History
What size room are the Klipsch RP-6000F and Klipsch RP-400M 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.)

RP-6000F features a 1" Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer. On the other hand, the RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
RP-6000F has a frequency range of 34-25k Hz whereas RP-400M has a frequency range of 52-25k 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-400M's min frequency of 52Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
RP-6000F and RP-400M 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 RP-400M's is at 93 dB. This 4 dB difference makes the Klipsch RP-6000F a more sensitive speaker compared to Klipsch RP-400M, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
RP-6000F can handle a max power of 125 watts RMS, whereas RP-400M has a max power handling value of 50 watts RMS, 75 watts less than the RP-6000F.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
RP-6000F features Post posts which make bi-amping or bi-wiring possible. RP-400M has a Single binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-6000F and RP-400M 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
The size of a speaker can sometimes be 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-400M'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-400M has external dimensions of 298.0 x 144.0 x 191.0mm (11.7 x 5.6 x 7.5inch).
Klipsch RP-6000F is clearly the larger of the two speakers. Its body is 93mm wider, 712mm taller and 241mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Klipsch RP-6000F and Klipsch RP-400M 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 Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2. The RP-6000F requires 272% more surface area than the RP-400M which gives it a small disadvantage on placement in tight spaces.
