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.

EISA 2012-2013 KEF LS 50

 To casual viewers the LS50 will look like a minimalist, single-driver loudspeaker but in reality it’s more sophisticated. In fact, this single driver is one of KEF’s famous two-way Uni-Q units with its tweeter mounted at the acoustic centre of the mid/woofer. This latest iteration, coloured rose gold, features a cone formed of a special magnesium/aluminium alloy and benefits from a longer ‘throw’ to improve bass performance. The cabinet is not only beautifully finished but is sturdily constructed with constrained layer damping between its walls, internal cross-brace and front baffle. As promised, the LS50 delivers a remarkably big sound with vivid imaging and a tremendous bass weight that belies its compact dimensions. Shut your eyes and you’ll believe you are listening to a far bigger loudspeaker.
