In this review, we will be comparing two different type of speakers by Klipsch. Klipsch Reference R-30C is a Center Channel speaker whereas the R-620F is a Floor-standing speaker.
Let's have a brief look at the main features
of Klipsch R-30C and Klipsch R-620F first before getting into our more
detailed comparison.
R-30C and R-620F are members of Klipsch's Reference (R) series of speakers. Below you can find the loudspeakers from this series.

What size room are the Klipsch R-30C 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:
In the following sections, we will get into more detail in order to better understand how the Klipsch R-30C and Klipsch R-620F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
Both R-30C and R-620F are 2-way speakers. R-30C features a 1" LTS (Linear Travel Suspension) titanium diaphragm Tractrix Horn Tweeter and 4 x 3.5" spun-copper TCP Woofer with a Crossover frequency at 1650 Hz. 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-30C has a frequency range of 78-21k 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-30C's min frequency of 78Hz.
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 Center Channel class in our database.

Center Channel Speakers
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
R-30C and R-620F have the same Impedance of 8 ohms and their sensitivity is also same at 96 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.
R-30C and R-620F has the same power range of up to 100 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
R-30C features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both R-30C and R-620F 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.
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 R-30C's and Klipsch R-620F's external dimensions. Klipsch R-30C has external dimensions of 126.0 x 662.0 x 174.0mm ( 4-15/16inch x 26-1/16inch x 6-13/16inch ) 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-30C is 895mm shorter and 195mm less deeper than Klipsch R-620F but it is also 423mm wider.
Below you can see the front view size comparison of Klipsch R-30C 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-30C is approximately 1151.9cm2 / 178.5inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The R-30C requires 31% more surface area than the R-620F which gives it a small disadvantage on placement in tight spaces.
