What size room are the Dynaudio Evoke 20 and KEF R3 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 Dynaudio Evoke 20 and KEF R3 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 Evoke 30 is a 2-way design whereas the R3 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.

Evoke 30 features a 1.1" Cerotar with Hexis Tweeter and 1 x 7" Magnesium Silicate Polymer Woofer with a Crossover frequency at 3200Hz. On the other hand, the R3 features a 1" aluminum Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz.
Frequency Response
Evoke 30 has a frequency range of 40-23k Hz whereas R3 has a frequency range of 52-28k Hz. With a minimum frequency of 40Hz, the Evoke 30 can go significantly deeper on the low side and provide stronger bass compared to the R3's min frequency of 52Hz.
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 Bookshelf class in our database.

High Frequency
Bookshelf 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
Evoke 30 is a 6 ohms speaker compared to the R3 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Evoke 30 sensitivity is rated at 86 dB and the R3's is rated at 87 dB. This 1 dB difference makes the KEF R3 a more sensitive speaker compared to Dynaudio Evoke 20, 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
R3 features Binding post posts which make bi-amping or bi-wiring possible. Evoke 30 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Evoke 30 and R3 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 Dynaudio Evoke 20's and KEF R3's external dimensions. Dynaudio Evoke 20 has external dimensions of 380.0 x 215.0 x 343.0mm ( 15 x 8.5 x 12.1inch) whereas KEF R3 has external dimensions of 423.0 x 199.0 x 337.0mm ( 16-5/8 x 7-13/16 x 13-1/4inch) .
KEF R3 is 16mm narrower and 6mm less deeper than Dynaudio Evoke 20 but it is also 43mm taller.
Below you can see the front view size comparison of Dynaudio Evoke 20 and KEF R3 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 Dynaudio Evoke 20 is approximately 737.5cm2 / 114.3inch2 and base area of the KEF R3 is approximately 670.6cm2 / 103.9inch2. The Evoke 30 requires 10% more surface area than the R3 which gives it a small disadvantage on placement in tight spaces.
