Just a comment on Horning speakers. They really do need to be carefully matched to the room. Most are mismatched; usually the room is too small for the speaker and they need rear wall reinforcement below 200hz because of the isobarik configuration of the 8 drivers. Jeff Catalino does a pretty good job of getting the best out of them in the USA. They do not appear to be a 'popular' speaker, more a sleeper like the De Vore's and Zu's
