What size room are the Klipsch RP-4000F and Klipsch RP-500M 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-4000F and Klipsch RP-500M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

RP-4000F features a 1" Tractrix Horn Tweeter and 2 x 4" Cerametallic Woofer . On the other hand, the RP-500M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
RP-4000F has a frequency range of 37-25k Hz whereas RP-500M has a frequency range of 48-25k Hz. With a minimum frequency of 37Hz, the RP-4000F can go significantly deeper on the low side and provide stronger bass compared to the RP-500M's min frequency of 48Hz.
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
RP-4000F and RP-500M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-4000F sensitivity is rated at 95 dB and the RP-500M's is at 93 dB. This 2 dB difference makes the Klipsch RP-4000F a more sensitive speaker compared to Klipsch RP-500M, 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-4000F and RP-500M has the same power range of up to 75 watts.
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-4000F features Binding post posts which make bi-amping or bi-wiring possible. RP-500M has a Single binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-4000F and RP-500M 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-4000F's and Klipsch RP-500M's external dimensions. Klipsch RP-4000F has external dimensions of 870.0 x 188.0 x 289.0mm ( 34-1/4 x 7-3/8 x 11-3/8inch) whereas Klipsch RP-500M has external dimensions of 343.0 x 173.0 x 241.0mm ( 13.5 x 6.8 x 9.4inch) .
Klipsch RP-4000F is clearly the larger of the two speakers. Its body is 15mm wider, 527mm taller and 48mm deeper than Klipsch RP-500M.
Below you can see the front view size comparison of Klipsch RP-4000F and Klipsch RP-500M 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-4000F is approximately 543.3cm2 / 84.2inch2 and base area of the Klipsch RP-500M is approximately 416.9cm2 / 64.6inch2. The RP-4000F requires 30% more surface area than the RP-500M which gives it a small disadvantage on placement in tight spaces.
