History
What size room are the Dynaudio Confidence 20 and Dynaudio Confidence 50 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
One of the fundamental differences between these two speakers is that Confidence 20 is a 2-way design whereas the Confidence 50 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.

Confidence 20 features a 1.1" Esotar 3 Soft-Dome Tweeter and 1 x 7" MSP Woofer with a Crossover frequency at 2325 Hz. On the other hand, the Confidence 50 features a 1.1" Esotar 3 Soft-Dome Tweeter, a 6" Midrange and 2 x 7" MSP Woofer with a Crossover frequency at 200/2860 Hz.
Frequency Response
Confidence 20 has a frequency range of 42-22k Hz whereas Confidence 50 has a frequency range of 35-22k Hz. With a minimum frequency of 35Hz, the Confidence 50 can go significantly deeper on the low side and provide stronger bass compared to the Confidence 20's min frequency of 42Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
Confidence 20 is a 6 ohms speaker compared to the Confidence 50 which has a nominal impedance of 4 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 Confidence 50 can provide this impedance level.
On the other hand, they have the same sensitivity of 87 dBdB.

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
Confidence 20 features Binding post type posts and Confidence 50 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both Confidence 20 and Confidence 50 have down firing ports.
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 Confidence 20's and Dynaudio Confidence 50's external dimensions. Dynaudio Confidence 20 has external dimensions of 520.0 x 233.0 x 414.0mm (20-1/2 x 9-3/16 x 16-5/16inch) whereas Dynaudio Confidence 50 has external dimensions of 1512.0 x 218.0 x 399.0mm (59-1/2 x 8-9/16 x 15-11/16inch).
Dynaudio Confidence 50 is 15mm narrower and 15mm less deeper than Dynaudio Confidence 20 but it is also 992mm 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 Confidence 20 needs about 11% more floor or shelf area. Dynaudio Confidence 20 is 15mm deeper, so it stands that much further out from the wall. Dynaudio Confidence 50 is 992mm 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 Confidence 20 is approximately 964.6cm2 / 149.5inch2 and base area of the Dynaudio Confidence 50 is approximately 869.8cm2 / 134.8inch2. The Confidence 20 requires 11% more surface area than the Confidence 50 which gives it a small disadvantage on placement in tight spaces.
