History
What size room are the Dynaudio Contour 25Ci 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:

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Contour 25Ci and Contour 30i are 3-way speakers.

Contour 25Ci features a 1.1" Esotar 2i Soft-Dome Tweeter and 2 x 7" MSP Woofer with a Crossover frequency at (300)/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 25Ci has a frequency range of 35-23k Hz whereas Contour 30i has a frequency range of 32-23k Hz. With a minimum frequency of 32Hz, the Contour 30i can go slightly deeper then the Contour 25Ci's min frequency of 35Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Contour 25Ci and Contour 30i have the same Impedance of 4 ohms and their sensitivity is also same at 87 dB.
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 25Ci and the Contour 25Ci can provide this impedance level.
Sensitivity
Center Channel Speakers
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Contour 25Ci 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 25Ci 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
The size of a speaker can sometimes be 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 25Ci's and Dynaudio Contour 30i's external dimensions. Dynaudio Contour 25Ci has external dimensions of 215.0 x 750.0 x 396.0mm (8-7/16 x 29-1/2 x 15-9/16inch) 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).
Dynaudio Contour 30i is 535mm narrower and 36mm less deeper than Dynaudio Contour 25Ci but it is also 925mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Dynaudio Contour 25Ci needs about 284% more floor or shelf area. Dynaudio Contour 25Ci is 36mm deeper, so it stands that much further out from the wall. Dynaudio Contour 30i is 925mm 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 Dynaudio Contour 25Ci is approximately 2970.0cm2 / 460.4inch2 and base area of the Dynaudio Contour 30i is approximately 774.0cm2 / 120.0inch2. The Contour 25Ci requires 284% more surface area than the Contour 30i which gives it a small disadvantage on placement in tight spaces.
