Airmotiv B2+ features a 25×32 mm" folded ribbon Tweeter and 1 x 6.25" woven fiber cone Woofer with a Crossover frequency at 2000Hz. On the other hand, the Airmotiv XB2 features a 25×32 mm" folded ribbon Tweeter and 1 x 6" woven fiber cone Woofer with a Crossover frequency at 2600Hz.
Frequency Response
Airmotiv B2+ has a frequency range of 40-28k Hz whereas Airmotiv XB2 has a frequency range of 55 Hz – 27 kHz. With a minimum frequency of 40Hz, the Airmotiv B2+ 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.

High Frequency
Bookshelf 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
Airmotiv B2+ and Airmotiv XB2 have the same Impedance of 4 ohms and their sensitivity is also same at 86 dB.
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 B2+ and the Airmotiv B2+ 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 B2+ and Airmotiv XB2 has the same power range of Up to 125 watts.
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 B2+ and Airmotiv XB2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Emotiva Airmotiv B2+'s Binding post terminals allows Bi-amping or bi-wiring
Emotiva Airmotiv XB2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Airmotiv B2+ and Airmotiv XB2 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 B2+'s and Emotiva Airmotiv XB2's external dimensions. Emotiva Airmotiv B2+ has external dimensions of 324.0 x 216.0 x 293.0mm ( 12-3/4-inch x 8-1/2-inch x 11-1/2-inch) whereas Emotiva Airmotiv XB2 has external dimensions of 325 x 216 x 292 mm ( 12.8” x 8.5” x 11.5”) .
Below you can see the front view size comparison of Emotiva Airmotiv B2+ and Emotiva Airmotiv XB2 in scale.

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 B2+ is approximately 632.9cm2 / 98.1inch2 and base area of the Emotiva Airmotiv XB2 is approximately 630.7cm2 / 97.8inch2. The Airmotiv B2+ requires 0% more surface area than the Airmotiv XB2 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Emotiva Airmotiv B2+ weighs 7.10kg / 15.6lbs and the Emotiva Airmotiv XB2 weighs 8.16kg / 18lbs. This makes the Airmotiv XB2 15% heavier than the Airmotiv B2+.
Here is a comparison of how Airmotiv B2+ and Airmotiv XB2's weights compare with the average, max and min weights in Passive Bookshelf class.
