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 Lumina CI features a 1.15" high definition DAD Tweeter and 2 x 4.75" paper cone Woofer with a Crossover frequency at 2000 Hz.
Frequency Response
R-30C has a frequency range of 78-21k Hz whereas Lumina CI has a frequency range of 65-24k Hz. With a minimum frequency of 65Hz, the Lumina CI 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 is a 8 ohms speaker compared to the Lumina CI which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Lumina CI can provide this impedance level.
These two speakers also have different sensitivity levels. R-30C sensitivity is rated at 96 dB and the Lumina CI's is rated at 87 dB. This 9 dB difference makes the Klipsch R-30C a more sensitive speaker compared to Sonus Lumina Center I, 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.
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
Lumina CI 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.

Sonus Lumina Center I's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
R-30C has a rear firing port whereas Lumina CI has a front firing ports. Sonus Lumina Center I's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch R-30C with its rear-firing port.
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 Sonus Lumina Center I'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 Sonus Lumina Center I has external dimensions of 169.0 x 524.0 x 213.0mm ( 6.6 x 20.6 x 8.4inch) .
Klipsch R-30C is 43mm shorter and 39mm less deeper than Sonus Lumina Center I but it is also 138mm wider.

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 Sonus Lumina Center I is approximately 1116.1cm2 / 173.0inch2. The R-30C requires 3% more surface area than the Lumina CI which gives it a small disadvantage on placement in tight spaces.
