What size room are the Emotiva Airmotiv B2+ and Emotiva Airmotiv C3+ 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:

Listening Environment* Emotiva Airmotiv B2+ Emotiva Airmotiv C3+
Near-field Average Poor
Small Room Good Average
Mid-size Room Average Good
Large Room Poor Average
Very Large Room Bad Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. 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.)

In the following sections, we will get into more detail in order to better understand how the Emotiva Airmotiv B2+ and Emotiva Airmotiv C3+ compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers

One of the fundamental differences between these two speakers is that Airmotiv B2+ is a 2-way design whereas the Airmotiv C3+ 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.

Tweeter 25×32 mm-inch 25×32 mm-inch
Midrange - 2 x 5.25-inch
Woofer 1 x 6.25-inch 4 x 6.5-inch

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 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

Airmotiv B2+ has a frequency range of 40-28k Hz whereas Airmotiv C3+ has a frequency range of 40 Hz – 28 kHz.

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 B2+ and Airmotiv C3+ 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 C3+'s is at 92 dB. This 6 dB difference makes the Emotiva Airmotiv C3+ 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. 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+ can handle a max power of 200 watts RMS from the amp the whereas Airmotiv B2+ has a max power handling value of 125 watts RMS , 75 watts less than the Airmotiv C3+.

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 C3+ features dual binding post speaker terminals for bi-amping or bi-wiring.

Cabinet Type and Port Position

Both Airmotiv B2+ and Airmotiv C3+ 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.
