RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz. On the other hand, the R500 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 5.25" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2500Hz.
Frequency Response
RP-8000F II has a frequency range of 32-25k Hz whereas R500 has a frequency range of 49-38k Hz. With a minimum frequency of 32Hz, the RP-8000F II can go significantly deeper on the low side and provide stronger bass compared to the R500's min frequency of 49Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

High Frequency
Floor-standing Speakers
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-8000F II and R500 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-8000F II sensitivity is rated at 98 dB and the R500's is at 87 dB. This 11 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Polk R500, 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-8000F II can handle a max power of 200 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS , 50 watts less than the R500.
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. R500 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-8000F II and R500 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-8000F II's and Polk R500's external dimensions. Klipsch RP-8000F II has external dimensions of 1097.0 x 277.0 x 447.0mm ( 43-3/16 x 10-7/8 x 17-9/16inch) whereas Polk R500 has external dimensions of 1044.5 x 255.4 x 348.8mm ( 41.1 x 10.1 x 13.7inch) .
Klipsch RP-8000F II is clearly the larger of the two speakers. Its body is 21.6mm wider, 52.5mm taller and 98.2mm deeper than Polk R500.
Below you can see the front view size comparison of Klipsch RP-8000F II and Polk R500 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 RP-8000F II is approximately 1238.2cm2 / 191.9inch2 and base area of the Polk R500 is approximately 890.8cm2 / 138.1inch2. The RP-8000F II requires 39% more surface area than the R500 which gives it a small disadvantage on placement in tight spaces.
