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 Silver C250 7G features a 1" gold dome C-CAM Tweeter , a 3" Midrange and 2 x 5.25" C-CAM with Rigid Surface Technology (RST) Woofer .
Frequency Response
Airmotiv C3+ has a frequency range of 40 Hz – 28 kHz whereas Silver C250 7G has a frequency range of 65-35k 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 Silver C250 7G's min frequency of 65Hz.
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.

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 Silver C250 7G which has a nominal impedance of 8 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 Silver C250 7G's is rated at 88.5 dB. This 3 dB difference makes the Emotiva Airmotiv C3+ a more sensitive speaker compared to Monitor Audio Silver C250 7G, 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.
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. Silver C250 7G has a Binding post which doesn't feature bi-amping/bi-wiring.

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 Monitor Audio Silver C250 7G'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 Monitor Audio Silver C250 7G has external dimensions of 205.0 x 482.0 x 274.0mm ( 8-1/16 x 18-15/16 x 10-3/4inch) .
Emotiva Airmotiv C3+ is clearly the larger of the two speakers. Its body is 909mm wider, 15mm taller and 38mm deeper than Monitor Audio Silver C250 7G.

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 Monitor Audio Silver C250 7G is approximately 1320.7cm2 / 204.7inch2. The Airmotiv C3+ requires 229% more surface area than the Silver C250 7G which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Emotiva Airmotiv C3+ weighs 26.80kg / 59lbs and the Monitor Audio Silver C250 7G weighs 10.63kg / 23.4lbs. This makes the Airmotiv C3+ 152% heavier than the Silver C250 7G.
Here is a comparison of how Airmotiv C3+ and Silver C250 7G's weights compare with the average, max and min weights in Passive Center Channel class.
