Very good looking and sounding compact stereo active speaker system. BeoLab 2500 are active speakers designed to match the BeoSound Ouverture and BeoSound 3000. With their built-in amplifiers, they sound like they are three times their size. Active speaker of 59 watts Woofer: 11 cm Tweeter: 2.5 cm 2 x PowerLink Item condition: Traces of use on the back Designer: David Lewis Carefully insured shipped Adaptive Bass Linearisation (ABL) is a process patented by B&O and is incorporated in BeoLab loudspeakers. The idea is to use the surplus capacity in amplifiers and driver units, arising by normal listening levels, for a bass extension – a sound reproduction with more bass, than the loudspeaker otherwise would be able to produce. The function is adaptive. This means that the loudspeaker adapts to the signal it receives. Loudspeaker drivers are therefore fully exploited, without suffering mechanical or electronic abuse, and the built in amplifiers are not subjected to signals would otherwise create an overload situation. ABL gives stunning bass reproduction considering the size of the loudspeaker in which it is incorporated, under normal listening levels.
