What size room are the Revel Performa3 C205 and KEF R2c 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 Revel Performa3 C205 and KEF R2c 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 Revel Performa3 C205 is a 2-way design whereas the R2c 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.

Revel Performa3 C205 features a 1" aluminum dome with proprietary acoustic lens and waveguide Tweeter and 2 x 5.25" aluminum cone with cast frames Woofer . On the other hand, the R2c features a 1" aluminum Dome Tweeter , a 5" Midrange and 2 x 5.25" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
Revel Performa3 C205 has a frequency range of 80Hz- 20kHz whereas R2c has a frequency range of 74-28k Hz. With a minimum frequency of 74Hz, the R2c can go significantly deeper on the low side and provide stronger bass compared to the Revel Performa3 C205's min frequency of 80Hz.
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
Revel Performa3 C205 and R2c have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Revel Performa3 C205 sensitivity is rated at 89 dB and the R2c's is at 87 dB. This 2 dB difference makes the Revel Performa3 C205 a more sensitive speaker compared to KEF R2c, 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.
Revel Performa3 C205 can handle a max power of 200 watts RMS from the amp the whereas Revel Performa3 C205 has a max power handling value of 120 watts RMS , 80 watts less than the R2c.
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
R2c features Binding post posts which make bi-amping or bi-wiring possible. Revel Performa3 C205 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 Revel Performa3 C205's and KEF R2c's external dimensions. Revel Performa3 C205 has external dimensions of 207.0 x 535.0 x 294.0mm ( 8-1/8 x 21-1/16 x 11-9/16inch) whereas KEF R2c has external dimensions of 177.0 x 551.0 x 316.0mm ( 6-15/16 x 21-11/16 x 12-7/16inch) .
Revel Performa3 C205 is 16mm narrower and 22mm less deeper than KEF R2c but it is also 30mm taller.
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 Revel Performa3 C205 is approximately 1572.9cm2 / 243.8inch2 and base area of the KEF R2c is approximately 1741.2cm2 / 269.9inch2. The Revel Performa3 C205 requires 10% less surface area than the R2c which gives it a small advantage 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 Revel Performa3 C205 weighs 11.86kg / 26.1lbs and the KEF R2c weighs 16.90kg / 37.2lbs. This makes the R2c 42% heavier than the Revel Performa3 C205.
Here is a comparison of how Revel Performa3 C205 and R2c's weights compare with the average, max and min weights in Passive Center Channel class.
