP-500C II
depends neither is better in the abstract - it turns on your room, placement 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?
The usual trade-off: Klipsch RP-500C II measures better, Klipsch R-50C costs about 24% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 90Hz anyway, which makes the cheaper Klipsch R-50C much easier to justify.
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.
