Drivers
One of the fundamental differences between these two speakers is that Airmotiv XB2 is a 2-way design whereas the Airmotiv XC2 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.

Airmotiv XB2 features a 25×32 mm" folded ribbon Tweeter and 1 x 6" woven fiber cone Woofer with a Crossover frequency at 2600Hz. On the other hand, the Airmotiv XC2 features a 25×32 mm" folded ribbon Tweeter , a 5.25" Midrange and 2 x 6" woven fiber cone Woofer with a Crossover frequency at 600 Hz, 3.1 kHz.
Frequency Response
Airmotiv XB2 has a frequency range of 55 Hz – 27 kHz whereas Airmotiv XC2 has a frequency range of 40 Hz – 27 kHz. With a minimum frequency of 40Hz, the Airmotiv XC2 can go significantly deeper on the low side and provide stronger bass compared to the Airmotiv XB2's min frequency of 55Hz.
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 Bookshelf 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 XB2 and Airmotiv XC2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Airmotiv XB2 sensitivity is rated at 86 dB and the Airmotiv XC2's is at 89 dB. This 3 dB difference makes the Emotiva Airmotiv XC2 a more sensitive speaker compared to Emotiva Airmotiv XB2, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Airmotiv XB2 and the Airmotiv XB2 can provide this impedance level.

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 XB2 can handle a max power of 150 watts RMS from the amp the whereas Airmotiv XB2 has a max power handling value of 125 watts RMS , 25 watts less than the Airmotiv XC2.
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 Airmotiv XB2 and Airmotiv XC2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Emotiva Airmotiv XB2's Binding post terminals allows Bi-amping or bi-wiring
Emotiva Airmotiv XC2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Airmotiv XB2 and Airmotiv XC2 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 Emotiva Airmotiv XB2's and Emotiva Airmotiv XC2's external dimensions. Emotiva Airmotiv XB2 has external dimensions of 325 x 216 x 292 mm ( 12.8” x 8.5” x 11.5”) whereas Emotiva Airmotiv XC2 has external dimensions of 216 x 800 x 260 mm ( 8.5” x 31.5” x 10.25”) .
Emotiva Airmotiv XC2 is 109mm shorter and 32mm less deeper than Emotiva Airmotiv XB2 but it is also 584mm wider.
