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
RP-500M II and RP-500C II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-500M II sensitivity is rated at 92 dB and the RP-500C II's is at 96 dB. This 4 dB difference makes the Klipsch RP-500C II a more sensitive speaker compared to Klipsch RP-500M II, 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.
RP-500M II can handle a max power of 100 watts RMS from the amp the whereas RP-500M II has a max power handling value of 75 watts RMS , 25 watts less than the RP-500C II.
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
RP-500M II features Binding post type posts and RP-500C II has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-500M II and RP-500C II have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Klipsch RP-500M II's and Klipsch RP-500C II's external dimensions. 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) 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 RP-500C II is 168mm shorter and 1mm less deeper than Klipsch RP-500M II but it is also 319mm wider.
Below you can see the front view size comparison of Klipsch RP-500M II and Klipsch RP-500C II in scale.
