What size room are the Klipsch R-52C and Klipsch R-620F 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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both R-52C and R-620F are 2-way speakers.

R-52C features a 1" aluminum Tractrix horn Tweeter and 2 x 5.25" copper spun IMG Woofer. On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
R-52C has a frequency range of 89-21k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go significantly deeper on the low side and provide stronger bass compared to the R-52C's min frequency of 89Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
R-52C and R-620F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-52C sensitivity is rated at 95 dB and the R-620F's is at 96 dB. This 1 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Klipsch R-52C, 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.
R-52C and R-620F have the same power range of up to 100 watts.
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
R-52C features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

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 R-52C's and Klipsch R-620F's external dimensions. Klipsch R-52C has external dimensions of 180.0 x 478.0 x 196.0mm (7-1/16 x 18-13/16 x 7-11/16inch) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm (40-3/16 x 9-3/8 x 14-1/2inch).
Klipsch R-52C is 841mm shorter and 173mm less deeper than Klipsch R-620F but it is also 239mm wider.
Below you can see the front view size comparison of Klipsch R-52C and Klipsch R-620F 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 R-52C is approximately 936.9cm2 / 145.2inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The R-52C requires 6% more surface area than the R-620F which gives it a small disadvantage on placement in tight spaces.
