Kendall 2C features a 1" Hard-Dome Tweeter , a 3" Midrange and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 800-2500 HZ. On the other hand, the Airmotiv C3+ features a 25×32 mm" folded ribbon Tweeter , a 5.25" Midrange and 4 x 6.5" woven fiber cone Woofer with a Crossover frequency at 350 Hz and 2800Hz.
Frequency Response
Kendall 2C has a frequency range of 50-20k Hz whereas Airmotiv C3+ has a frequency range of 40 Hz – 28 kHz. With a minimum frequency of 40Hz, the Airmotiv C3+ can go significantly deeper on the low side and provide stronger bass compared to the Kendall 2C's min frequency of 50Hz.
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.

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
Kendall 2C is a 8 ohms speaker compared to the Airmotiv C3+ 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 C3+ can provide this impedance level.
These two speakers also have different sensitivity levels. Kendall 2C sensitivity is rated at 87 dB and the Airmotiv C3+'s is rated at 92 dB. This 5 dB difference makes the Emotiva Airmotiv C3+ a more sensitive speaker compared to KLH Kendall 2C, 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.
Kendall 2C can handle a max power of 250 watts RMS from the amp the whereas Airmotiv C3+ has a max power handling value of 200 watts RMS, 50 watts less than the Kendall 2C.
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
Both Kendall 2C and Airmotiv C3+ features dual binding post speaker terminals for bi-amping or bi-wiring.
KLH Kendall 2C's 5-Way post terminals allows Bi-amping or bi-wiring
Emotiva Airmotiv C3+'s Binding post terminals allows Bi-amping or 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 KLH Kendall 2C's and Emotiva Airmotiv C3+'s external dimensions. KLH Kendall 2C has external dimensions of 216.0 x 489.0 x 235.0mm ( 8-1/2inch x 19-1/4inch x 9-1/4inch ) whereas Emotiva Airmotiv C3+ has external dimensions of 220.0 x 1391.0 x 312.0mm ( 8-5/8-inch x 54-3/4-inch x 12-1/4-inch) .
Emotiva Airmotiv C3+ is clearly the larger of the two speakers. Its body is 902mm wider, 4mm taller and 77mm deeper than KLH Kendall 2C.
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 KLH Kendall 2C is approximately 1149.2cm2 / 178.1inch2 and base area of the Emotiva Airmotiv C3+ is approximately 4339.9cm2 / 672.7inch2. The Kendall 2C requires 74% less surface area than the Airmotiv C3+ which gives it a small advantage on placement in tight spaces.
