History
What size room are the Dynaudio Contour 20i and Dynaudio Contour 30i 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:

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 Dynaudio Contour 20i and Dynaudio Contour 30i 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 Contour 20i is a 2-way design whereas the Contour 30i 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.

Contour 20i features a 1.1" Esotar 2i Soft-Dome Tweeter and 1 x 7" MSP Woofer with a Crossover frequency at 2200 Hz. On the other hand, the Contour 30i features a 1.1" Esotar 2i Soft-Dome Tweeter and 2 x 7" MSP Woofer with a Crossover frequency at (300)/2200 Hz.
Frequency Response
Contour 20i has a frequency range of 39-23k Hz whereas Contour 30i has a frequency range of 32-23k Hz. With a minimum frequency of 32Hz, the Contour 30i can go significantly deeper on the low side and provide stronger bass compared to the Contour 20i's min frequency of 39Hz.
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.

Bookshelf Speakers
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
Contour 20i and Contour 30i have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Contour 20i sensitivity is rated at 86 dB and the Contour 30i's is at 87 dB. This 1 dB difference makes the Dynaudio Contour 30i a more sensitive speaker compared to Dynaudio Contour 20i, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Contour 20i and the Contour 20i can provide this impedance level.

Input Type and Bi-Amping / Bi-Wiring
Contour 20i features Binding post type posts and Contour 30i has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Contour 20i and Contour 30i 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 Contour 20i's and Dynaudio Contour 30i's external dimensions. Dynaudio Contour 20i has external dimensions of 440.0 x 215.0 x 360.0mm ( 17-5/16 x 8-7/16 x 14-3/16inch) whereas Dynaudio Contour 30i has external dimensions of 1140.0 x 215.0 x 360.0mm ( 44-7/8 x 8-7/16 x 14-3/16inch) .
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 Contour 20i is approximately 774.0cm2 / 120.0inch2 and base area of the Dynaudio Contour 30i is approximately 774.0cm2 / 120.0inch2.
