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.

B&W DM-580


DM580
Floor-standing loudspeaker system

Product Summary
The DM580 is a prodigious floor-standing three-way system in the finest B&W tradition, covering the entire frequency range and offering critical enjoyment over the whole spectrum of musical experience.
The rear vented enclosure has been precisely tuned to intergrate with the drive units and simplified crossover. Matrix technology has influenced the critical bracing of the enclosure which is further strengthened by separate mounting the tweeter, bass/midrange and bass units.

Technical highlights
B&W's Tweeter technology ensures that the sound remains focused and time sensitive and that the stereo image is presented with unparalleled three dimensional accuracy.
The cabinets feature a specially designed high density front baffle which achieves almost Matrix-like stability in strengthening overall enclosure construction. The bevel edges of the front moulding reduce diffraction and improve dispersion. The crossover components use heavy gauge wire throughout and new drivers guarantee not only high reliability but ensure that top specifications are met.
