RP-404C II features a 1" titanium Tractrix Horn Tweeter and 4 x 4" Cerametallic cone Woofer with a Crossover frequency at 1900 Hz. On the other hand, the RP-500M II features a 1" titanium Hybrid Tractrix Horn Tweeter and 1 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1530 Hz.
Frequency Response
RP-404C II has a frequency range of 87-25k Hz whereas RP-500M II has a frequency range of 50-25k Hz. With a minimum frequency of 50Hz, the RP-500M II can go significantly deeper on the low side and provide stronger bass compared to the RP-404C II's min frequency of 87Hz.
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-404C II and RP-500M II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-404C II sensitivity is rated at 94 dB and the RP-500M II's is at 92 dB. This 2 dB difference makes the Klipsch RP-404C II a more sensitive speaker compared to Klipsch RP-500M II, 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.
RP-404C II can handle a max power of 125 watts RMS, whereas RP-500M II has a max power handling value of 75 watts RMS, 50 watts less than the RP-404C II.
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
RP-404C II features Binding post type posts and RP-500M 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 RP-404C II's and Klipsch RP-500M II's external dimensions. Klipsch RP-404C II has external dimensions of 147.0 x 683.0 x 166.0mm (5-3/4 x 26-7/8 x 6-1/2inch) whereas Klipsch RP-500M II has external dimensions of 345.0 x 175.0 x 270.0mm (13-9/16 x 6-7/8 x 10-5/8inch).
Klipsch RP-404C II is 198mm shorter and 104mm less deeper than Klipsch RP-500M II but it is also 508mm wider.
Below you can see the front view size comparison of Klipsch RP-404C II and Klipsch RP-500M II in scale.
