What size room are the Klipsch R-30C and Klipsch RF-7 III 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 R-30C and Klipsch RF-7 III compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 RF-7 III features a 1.75" titanium dome Tweeter and 2 x 10" Cerametallic Woofer with a Crossover frequency at 1300Hz.
Frequency Response
R-30C has a frequency range of 78-21k Hz whereas RF-7 III has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RF-7 III 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.
Low Frequency
Center Channel Speakers
High Frequency
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 RF-7 III have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R-30C sensitivity is rated at 96 dB and the RF-7 III's is at 100 dB. This 4 dB difference makes the Klipsch RF-7 III a more sensitive speaker compared to Klipsch R-30C, 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.
R-30C can handle a max power of 250 watts RMS from the amp the whereas R-30C has a max power handling value of 100 watts RMS , 150 watts less than the RF-7 III.
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
RF-7 III features Binding post posts which make bi-amping or bi-wiring possible. R-30C has a Binding post which doesn't feature bi-amping/bi-wiring.

Klipsch RF-7 III's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both R-30C and RF-7 III 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 R-30C's and Klipsch RF-7 III'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 RF-7 III has external dimensions of 1247.0 x 355.0 x 456.0mm ( 49-1/16 x 13-15/16 x 17-15/16inch) .
Klipsch R-30C is 1121mm shorter and 282mm less deeper than Klipsch RF-7 III but it is also 307mm wider.
Below you can see the front view size comparison of Klipsch R-30C and Klipsch RF-7 III 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 RF-7 III is approximately 1618.8cm2 / 250.9inch2. The R-30C requires 29% less surface area than the RF-7 III which gives it a small advantage on placement in tight spaces.
