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-404C II and RP-8000F 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-8000F II's is at 98 dB. This 4 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Klipsch RP-404C 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-404C II can handle a max power of 150 watts RMS from the amp the whereas RP-404C II has a max power handling value of 125 watts RMS , 25 watts less than the RP-8000F 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-8000F II features Binding post posts which make bi-amping or bi-wiring possible. RP-404C II has a Binding post which doesn't feature bi-amping/bi-wiring.
