Akustik-regulering
Dæmpning af uønsket, reflekteret lyd fra gulv, loft og vægge




Lyd flaps som forhindrer lyden i at ramme gulv eller loft, 
og derfra ankomme til lyttepositionen med forsinkelse i forhold til den direkte lyd fra højttalerne.
Diffuserne på sidevæggene (se stort billed) har samme funktion.
Systemet sikrer, at højttalerne spreder lyden i et fladt bånd, som en akustisk linse, så man kun hører den direkte lyd.


Sund flaps - preventing early reflections from the floor and ceeling. Makes the speakers
speak for themselves almost without reflections. The Diffusers on the side walls will dampen side reflections.
The system makes the speakers behave as an acoustic lens, and so you will only hear the direct sound from the speakers

"ALT"
Acoustic Lens Technology from B&O




    

Mid tone and treble speakers are placed vertically under the lens-shaped discs to make the sound
spread in a narrow 30 degree horizontal plane - just like the light from a ship's lantern.
The discs prevents sound to bounce from the floor and the ceiling. Introduced in 2003




The new, inventive "BeoLab 5" speakers

Acoustic Lens Technology (ALT) 
Invented by Manny LaCarrubba of Sausalito Audio Works LLC  
The ATL technology
is a new and effective means to redistribute the acoustic power of a conventional dome radiator.
The resultant dispersion pattern has a very uniform frequency response over an extremely wide horizontal coverage angle
