Bang & Olufsen Beolab 8000 MK 2

Bang & Olufsen Beolab 8000 MK 2 was available with updated speaker units that provided more bass at low volumes starting in January 2003. The bass drivers of the more recent BeoLab 8000 MK 2 are noticeably better than those of their predecessors, even though they do not produce as much as a Beolab 2 (dedicated sub-woofer).

An enhanced ABL system and new frequency equalization were part of the improvement.

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.
