Drivers
One of the fundamental differences between these two speakers is that Airmotiv C3+ is a 3-way design whereas the DALI Spektor Vokal 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 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. On the other hand, the DALI Spektor Vokal features a 1" Soft-Dome Tweeter and 2 x 4.5" Wood Fiber Woofer with a Crossover frequency at 2100Hz.
Frequency Response
Airmotiv C3+ has a frequency range of 40 Hz – 28 kHz whereas DALI Spektor Vokal has a frequency range of 66-26k Hz. With a minimum frequency of 40Hz, the Airmotiv C3+ can go significantly deeper on the low side and provide stronger bass compared to the DALI Spektor Vokal's min frequency of 66Hz.
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.

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 C3+ is a 4 ohms speaker compared to the DALI Spektor Vokal 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 C3+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv C3+ sensitivity is rated at 92 dB and the DALI Spektor Vokal's is rated at 87 dB. This 5 dB difference makes the Emotiva Airmotiv C3+ a more sensitive speaker compared to DALI Spektor Vokal, 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 C3+ can handle a max power of 200 watts RMS from the amp the whereas DALI Spektor Vokal has a max power handling value of 120 watts RMS, 80 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
Airmotiv C3+ features Binding post posts which make bi-amping or bi-wiring possible. DALI Spektor Vokal has a Binding post which doesn't feature bi-amping/bi-wiring.
Emotiva Airmotiv C3+'s Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Airmotiv C3+ and DALI Spektor Vokal 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 C3+'s and DALI Spektor Vokal's external dimensions. Emotiva Airmotiv C3+ has external dimensions of 220.0 x 1391.0 x 312.0mm ( 8-5/8-inch x 54-3/4-inch x 12-1/4-inch) whereas DALI Spektor Vokal has external dimensions of 152.0 x 435.0 x 204.0mm ( 6 x 17.1 x 8inch) .
Emotiva Airmotiv C3+ is clearly the larger of the two speakers. Its body is 956mm wider, 68mm taller and 108mm deeper than DALI Spektor Vokal.
Below you can see the front view size comparison of Emotiva Airmotiv C3+ and DALI Spektor Vokal 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 C3+ is approximately 4339.9cm2 / 672.7inch2 and base area of the DALI Spektor Vokal is approximately 887.4cm2 / 137.5inch2. The Airmotiv C3+ requires 389% more surface area than the DALI Spektor Vokal which gives it a small disadvantage on placement in tight spaces.
