:: "The BM 20 mastered impulsive pop music with aplomb: once again, this speaker proved to be very dynamic, effortlessly putting away juicy impulse peaks. But once again the testers wished for a touch more fundamental warmth and a somewhat deeper room imaging."

:: "Impulsreiche Popmusik meisterte die BM 20 souverän: Wiederum erwies sie sich als sehr dynamische Box, die mühelos saftige Impulsspitzen wegsteckte. Aber auch diesmal wünschten sich die Tester wieder eine Spur mehr Grundtonwärme und eine etwas tieferreichende Raumabbildung."
