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.

Sonus Faber Guarneri Memento

When, in 1994, Sonus Faber introduced the limited-edition Guarneri Homage loudspeaker to celebrate the 250th anniversary of the death of master violin maker Giuseppe Guarneri, the company embraced the musical-instrument analogy in the process of designing the speaker. Even the design of the enclosure relied more on techniques used to build musical instruments in the 18th century than on science-based, 21st-century loudspeaker technology.

The Guarneri's cabinet consists of 21 staves of thick, solid, hand-selected maple, separated by thin wooden strips, dyed aniline black, that are aged for two years before being kiln-dried. The wood is then shaped, assembled by hand, and glued, using heat and pressure techniques similar to those used for centuries in the making of violins. The cabinet's inner walls are lined as needed with copper sheeting (lead used to be in there as well, but use of the toxic heavy metal is no longer permitted), to distribute and damp resonances and produce cabinet-to-cabinet uniformity.

The cabinet's nonparallel walls are said to inhibit the generation of unwanted standing waves, and to help "guide" the backwave to the port. More important, the original Guarneri Homage, fitted with a custom-designed 6" Scan-Speak woofer and custom Dynaudio Esotar tweeter, received rave reviews across the board for both its measured and its musical performance.
