History
What size room are the Klipsch RP-6000F and Klipsch RP-450C 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 Klipsch RP-6000F and Klipsch RP-450C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer . On the other hand, the RP-450C features a 1" titanium Tractrix horn Tweeter and 4 x 5.25" Cerametallic cone Woofer .
Frequency Response
RP-6000F has a frequency range of 34-25k Hz whereas RP-450C has a frequency range of 58-25k 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 RP-450C's min frequency of 58Hz.
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 RP-450C have the same Impedance of 8 ohms and their sensitivity is also same at 97 dB.

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 150 watts RMS from the amp the whereas RP-6000F has a max power handling value of 125 watts RMS , 25 watts less than the RP-450C.
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 features Post posts which make bi-amping or bi-wiring possible. RP-450C has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-6000F and RP-450C 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-6000F's and Klipsch RP-450C'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 Klipsch RP-450C has external dimensions of 174.0 x 791.0 x 370.0mm ( 6-13/16 x 31-1/8 x 14-9/16inch) .
Klipsch RP-450C is 836mm shorter and 62mm less deeper than Klipsch RP-6000F but it is also 554mm wider.
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 Klipsch RP-450C is approximately 2926.7cm2 / 453.6inch2. The RP-6000F requires 65% less surface area than the RP-450C which gives it a small advantage on placement in tight spaces.
