What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Dynaudio Confidence 3


As great truths are wont to do, the Confidence 3 is discrete about its qualities. We all know of much, much bigger loudspeakers 49.5 x 22.5 x 33.5 cm won't even impress a dwarf in very flat shoes - one of the reasons why the Confidence 3 has its personal dedicated stand). Or speakers with even more wallop (die-hard heavy metal fans will probably put on an aloof smile - at least until you turn the volume knob a little clockwise).But if true musical worth is what you're after, the Confidence 3 is in a class of its own. The tweeter is a special version of our justly famous Esotar T-330 D, which combines absolute brilliance with ultimate musicality - without the least bit of hardness. (You probably knew how it looks without realising it: the most reputed speakers in the world tend to be designed around this tweeter, a laudable step in the right direction.) With its ferrofluid-damped resonance and an aluminium voice coil which is lighter than a feather, it is not only at the outer frontier of the technologically feasible. It also puts an end to all diffuseness and tonal colouration.

Not in the least because the backwards-radiated energy of the Esotar (a democratic 50%), thanks to damping measures calculated by our famously reliable Danish engineers on high speed computers, is almost completely absorbed.

Which makes the Confidence 3 one of the few speakers that do not distract you with their own echo.
