Reports[edit]
- HiFi Vision issue February/March 1989
- Sound: very good
- Workmanship: very good
- "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."
