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.

Braun L500A ADS loudspeakers

Braun - Invisibile Sound

Transparent has been the word used by experts to describe the best in clear, distortion free sound. But now there is something better 


 

Braun introduces a new dimension in sound. And a new word to describe it. The invisible sound of Braun loudspeakers is a giant step beyond transparency. Deep rich lows. Clean crisp highs. Powerful, perfectly natural sound - free of distortion and distraction. Recorded music now has an authentic presence you've never experienced before.

And it's no surprise. Braun loudspeakers are perhaps the most highly regarded speakers in Europe. There, they are the standard by which all others are judged. Now these incomparable performers are available in the United States, but not at "import" prices. Braun loudspeakers are currently being assembled in Cambridge Massachusetts from imported German driver components. This has dramatically cut cost, but not performance. With Braun you have superb German engineering plus the highest quality speaker cabinets made in the Unitee States with the same craftsmanship as those from the "old country".

If the quality of Braun's had to be traced to a single source it would have to be the European precision engineering applied to the evolved concept of the acoustic suspension speaker. Not many companies design and produce their own drivers and crossovers

 

The L-500A is two-way acoustic suspension speakers. Truly good tw-way systems are difficult to design since woofer and tweeter have to cover a rather wide range of frequencies.
