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-504C II can handle a max power of 150 watts RMS from the amp the whereas RP-6000F II has a max power handling value of 125 watts RMS, 25 watts less than the RP-504C 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-6000F II features Binding post posts which make bi-amping or bi-wiring possible. RP-504C II has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-504C II and RP-6000F 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-504C II's and Klipsch RP-6000F II's external dimensions. Klipsch RP-504C II has external dimensions of 177.0 x 818.0 x 385.0mm ( 6-15/16 x 32-3/16 x 15-1/8inch) whereas Klipsch RP-6000F II has external dimensions of 1007.0 x 237.0 x 431.0mm ( 39-5/8 x 9-5/16 x 16-15/16inch) .
Klipsch RP-504C II is 830mm shorter and 46mm less deeper than Klipsch RP-6000F II but it is also 581mm wider.
