RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer . On the other hand, the RTi A5 features a 1" Tweeter and 2 x 6.5" Polymer composite Woofer .
Frequency Response
RP-6000F has a frequency range of 34-25k Hz whereas RTi A5 has a frequency range of 40-26k Hz. With a minimum frequency of 34Hz, the RP-6000F can go significantly deeper on the low side and provide stronger bass compared to the RTi A5's min frequency of 40Hz.
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.

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-6000F and RTi A5 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-6000F sensitivity is rated at 97 dB and the RTi A5's is at 90 dB. This 7 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to Polk RTi A5, 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-6000F can handle a max power of 250 watts RMS from the amp the whereas RP-6000F has a max power handling value of 125 watts RMS , 125 watts less than the RTi A5.
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
Both RP-6000F and RTi A5 features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-6000F's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
RP-6000F has a rear firing port whereas RTi A5 has a front firing ports. Polk RTi A5's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-6000F with its rear-firing port.
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-6000F's and Polk RTi A5's external dimensions. Klipsch RP-6000F has external dimensions of 1010.0 x 237.0 x 432.0mm ( 39-3/4 x 9-5/16 x 17inch) whereas Polk RTi A5 has external dimensions of 1007.0 x 269.0 x 404.0mm ( 39-5/8 x 10-9/16 x 15-7/8inch) .
Polk RTi A5 is 3mm shorter and 28mm less deeper than Klipsch RP-6000F but it is also 32mm wider.
Below you can see the front view size comparison of Klipsch RP-6000F and Polk RTi A5 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-6000F is approximately 1023.8cm2 / 158.7inch2 and base area of the Polk RTi A5 is approximately 1086.8cm2 / 168.5inch2. The RP-6000F requires 6% less surface area than the RTi A5 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Klipsch RP-6000F weighs 22.27kg / 49lbs and the Polk RTi A5 weighs 18.18kg / 40lbs. This makes the RP-6000F 22% heavier than the RTi A5.
Here is a comparison of how RP-6000F and RTi A5's weights compare with the average, max and min weights in Passive Floor-standing class.
