History
What size room are the Emotiva Airmotiv B2+ and Emotiva Airmotiv T3+ speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Airmotiv B2+ is a 2-way design whereas the Airmotiv T3+ 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 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 T3+ features a 25×32 mm" folded ribbon Tweeter, a 5.25" Midrange and 3 x 8" woven fiber cone Woofer with a Crossover frequency at 350 Hz and 2800Hz.
Frequency Response
Airmotiv B2+ has a frequency range of 40-28k Hz whereas Airmotiv T3+ has a frequency range of 29 Hz – 28 kHz. With a minimum frequency of 29Hz, the Airmotiv T3+ can go significantly deeper on the low side and provide stronger bass compared to the Airmotiv B2+'s min frequency of 40Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Airmotiv B2+ and Airmotiv T3+ have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Airmotiv B2+ sensitivity is rated at 86 dB and the Airmotiv T3+'s is at 91 dB. This 5 dB difference makes the Emotiva Airmotiv T3+ 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 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Airmotiv T3+ can handle a max power of 250 watts RMS, whereas Airmotiv B2+ has a max power handling value of 125 watts RMS, 125 watts less than the Airmotiv T3+.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Airmotiv B2+ and Airmotiv T3+ 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 T3+'s Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Airmotiv B2+ and Airmotiv T3+ 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
The size of a speaker can sometimes be 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 T3+'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 T3+ has external dimensions of 1258.0 x 318.0 x 432.0mm (49-1/2-inch x 12-1/2-inch x 17-inch).
Emotiva Airmotiv T3+ is clearly the larger of the two speakers. Its body is 102mm wider, 934mm taller and 139mm deeper than Emotiva Airmotiv B2+.
Below you can see the front view size comparison of Emotiva Airmotiv B2+ and Emotiva Airmotiv T3+ 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 T3+ is approximately 1373.8cm2 / 212.9inch2. The Airmotiv B2+ requires 54% less surface area than the Airmotiv T3+ which gives it a small advantage on placement in tight spaces.
