What size room are the Polk ES55 and Klipsch RP-6000F speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Polk ES55 and Klipsch RP-6000F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

ES55 features a 1" Terylene High-Res Soft-Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer .
Frequency Response
ES55 has a frequency range of 34-40k Hz whereas RP-6000F has a frequency range of 34-25k Hz.
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

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
ES55 and RP-6000F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES55 sensitivity is rated at 89 dB and the RP-6000F's is at 97 dB. This 8 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to Polk ES55, 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.
ES55 can handle a max power of 200 watts RMS from the amp the whereas RP-6000F has a max power handling value of 125 watts RMS, 75 watts less than the ES55.
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 ES55 and RP-6000F 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
ES55 has a bottom firing port whereas RP-6000F has a rear firing ports. Polk ES55's bottom-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 Polk ES55's and Klipsch RP-6000F's external dimensions. Polk ES55 has external dimensions of 1056.0 x 216.0 x 315.0mm ( 41-9/16 x 8-1/2 x 12-3/8inch) whereas Klipsch RP-6000F has external dimensions of 1010.0 x 237.0 x 432.0mm ( 39-3/4 x 9-5/16 x 17inch) .
Polk ES55 is 21mm narrower and 117mm less deeper than Klipsch RP-6000F but it is also 46mm taller.
Below you can see the front view size comparison of Polk ES55 and Klipsch RP-6000F 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 Polk ES55 is approximately 680.4cm2 / 105.5inch2 and base area of the Klipsch RP-6000F is approximately 1023.8cm2 / 158.7inch2. The ES55 requires 34% less surface area than the RP-6000F 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 Polk ES55 weighs 20.00kg / 44lbs and the Klipsch RP-6000F weighs 22.27kg / 49lbs. This makes the RP-6000F 11% heavier than the ES55.
Here is a comparison of how ES55 and RP-6000F's weights compare with the average, max and min weights in Passive Floor-standing class.
