New Loudspeaker Eliminates Distortive Influence

fejrskov writes "The Danish audio/video company 'Bang & Olufsen' announced a new loudspeaker which promises to eliminate the bad influence from walls, floors and ceilings on the sound. This is achieved by using two technologies: ALT (Acoustic Lens Technology) uses sound dispersing lenses to make sound travel equally in all directions. ABC (Adaptive Bass Control) involves sliding a tiny microphone out at the base of the speaker, playing a series of test sounds, and adapting the bass according to the measured acoustic response. Each active loudspeaker contains amplifiers for a total of 2500W (!) output using B&O's patented ICEPower concept. The price? Approximately 55.000 Danish kroner (8.000 Euro) each."
