What size room are the Emotiva Airmotiv C2+ and Monitor Audio Radius 200 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 C2+ Monitor Audio Radius 200
Near-field Poor Poor
Small Room Average Average
Mid-size Room Good Good
Large Room Average Average
Very Large Room Poor 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 C2+ and Monitor Audio Radius 200 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 Radius 200 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.

Driver Emotiva Airmotiv C2+ Monitor Audio Radius 200
Driver Setup 3-way 2-way
Tweeter 25×32 mm-inch 1-inch
Midrange 2 x 3-inch -
Woofer 2 x 6.5-inch 2 x 4-inch

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 Radius 200 features a 1" gold dome C-CAM Tweeter and 2 x 4" C-CAM Woofer .

Frequency Response

Airmotiv C2+ has a frequency range of 45 Hz – 28 kHz whereas Radius 200 has a frequency range of 60-35k 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 Radius 200's min frequency of 60Hz.

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 Radius 200 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 Radius 200's is rated at 86 dB. This 6 dB difference makes the Emotiva Airmotiv C2+ a more sensitive speaker compared to Monitor Audio Radius 200, 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 C2+ features Binding post posts which make bi-amping or bi-wiring possible. Radius 200 has a 5-Way 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 C2+'s and Monitor Audio Radius 200'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 Monitor Audio Radius 200 has external dimensions of 126.0 x 331.0 x 162.0mm ( 4-15/16 x 13 x 6-3/8inch) .

Emotiva Airmotiv C2+ is clearly the larger of the two speakers. Its body is 481mm wider, 94mm taller and 105mm deeper than Monitor Audio Radius 200.

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 Monitor Audio Radius 200 is approximately 536.2cm2 / 83.1inch2. The Airmotiv C2+ requires 304% more surface area than the Radius 200 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 C2+ weighs 16.40kg / 36.1lbs and the Monitor Audio Radius 200 weighs 3.59kg / 7.9lbs. This makes the Airmotiv C2+ 357% heavier than the Radius 200.

Here is a comparison of how Airmotiv C2+ and Radius 200's weights compare with the average, max and min weights in Passive Center Channel class.
