Like the Evidences, the C4 is a tall, narrow floorstander with twin tweeters flanked first by twin midrange units, then by twin woofers. In combination with the first-order crossover slopes, this vertically symmetrical array of drive-units narrows the vertical radiation pattern, resulting in a claimed 75% reduction in the energy reflected from the ceiling and floor. Referred to by the manufacturer as Dynaudio Directivity Control (DDC) and reminiscent of the similar arrays used by John Dunlavy in his designs for Duntech and DAL, this will make the speaker’s sound less dependent than usual on individual room acoustics.

Usually, having spaced tweeters covering identical frequency ranges will result in some top-octave vertical lobing as the drivers’ outputs interfere away from the central axis. However, in the DDC array, the upper tweeter is used only between 3kHz and 8kHz, to narrow the vertical dispersion in the region where the radiating diameter would otherwise be smaller than the wavelengths of sound being emitted, reducing the presence-region “flare” in the speaker’s reverberant soundfield.

The Confidence C4′s tweeter is the new Esotar2 unit, which is also used in the Danish company’s 25th-anniversary Special 25 loudspeaker.A ferrofluid-cooled, 28mm, fabric-dome type, the Esotar2 uses a powerful neodymium magnet and aluminum voice-coil wire. Both the 6″ midrange drivers and the 8″ woofers feature molded plastic cones loaded with mineral powder (magnesium silicate), and again use low-mass aluminum wiring. Each of the woofers is reflex-loaded with a 2.75″-diameter port with flared inner and outer openings on the rear of the enclosure.
