Airmotiv T-Zero+ features a 25×32 mm" folded ribbon Tweeter and 2 x 5.25" woven fiber cone Woofer with a Crossover frequency at 2500Hz. On the other hand, the 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.
Frequency Response
Airmotiv T-Zero+ has a frequency range of 48-28 kHz whereas Airmotiv B2+ has a frequency range of 40-28k Hz. 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 T-Zero+'s min frequency of 48Hz.
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 Floor-standing 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 T-Zero+ and Airmotiv B2+ have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Airmotiv T-Zero+ sensitivity is rated at 87 dB and the Airmotiv B2+'s is at 86 dB. This 1 dB difference makes the Emotiva Airmotiv T-Zero+ a more sensitive speaker compared to Emotiva Airmotiv B2+, 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 T-Zero+ and the Airmotiv T-Zero+ 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 T-Zero+ can handle a max power of 125 watts RMS from the amp the whereas Airmotiv T-Zero+ has a max power handling value of 100 watts RMS , 25 watts less than the Airmotiv B2+.
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.
Cabinet Type and Port Position
Both Airmotiv T-Zero+ and Airmotiv B2+ 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 T-Zero+'s and Emotiva Airmotiv B2+'s external dimensions. Emotiva Airmotiv T-Zero+ has external dimensions of 969.0 x 969.0 x 267.0mm ( 38-1/8 x 38-1/8 x 10-1/2inch) whereas 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) .
Emotiva Airmotiv B2+ is 753mm narrower and 645mm shorter than Emotiva Airmotiv T-Zero+ but it is also 26mm 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 T-Zero+ is approximately 2587.2cm2 / 401.0inch2 and base area of the Emotiva Airmotiv B2+ is approximately 632.9cm2 / 98.1inch2. The Airmotiv T-Zero+ requires 309% more surface area than the Airmotiv B2+ which gives it a small disadvantage on placement in tight spaces.
