In this review, we will be comparing R-30C and Airmotiv C1+, two Passive Center Channel speakers from Klipsch and Emotiva. Let's have a brief look at the main features
of Klipsch R-30C and Emotiva Airmotiv C1+ first before getting into our more
detailed comparison.
What size room are the Klipsch R-30C and Emotiva Airmotiv C1+ 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 Emotiva Airmotiv C1+ compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that R-30C is a 2-way design whereas the Airmotiv C1+ is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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 Airmotiv C1+ features a 25×32 mm" folded ribbon Tweeter , a 3" Midrange and 2 x 5.25" woven fiber cone Woofer with a Crossover frequency at 550 Hz and 2600Hz.
Frequency Response
R-30C has a frequency range of 78-21k Hz whereas Airmotiv C1+ has a frequency range of 50 Hz – 28 kHz. With a minimum frequency of 50Hz, the Airmotiv C1+ 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

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 Airmotiv C1+ 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 Airmotiv C1+ can provide this impedance level.
These two speakers also have different sensitivity levels. R-30C sensitivity is rated at 96 dB and the Airmotiv C1+'s is rated at 89 dB. This 7 dB difference makes the Klipsch R-30C a more sensitive speaker compared to Emotiva Airmotiv C1+, hence will play louder with the same amount of watts.
Sensitivity

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 120 watts RMS from the amp the whereas R-30C has a max power handling value of 100 watts RMS , 20 watts less than the Airmotiv C1+.
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
Airmotiv C1+ 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.
Cabinet Type and Port Position
Both R-30C and Airmotiv C1+ 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 Emotiva Airmotiv C1+'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 Emotiva Airmotiv C1+ has external dimensions of 197.0 x 521.0 x 210.0mm ( 7-3/4 x 20-1/2 x 8-1/4inch) .
Klipsch R-30C is 71mm shorter and 36mm less deeper than Emotiva Airmotiv C1+ but it is also 141mm 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 Emotiva Airmotiv C1+ is approximately 1094.1cm2 / 169.6inch2. The R-30C requires 5% more surface area than the Airmotiv C1+ which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Klipsch R-30C weighs 5.00kg / 11lbs and the Emotiva Airmotiv C1+ weighs 8.45kg / 18.6lbs. This makes the Airmotiv C1+ 69% heavier than the R-30C.
Here is a comparison of how R-30C and Airmotiv C1+'s weights compare with the average, max and min weights in Passive Center Channel class.
