Drivers
One of the fundamental differences between these two speakers is that Airmotiv C2+ is a 3-way design whereas the Chora Center is a 2-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.

Airmotiv C2+ features a 25×32 mm" folded ribbon Tweeter , a 3" Midrange and 2 x 6.5" woven fiber cone Woofer with a Crossover frequency at 350 Hz and 3200Hz. On the other hand, the Chora Center features a 1" TNF aluminum/magnesium inverted dome Tweeter and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 2100Hz.
Frequency Response
Airmotiv C2+ has a frequency range of 45 Hz – 28 kHz whereas Chora Center has a frequency range of 59-28k Hz. With a minimum frequency of 45Hz, the Airmotiv C2+ can go significantly deeper on the low side and provide stronger bass compared to the Chora Center's min frequency of 59Hz.
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.

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
Airmotiv C2+ is a 4 ohms speaker compared to the Chora Center which has a nominal impedance of 8 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 C2+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv C2+ sensitivity is rated at 92 dB and the Chora Center's is rated at 91 dB. This 1 dB difference makes the Emotiva Airmotiv C2+ a more sensitive speaker compared to Focal Chora Center, 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.
Airmotiv C2+ can handle a max power of 200 watts RMS from the amp the whereas Airmotiv C2+ has a max power handling value of 150 watts RMS , 50 watts less than the Chora Center.
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 C2+ features Binding post posts which make bi-amping or bi-wiring possible. Chora Center has a Binding post which doesn't feature bi-amping/bi-wiring.

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 Emotiva Airmotiv C2+'s and Focal Chora Center's external dimensions. Emotiva Airmotiv C2+ has external dimensions of 220.0 x 812.0 x 267.0mm ( 8-5/8 x 31-15/16 x 10-1/2inch) whereas Focal Chora Center has external dimensions of 212.0 x 531.0 x 272.0mm ( 8-5/16 x 20-7/8 x 10-11/16inch) .
Focal Chora Center is 281mm narrower and 8mm shorter than Emotiva Airmotiv C2+ but it is also 5mm deeper.
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 Emotiva Airmotiv C2+ is approximately 2168.0cm2 / 336.0inch2 and base area of the Focal Chora Center is approximately 1444.3cm2 / 223.9inch2. The Airmotiv C2+ requires 50% more surface area than the Chora Center which gives it a small disadvantage on placement in tight spaces.
