The Dynaudio Confidence 20 is a bookshelf speaker from the Confidence range, the top tier of the Danish manufacturer's current catalogue. It is a large design intended for use on stands.
Key specs that matter
Dynaudio quotes a frequency range of 42 Hz to 22 000 Hz. Sensitivity is 87 dB and nominal impedance is 6 ohms, with amplification recommended up to 250 W. The cabinet measures 23.3 x 52.0 x 41.4 cm and weighs 27 kg, making it larger and heavier than most speakers of its type.
Pairing
That sensitivity and power recommendation mean the Confidence 20 needs a strong amplifier that can deliver plenty of current.
Alternatives
Dynaudio's Emit 20 from the more accessible Emit range is a bookshelf speaker at a considerably lower price and is easier on the amplifier.
