What size room are the Emotiva Airmotiv C2+ and Dynaudio Evoke 25C 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.)
In the following sections, we will get into more detail in order to better understand how the Emotiva Airmotiv C2+ and Dynaudio Evoke 25C 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 C2+ is a 3-way design whereas the Evoke 25C is a 2-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 C2+ features a 25×32 mm" folded ribbon Tweeter , a 3" Midrange and 2 x 6.5" woven fiber cone Woofer with a Crossover frequency at 350 Hz and 3200Hz. On the other hand, the Evoke 25C features a 1.1" Cerotar coated silk soft-dome Tweeter and 2 x 5.5" Esotec+ MSP Woofer with a Crossover frequency at 1200 and 2300Hz.
Frequency Response
Airmotiv C2+ has a frequency range of 45 Hz – 28 kHz whereas Evoke 25C has a frequency range of 50-23k Hz. With a minimum frequency of 45Hz, the Airmotiv C2+ can go significantly deeper on the low side and provide stronger bass compared to the Evoke 25C's min frequency of 50Hz.
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 Center Channel class in our database.

Center Channel Speakers
High Frequency
Center Channel 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 C2+ is a 4 ohms speaker compared to the Evoke 25C which has a nominal impedance of 6 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Airmotiv C2+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv C2+ sensitivity is rated at 92 dB and the Evoke 25C's is rated at 88 dB. This 4 dB difference makes the Emotiva Airmotiv C2+ a more sensitive speaker compared to Dynaudio Evoke 25C, hence will play louder with the same amount of watts.

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 C2+ can handle a max power of 200 watts RMS from the amp the whereas Airmotiv C2+ has a max power handling value of 150 watts RMS , 50 watts less than the Evoke 25C.
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
Airmotiv C2+ features Binding post posts which make bi-amping or bi-wiring possible. Evoke 25C has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Airmotiv C2+ and Evoke 25C 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 C2+'s and Dynaudio Evoke 25C's external dimensions. Emotiva Airmotiv C2+ has external dimensions of 220.0 x 812.0 x 267.0mm ( 8-5/8 x 31-15/16 x 10-1/2inch) whereas Dynaudio Evoke 25C has external dimensions of 183.0 x 602.0 x 281.0mm ( 7-3/16 x 23-11/16 x 11-1/16inch) .
Dynaudio Evoke 25C is 210mm narrower and 37mm shorter than Emotiva Airmotiv C2+ but it is also 14mm 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 C2+ is approximately 2168.0cm2 / 336.0inch2 and base area of the Dynaudio Evoke 25C is approximately 1691.6cm2 / 262.2inch2. The Airmotiv C2+ requires 28% more surface area than the Evoke 25C which gives it a small disadvantage on placement in tight spaces.
