Bose never really took off as domestic speakers in the UK -- perhaps in part due to poor reviews and perhaps thanks to their poor reaction to criticism in the UK hifi press.
One early review described the 901s using rather colourful comparisons.
Where a British company probably would have tried to fix the problem with the speakers, Bose tried to fix the reviewer with a threat of legal action.
After that, other journalists may have simply avoided mentioning Bose products, denying them exposure in the UK.
