Drivers
One of the fundamental differences between these two speakers is that Confidence 50 is a 3-way design whereas the Confidence 20 is a 2-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 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. On the other hand, the Confidence 20 features a 1.1" Esotar 3 Soft-Dome Tweeter and 1 x 7" MSP Woofer with a Crossover frequency at 2325 Hz.
Frequency Response
Confidence 50 has a frequency range of 35-22k Hz whereas Confidence 20 has a frequency range of 42-22k 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 Floor-standing class in our database.
Low Frequency
Floor-standing 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 50 is a 4 ohms speaker compared to the Confidence 20 which has a nominal impedance of 6 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.

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 50's and Dynaudio Confidence 20's external dimensions. 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) whereas 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).
Dynaudio Confidence 50 is 15mm narrower and 15mm less deeper than Dynaudio Confidence 20 but it is also 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 50 is approximately 869.8cm2 / 134.8inch2 and base area of the Dynaudio Confidence 20 is approximately 964.6cm2 / 149.5inch2. The Confidence 50 requires 10% less surface area than the Confidence 20 which gives it a small advantage on placement in tight spaces.
