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.

Arcam Three plus

Arcam Three - Ultra compact audio monitor loudspeakers

The Arcam series of loudspeakers from A&R Cambridge are well engineered moving coil loudspeakers which provide excellent sound quality at affordable prices. They qre the result of several years of intensive research by A&R's designers into ways of achieving outstanding musical fidelity from compact sensibly priced speaker system

All three loudspeakers are classic UK two way designs, using selected tweeters and A&R designed plastic coned bass drivers. These are otimally matched to rear ported (reflex) loaded cabinets, solidly constructed from high density 18 mm board with ultra rigid 19 mm "Medite" front baffles. The larger cabinets are heavily cross braced and damped,, to minimise cabinet resonances.
The Arcam Three+ is offered with a well finished walnut or black ash type vinyl wrap. All models have attractive removable black reticulated foam grilles of high acoustic transparency.
