I ask because, although they have not arrived yet, I am beginning to mull over the work needed on some wrecked, but only £1.23 worth, Goodmans Magisters. What surprises me is that Goodmans and other manufacturers of the time managed to use the same tweeter and midrange design in very different speakers, from small bookshelf types to the fifteen inch bass types of the Magister. I appreciate that work may ( or may not!) have been done to the crossovers, but given some peoples insistence of the critical nature of driver choice, how did they do it? P.S. Whilst googling for information, I came upon a tweet from late last year by Whispering Bob Harris thanking his Magisters for 40 odd years service, as he was finally retiring them off.
